Care and maintenance To keep the balance operating properly, the housing and platform should be kept clean and free from foreign material. If necessary, a
3、 cloth dampened with a mild detergent may be used. Keep calibration masses in a safe dry place.Unplug the AC Adapter when not in use. For long term storage, remove the batteries.6. Error Codes The following list describes the various errors which may appear on the display and the suggested remedy. D
4、isplay descriptionErr 0 With the platform on, this signal indicates the platform is too light. Make it heavier properly. 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 exceeds t
5、he capacity of the balance. If the error occurs when the sample is within the balance capacity, maybe the balance is not correctly calibrated.41.DescriptionES-HA series electronic balances do weighing and measuring with high precision loadcell, microcomputer and big liquid crystal display screen. It
6、 has the advantage of simple operation, speedy weighing, accuracy, stability, and so on. 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.

9、at the bottom of the balance (pay attention to the Plus(+) and minus(-) ends).With no load on the platform, press . 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 offTo turn off the balance, press while the
10、balance is at work.4.3 Weighing methodPress to set the display to zero. Put the object to be weighted on the platform. Wait until the unit “g” appears and the reading is stable, then the weight can be read.4.4 Balance calibrationWhen precision weighing is done, calibrate the balance as follows:First
11、 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 interchangeable.)4.4
12、.1 Sensitivity calibrationWhen 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“. In a few secon
13、ds, 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, indicating that cali
14、bration 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
15、 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 corresponding calibrating weight on the center of the platform. In a few seconds, the display will stop, and meanwhile the calibrating weight value will be
16、shown, indicating that calibration is over. Normal weighing can be done.2NOTE: The balance linear has been calibrated in the factory, unless the users need to change the loadcell or have the right weight.Mode ES-120HA ES-200HA ES-300HA ES-400HA ES-500HA ES-600HA ES-1000HACal.

To get
18、 more accurate counting result, the weight of the parts should be equal, meaning the less the error of the single part is , the better.(1) Press , the balance will display “pc CON”.(2) Place a container on the platform, then press the balance displays “pc ADD 5” which is the preset reference quantit
19、y. “5” shows the quantity of the reference sample.(3) To change the reference quantity, press repeatedly until the desired quantity is displayed. Press to make sure the quantity of the reference sample.NOTE: If you want to restart parts counting, repeat the operation steps above. If “PC Err” is disp
20、layed, it means the sample is too light to provide accurate results within the error range set by the balance.(4) Add parts to the container as desired and read the quantity on the display. At this time, only “pc” counting signal is displayed (“g” is not displayed.).(5) Press to switch between parts
