Why OHAUS EC not turning on?
Your OHAUS scale might not be turning on because the AC power is not connected. Ensure that the scale is properly connected to a power source. Alternatively, the battery may be discharged. In this case, connect the scale to a power source to charge the battery.
What to do if my OHAUS EC Scales won't turn on with the AC adapter?
If your scale isn't turning on with the AC adapter, the adapter itself, the membrane switch, or the main PC board could be defective. First check the AC adapter voltage output. If the voltage is low or nonexistent, replace the AC adapter. If the adapter is OK, test the membrane switch and replace if necessary. If the scale still fails to turn on, the main PC board should be tested and replaced if defective.
Why OHAUS Scales can be turned on but will not calibrate?
If your scale turns on but won't calibrate, the issue might be incorrect weights, a defective load cell assembly, or a defective main PC board. First, verify that you're using the correct weights. If so, test the load cell and replace it if defective. If the problem continues, the main PC board should be tested and replaced if defective.
What to do if OHAUS EC Scales does not display accurately?
If your OHAUS scale isn't displaying weight accurately, it might be due to improper calibration. Calibrate the scale using the correct calibration weights to resolve this issue.
What to do if OHAUS EC Scales weight reading does not stabilize?
If the weight reading on your OHAUS scale is unstable, it could be due to an unstable environment. Make sure the scale is placed in a stable location. Another potential cause is interference under the pan. Ensure that the weighing pan is unobstructed and free to move.
Why does my OHAUS EC read incorrectly or display unstable readings?
Incorrect readings or unstable balance can be caused by a few things. First, the scales may need calibration. Second, the load cell could be damaged. Third, the main PC board may be defective. You can try to solve this by performing a service calibration. If that doesn't work, test the load cell. If it's defective, replace it. If the issue persists, the main PC board should be tested and replaced if found defective.
What does --OL-- displayed mean on OHAUS EC?
If your OHAUS scale displays '--OL--', it means the load on the pan exceeds the scale's capacity. Reduce the weight on the pan to resolve this.
What does E1, E2, E3 displayed mean on OHAUS EC Scales?
If your OHAUS scale is displaying 'E1, E2, E3', it could be due to the pan being incorrectly positioned. Reposition the pan correctly. It may also indicate that the zero limit was exceeded during power up. Make sure the pan is empty before switching the scale on.
What to do if OHAUS EC Scales does not respond to front panel controls?
If your scale isn't responding to the front panel controls, the membrane switch may be defective. Test the membrane switch and replace it if necessary. If the membrane switch is OK, test the Main PC Board. If it's defective, replace the Main PC Board.
What causes the display to fail on OHAUS Scales (not on or partial characters)?
A display that is not on or showing partial characters indicates that the display PC board is defective or the LCD may be defective. Verify that other problems do not exist first. Test the LCD Display. Replace Display PC Board or LCD.
