A. GENERAL INFORMATION

    A.1 Operation Features

    ? Internal digital sampling rate of 16,000 samples per second.

    ? Easy operation with a four-key rubber keypad.

    ? Easy two point calibration and calibration by sensitivity setting of both interchangeable integral and

    remote load cells.

    ? Easy installation of interchangeable integral (FDXE) and remote (FDXE-R) load cells.

    ? Easy calibration adjustment to fine tune calibration or for accuracy checking.

    ? In AVERAGE mode, the gage automatically averages 2,000 real-time samples and captures both

    tension and compression peak forces at 16,000 samples per second. The gage automatically

    displays the average force 8 times per second. The display indicates “T” for tension or “C” for

    compression corresponding to the direction of the applied load.

    ? In PEAK mode, the gage automatically captures both tension and compression peak forces at

    16,000 samples per second and displays peak force.

    ? PEAK mode may be engaged prior to testing to capture and display the real-time tension or

    compression peak forces at 16,000 samples per second. It may also be engaged after a test to

    display the tension or compression peak force.

    ? Selectable units are lbf (ozf), kgf (gf) or N. The 250 gf gage has selectable units of ozf, gf or N. ? A battery pack of five rechargeable NiCad batteries allows 8 hour of continuous battery operation with

    8-10 hours charge or continuous AC operation via the accompanying charger. ? Low battery indicator when first displayed for fully charged batteries indicates there is approximately

    20 minutes before the batteries require recharging.

    ? Two battery chargers for 115 Vac and 220 Vac are available. To charge the batteries, plug the

    accompanying charger into the proper AC main and insert the charger plug into the jack on one end

    of the gage. Charging the batteries for 8-10 hours yields approximately 8 hours of continuous

    operation. The batteries can be recharged more than 600 times.

    ? To increase battery life, after the batteries have been charged for 8-10 hours, the charger plug

    should be removed from the gage or if the charger is always connected to the gage, the gage should

    not be powered off.

    ? Automatic power off feature preserves battery life. The gage powers off if it idles for 20 minutes.

    Operator may deactivate this feature if desired.

    A.2 Physical Design Features

    ? A four-key rubber keypad.

    ? Die-cast aluminum reversible housing. Split housing design permits upright display whether gage is

    hand held or test stand mounted.

    UNITS Selects and saves unit in memory and updates the displayed value in the selected unit. PEAK Returns to AVERAGE mode.

D. INTERCHANGING FORCE CELL MODULES

    D.1 Connecting a new Integral Force Cell Module (FCMX)

    To install an interchangeable integral Force Cell Module, the capacity and sensitivity value of the new Module’s load cell need to be entered into the display module.

    6 of 12

The sensitivity value used for gage calibration and set-up is the actual full scale mV/V signal output of the

    gage load cell. Each load cell has it’s own “signature” sensitivity value, which is marked directly and

    clearly on the load cell. The sensitivity value should be nominally close to 2.0000, the specified full scale

    signal output of the FDXE load cell.

    Sensitivity calibration should be used to install a new load cell with measured sensitivity into the gage.

    Use the procedures and examples below to calibrate the gage with a 50 lb load cell with sensitivity of

    1.9873 mv/v. The gage was previously calibrated with a 5 kg load cell with sensitivity of 2.0123 mv/v.

    1. Power off the gage. Detach the back half of the gage, the Force Cell Module (FCMX 10), from the

    front half of the gage, the Force Display Module. Note the sensitivity value of the new FCMX 50

    Force Cell Module (1.9873), written clearly on the unit, as it will be required for resetting the gage

    after the gage has been resealed. Carefully attach the FCMX 50 Module to the front half of the gage,

    the Force Display Module using two socket screws located on the gage back. Power on the gage to

    check the full connection of the FCMX 50.

    2. Power off the gage. While holding down ON/OFF, press PEAK followed by ZERO, then release

    ON/OFF to access the calibration menu. The current programmed unit and capacity “5.000 kgf” is

    displayed and blinking. The blinking display indicates that the displayed value is the current

    programmed unit and capacity.

    Use the steps below to select the new capacity.

    3. IMPORTANT: UNITS MUST BE SET ON “kgf” MODE WHILE ENTERING NEW LOAD CELL

    SENSITIVITY VALUE. If testing requires the “lbf” or “N” mode, reset UNITS only after exiting the set-

    up mode to avoid corrupting gage calibration.

    4. Press PEAK to step through the available capacities until “25.00” (25.00 kgf corresponds to the

    50.00 lbf UNIT setting) is displayed. Press ZERO to enter a newly selected capacity or to continue to

    the next parameter if no changes are made.

     Use the steps below to enter the sensitivity of 1.9873 mv/v of the new load cell.

     Key functions for sensitivity calibration are as follows:

     UNITS Changes value of individual digit.

     PEAK Selects which digit to change.

     ZERO Enters/Saves new selection.

    5. Once the capacity setting is made, the display blinks and displays the digit “2” (value before the

    decimal point) of the sensitivity of 2.0123 mv/v of the previous load cell. The digit “2” is blinking to

    indicate that this digit is being set.

    6. Press UNITS to step through the available values until “1” is displayed.

    7. Press ZERO to select the “1”, and then “.0123” (value after the decimal point) of the sensitivity of

    2.0123 mv/v of the previous load cell is displayed. The most right digit “3” is blinking to indicate that

    this digit is being set.

    8. Note that the most right digit “3” need not be changed. Proceed to step 9.

    9. Press PEAK to move the cursor to the next digit “2” on the left. The digit “2” is blinking to indicate that

    this digit is being set.

    10. Press UNITS to step through the available values until “.0173” is displayed.

    7 of 12

11. Repeat steps 8 and 9 until “.9873” is displayed.

    12. Press ZERO to enter the sensitivity of 1.9873 mv/v of the new load cell into memory. The display

    blinks and calibration is complete.

    D.2 Connecting a new Remote Force Cell Module (FCX)

    To install an interchangeable remote load cell, only the capacity of the gage needs to be changed. Use

    the procedures and examples below to install an interchangeable remote 50 lb load cell. The gage was

    previously calibrated with a 5 kg interchangeable remote load cell.

    1. Power off the gage. While holding down ON/OFF, press PEAK and follow by ZERO, then release

    ON/OFF to access the installation menu. The current programmed unit and capacity “5.000 kgf” is

    displayed and blinking. The blinking display indicates that the displayed value is the current

    programmed unit and capacity.

    Use the steps below to select the new capacity.

    2. IMPORTANT: UNITS MUST BE SET ON “kgf” MODE WHILE ENTERING NEW LOAD CELL

    SENSITIVITY VALUE. If testing requires the “lbf” or “N” mode, reset UNITS only after exiting set-up

    mode to avoid corrupting gage calibration.

    3. Press PEAK to step through the available capacities until “25.00” (25.00 kgf corresponds to the

    50.00 lbf UNIT setting) is displayed. Note that if capacity need not be changed, skip this step. 4. Press ZERO to enter the selected capacity into memory. The display blinks and installation is

    complete.

    E. CALIBRATION

    E.1 Complete Calibration

    Complete calibration should only be used to calibrate a gage for the very first time during manufacture.

    Use the procedures and examples below to calibrate a gage with a 50 lb load cell with sensitivity of

    2.0100 mv/v. The gage was previously calibrated with a 5 kg load cell with sensitivity of 1.9880 mv/v.

    Although calibration may be performed using certified lbf, kgf, or N weights, THE SENSITIVITY VALUE

    SHOWN ON EACH FORCE CELL MODULE CORRESPONDS TO CALIBRATION IN “kgf”. If calibration

    is performed in the “lbf” or “N” mode, the sensitivity value registered may differ from the value marked on

    the unit. Calibration in “lbf” or “N” is valid, but if the gage is rematched with another Force Cell Module,

    the sensitivity value must be entered while the gage set-up is in “kgf” mode.

    1. Power off the gage. Setup the gage for tension or compression load, including weight hangers, hooks

    or fixtures needed to load the full gage capacity. While holding down ON/OFF, press UNITS, followed

    by ZERO and then release ON/OFF to access the calibration menu. The current programmed unit

    and capacity “5.000 kgf” is displayed and blinking. The blinking display indicates that the displayed

    value is the current programmed unit and capacity. Allow 5 minutes for stabilization prior to

    calibration.

    Use the steps below to select the new unit and capacity.

    2. Press UNITS to step through the available units until “lbf” is displayed. Press ZERO to enter a newly

    selected unit or to continue to the next parameter if no changes are made.

    8 of 12

    3. Press PEAK to step through the available capacities until “50.00” is displayed. Press ZERO to enter

    a newly selected capacity or to continue to the next parameter if no changes are made.

    4. The display blinks and displays “CAL” and the selected capacity of the new load cell “50.00”.

    Use the steps below to read the calibration data for simulated 50 lb and 0 lb load.

    5. Load 50 lb of dead weight on the gage and allow the dead weight to stabilize. Press ZERO to read

    the calibration data for 50 lb. The gage then displays “0.00”. 6. Remove the 50 lb dead weight. Allow to stabilize and press ZERO to read the calibration data for 0

    lb. The gage has now captured the calibration values for 0 lb and 50 lb.

    Use the steps below to enter the sensitivity of 2.0100 mv/v of the new load cell.

    7. The display blinks and displays the digit “1” (value before the decimal point) of the sensitivity of

    1.9880 mv/v of the previous load cell. The digit “1” is blinking to indicate that this digit is being set.

    8. Press UNITS to step through the available values until “2” is displayed. 9. Press ZERO and then “.9880” (value after the decimal point) of the sensitivity of 1.9880 mv/v of the

    previous load cell is displayed. The most right digit “0” is blinking to indicate that this digit is being set.

    10. Note that the most right digit “0” need not be changed. Proceed to step 11.

    11. Press PEAK to move the cursor to the next digit “8” on the left. The digit “8” is blinking to indicate that

    this digit is being set.

    12. Press UNITS to step through the available values until “.9800” is displayed.

    13. Repeat steps 11 and 12 until “.0100” is displayed. 14. Press ZERO to enter the sensitivity of 2.0100 mv/v of the new load cell into memory. The display

    blinks and calibration is complete.

    E.2 Calibration Adjustment

    Calibration adjustment may be used to fine tune calibration or for accuracy checking. Use the procedures

    and examples below to adjust calibration using calibrated dead weight.

    1. Setup the gage for tension or compression load. Power on the gage. Allow 5 minutes for stabilization

    prior to calibration adjustment. While holding down ZERO, press UNITS and then release ZERO to

    access the calibration adjustment menu. The gage displays “SET” to indicate that it is in calibration

    adjustment menu.

    2. Load the calibrated dead weight on the gage.

    3. If the displayed value is less than the calibrated dead weight, press UNITS to increase the displayed

    value until it matches the calibrated dead weight.

    4. If the displayed value is greater than the calibrated dead weight, press PEAK to decrease the

    displayed value until it matches the calibrated dead weight.

    5. Once the displayed value matches the calibrated dead weight, other calibrated dead weight may be

    used to check the calibration.

    6. Note that the calibration adjustment can be discarded by pressing ON/OFF to power off the gage.
