POWER SUPPLY AC Adapter If the indicator is powered by an adapter, plug the adapter directly into the “DC” pin located at the bottom of the indicator. We recommend to plug into a wall outlet to avoid interference with other wirings. Battery (Optional) If you have an indicator with the rechargeable battery option, please charge the internal battery fully before first time use. A 110 to 220V AC adapter should be provided with your indicator.

DISPLAY AND KEY DESCRIPTION ON/OFF Powers the Indicator On or Off if held for 2 seconds Hold 1. Peak hold - Grabs the highest weight (for tension and pulling force) 2. Data hold - Holds the current weight value (ex. for use with weighing moving animals) TOTAL 1. Accumulates weights 2. Works with “Print” to perform the accumulation function and check the accumulation result UNITS Shifts between weighing units (kg/lb) COUNT Use the scale to count product based on a sample weight TARE 1. Zero’s the scale.
OPERATING INSTRUCTIONS Power On ●● Turn on the power by pressing the power button for 2 seconds. Once on, the scale will flash the voltage and then begin to auto-check and count down from 0-9 sequentially before entering the weighing mode Note: Anything on the scale before powering on will automatically be tared out.
Accumulation ●● In weighing mode load the first weight, once stable press the ACCUM key to enter the accumulation mode. The “total” light will display.
CALIBRATION PROCEDURE 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 21. 22. 23. 24. 25. Turn on the scale by holding the ON/OFF key. (If the scale does not turn on, plug in the ac adapter because the battery is low.) Press the HOLD key and the PRINT key simultaneously to access the setup menu. If done correctly, the display should now show C01. Press the PRINT key to access the C1 channel. The display should show [C1 X]. Press the ZERO key to change the value of C1 to 2.
26. The scale will count down from 10 to 0. Once 0 has been reached, the display will show CALEnd. 27. Press the PRINT key to continue. The display will now show C07. 28. Press the ACCUM/TOTAL key to save and exit the setup menu. 29. The scale has now been calibrated. The display will show the value of the calibration weight on the scale. 30.
INDICATOR PARAMETER SETTINGS The parameter settings menu has a calibration section (C01 to C07 explained above) and a parameter settings section (C08 and up). To access the calibration section the seal switch (located at one corner of the PCB) must be OFF. This will allow access to all C01 and up settings. If the seal switch is ON, then only C08 and up can be accessed by the user.

4-20 mA ANALOG OUTPUT (OPTIONAL) FIGURE 6. CONNECTION DIAGRAM The 4-20 mA analog output of the OP-900 scale is a voltage sourcing sensor that will output current which is proportional to the calibrated scale’s weight range (i.e. 4 mA = 0 LBS and 20 mA = 10,000 LBS). It is important to note, that this is a sourcing output sensor (i.e. the sensor will source 9VDC with an output current range of 4-20 mA).
RELAY OUTPUT (OPTIONAL) ●● The indicator can output 4 signals, which when connected to outside equipment, can perform an automatic control function and an upper/lower limit alarm function.
TROUBLESHOOTING Error Codes Error Reason UUUUUU 1. Overload 2. Wrong connection with load cell 3. Load cell has quality problem nnnnnnn 1. Calibration is no good 2. Wrong connection with load cell 3. Load cell has quality problem ERR1 ERR2 During calibration, weight is not used or the weight is above the max.
