· Adapter is bad

·Host panel is bad

·Power on

·Press the < Start > button

·Re-switch the balance or re-plug the power cord

·Change adapter

·Change the host panel

2

Only show "     Upper line segment

· exceed the maximum load

· Internal memory calibration number is destroyed

·The weighing plate is not installed

· Should reduce the load immediately

• Recalibrate in the order of “Calibration Balance” above. After the standard weight is put on, it takes about 8 seconds to stabilize and then display the calibration result.

·Reinstall the weighing plate

3

Only show "     ” Lower line segment

·The weighing plate is not installed

·Not put on the weighing pan and not light

·Limited screw loose

·Reinstall the weighing pan

·Check sensor

4

Weighing display value is unstable (data jitter)

·Airflow

·Worktable instability

·The balance time is short

·The balance is very volatile at room temperature

·Close the balance windproof door

·The balance is placed on a stable workbench

· Optional longer integration time

·Control room temperature

5

Weighing results are not accurate

·Not cleared before weighing

·The balance is not calibrated or the calibration weight is not accurate

·The power supply voltage is incorrect

·Press the < Tare > button

· Balance recalibration

· Use the correct power supply

·Check the four-corner error (whether it is within the qualified range)

6

The display stays at a certain digit or a meaningless symbol appears

·The outside world has instantaneous interference

·The power supply voltage is incorrect

·Reboot or re-plug the power

· Use the correct power supply

7

The stable mark “ 0 ” on the left side of the display does not go out.

·The balance is more sensitive

·The environment in which the balance is not ideal (such as large airflow, vibration, room temperature fluctuations, etc.)

·Reselect a stable one

· Should change the environment

8

Always show wait state "--"

·The environment in which the balance is not ideal (such as large airflow, vibration, room temperature fluctuations, etc.)

·The balance is too sensitive

· Should change the environment

·Selectable sensitivity third gear

9

Display " Err--1 " or " Err - 2 "

· Instantaneous interference

·The balance is faulty

·Reboot or re-plug the power

· Send inspection unit, inspection, module or 93C46 or 16V8D

10

Show " CAL " or "Err"

· Before the balance is calibrated, objects are left on the weighing pan

·The calibration weight is incorrect

·Not cleared before calibration balance

· Press the calibration button without displaying the weighing mode

· Take the object, clear the calibration

· Calibrate with accurate calibration weights

· Clear calibration

·Go to weighing mode

11

The weighing unit on the far right of the display is not displayed.

·The balance is not calibrated

·The calibration data of the internal memory of the balance is washed away

·The balance needs to be calibrated

·Ibid.

·Sensor damage

12

Show " Cou--Err "

· No preset constants during point operation

·Weigh too much when preset over constant

·The weighing is too small when the preset is over constant

· Preset operation for the average of points

·The balance needs to be calibrated

13

Do not show
