Symptom | Possible Causes | Solution |
blank display when On/Offis pressed | discharged battery | replace battery |
defective battery | ||
defective ON/OFF key | press ON/OFF key for long | |
no action taken after TARE or HOLD is pressed | defective TARE or HOLD key | clean TARE or HOLD key |
unstable readings | scale in motion | stabilize the load and scale |
scale in damped | dry the scale | |
dust on PCS board | clean PCB board | |
reading is not zero without load | unstable system power | longer warm-up time |
load-cell stressed too much or too long | hang the scale in storage | |
large error in weight reading | scale is not zeroed before loading | keep the scale unload and reboot |
re-calibration nee ded | re-calibration the scale | |
improper unit | switch to proper unit |
