Error Codes The following list describes the various errors which may appear on the display and the suggested r

If this error still occurs, the sensor or the circuit board may be destroyed. The balance must be sent to the manufacturer to be serviced. Err 1 The sample being weighed
5、exceeds the capacity of the balance. If the error occurs when the sample is within the balance capacity, maybe the balance is not correctly calibrated.41.Description ES-HA series electronic balances do weighing and measuring with high precision loadcell, microcomputer and big liquid crystal display

It is widely used in factories, mines, institutions, agricultures, traffic, building, water conservancy, medicine, food, and so on. Its more applicable in business for weighing precious products. 2.

All the segments of the display will be shown, then the software version is displayed. When “0” is displayed, weighing can be done. 4.2 Turn off To turn off the balance, press wh

Wait until the unit “g” appears and the reading is stable, then the weight can be read.4.4 Balance calibration When precision weighing is done, calibrate the balance as fo
11、llows: First take away the object from the platform, then press to set the display to zero. Press , displaying “SCALE” or “LINE”. “SCALE” means calibrating the balance sensitivity; “LINE” means calibrating the balance linear. Press to make sure (If press , the two kinds of calibration can be interch
12、angeable.)4.4.1 Sensitivity calibration When calibrating the balance sensitivity, two different weight values can be used. According to the shown calibrating weight value, press , the two calibrating weight values can be interchangeable, press to make sure. After that, the balance will display “0“.
13、In a few seconds, the balance will display the calibrating weight value. At this time, put the corresponding calibrating weight on the center of the platform according to the shown weight value. In a few seconds, the display will stop, and meanwhile the calibrating weight value will be shown, indica
14、ting that calibration is over. Normal weighing can be done.4.4.2 Linear calibration Being in the state of “LINE”, press , the balance will display “0”. In a few seconds, the balance will display 1/2 weight value of full capacity; according to the shown weight value, put the corresponding calibrating weight on the center of the platform. In a few seconds, the balance will display the full capacity weight value, according to the shown weight value, put the corr
