Ji Ming electronic balance error Diagnostics:

Appear low line causes: balance weight on the negative. Treatment: using weights to calibrate

Upper line causes: overweight alarm management: using weights to calibrate

Err-1 reason: continuous switch cause: shut down for three seconds and then boot

Err-2 reason: weighing is not stable: wait a minute

Ji Ming calibration method of electronic balance:

Single point calibration: in cases, without any object on the scales, press the CAL Calibration key does not let go, and about the 3Seconds after '-CAL -' Let go immediately when, later on, shining standard weight values are displayed, will shine weights placed weight on the scales show '----' wait state, later on, standard weight value displayed, take the weight, showed '----' wait state, later on, display 0.0Or 0.01Or 0.001, End of calibration. Calibrated weighing is not accurate, calibrated according to the above process is repeated several times.

Multiple-point calibration: in cases, without any object on the scales, press the CAL Calibration key does not let go, and about the 3Seconds after '-CAL -' Let go immediately when, later on, shining standard weight values are displayed, and then press 'COU Or PCS Keys ', CA 2Seconds after a standard weight values, standard weight value will be displayed second place weight on the scales, displays '----' standby display standard weight value, take the weight, showed '----' wait state, shown later 0.0Or 0.01Or 0.001, End of calibration.
