Span Gain is related to A/D integration time. The larger the span gain, the higher the internal resolution, but the slower the update speed.

Selects the range within which the Force Meter will automatically zero. Note that the Force Meter must be in standstill to automatically zero. Selections are in Display Divisions. “d” = graduation

Selects the range within which the Force Meter may be zeroed. Note that the indicator must be in standstill to zero the Force Meter.

Sets the level at which motion is detected by comparing the present display update with the previous one. If motion is not detected for two seconds or more, Force Meter is in standstill and can process a Print or Zero command. Maximum value varies depending on local regulations.

Averages weight readings to produce higher accuracy. The higher the filter number, the greater the accuracy but the slower the response time. Choose 4 or 8 unless a very fast response is needed.

Selects the desired formula which determines the point at which the indicator shows overload (""). All selections are based on the primary unit selected in F8.

"FS" = Full Force Meter in primary units.

Selects the primary base unit to be used in the calibration process. Also the default unit for normal operation. "1" = primary unit is lb. "2" = primary unit is in kg.

Determines the desired weight increments. Value should be consistent with legal requirements.

Determines location of the decimal point.

We recommend the Force Meter to be calibrated at yearly intervals. The minimum test force that can be used is 70% of full-Force Meter capacity.

To calibrate the zero point using the F16 zero calibration procedure:

1. Turn the power OFF

2. Press the Calibration Switch once.

3. Turn the power ON and the display will show F1, if not go back to point 1.

4. Scroll to "F 16". Use the TARE or PRINT key to move up or down. (If necessary press O to go back to parameter number.)

5. Press ZERO. The display will momentarily show "C 0" followed by a value. (If necessary press O to go back to parameter number.)

6. After making sure that there are no weights on the platform, press ZERO to zero out the displayed

TARE

To calibrate the max point using the F17 span calibration procedure:

1. Scroll to "F 17", then press ZERO to enter span calibration menu.

2. The display will momentarily show "C 1" for the span calibration, followed by a value with one flashing digit. This

value will be zero. Place the test force on the Force Meter.

3. Pressing TARE or ON will change the position of the flashing digit.

4. Increase the flashing digit by pressing O. Decrease the flashing digit by pressing ZERO.

5. After setting the exact value, press NET to save the value.

6. If the calibration was successful, the display will show "EndC1" momentarily, and then revert back up to F17.

"Err0" – The calibration test force or the adjusted keyed-in weight is larger than the full capacity of

the Force Meter. Change the calibration test force or check the input data.

"Err1" – Change the calibration test force or check the input data. "Err2" – The internal resolution of the Force Meter is not high enough to accept the calibration value.

Select a larger parameter for the Span Gain (F2).

7. Press Calibration Switch one time for normal mode.

Fault localization

If the Weighingblock is “dead”.

1. Check the battery. Use only a 9 V alkaline battery.

If the Force Meter starts but the display shows wrong.

1. Calibrate the Force Meter.

2. If it not works.

3. The Force Meter must be demounted.

Demounting.

1. Demount the Weighingblock carefully.

2. Check the inside visually. Look for bad cables and connections.

3. If needed, clean the PC-board.

If the Force Meter shows F1

1. Probably has the Calibration Switch been changed to calibration mode?

2. Reset to normal mode.

3. Press OFF and ON.

Check the Loadcell

1. Check the Loadcell with a universal volt instrument, see encl table. The pin close to the corner is number 1.

Pin Description

1 Out +5VDC 2 In + 3 Out 0 VDC

Check the excitation voltage, it should be aprox 5 VDC. The

output from the Loadcell (pin 2 and 4) will increase from

aprox. 0 to 10 mV for the capacity range.

4 In -

If some parameters by mistake has been changed.

1. If only the first,F1, has been changed. Set back to right value in accordance to the table.

2. If many parameters has been changed. Check all parameter values. Probably it is necessary to calibrate the Weighingblock.
