Sartorius balance display does not show whether the 1.220V power supply is normal, whether the balance power transformer is normal (no load about 18V) and whether the DC power plug is plugged in with the balance.
2. When the balance is connected to a PC or other peripheral, the special RS232 cable provided by Sartorius is not used, causing the CPU on the main circuit of the balance to be destroyed.
3. Display or circuit issues.
2) Unstable, poor repeatability, no return to zero 1. The electronic balance is not warmed up enough.
2. Balance room temperature, humidity is unstable, there is airflow.
3. The weighed sample or sample container itself has temperature and humidity changes.
4. The weighed sample or sample container itself contains magnetic material or static electricity.
5. There is a dry squeezing in the windshield of the balance, which causes changes in humidity, and the air is dried to a certain degree to generate static electricity.
6. There are strong magnetic fields or strong interference signals around the electronic balance.
7. The scale has foreign objects underneath the scale and the tip or scale.
8. The balance plate is not properly installed, or the scale plate is in contact with the shield ring due to improper installation of the balance cover and the draft shield.
9. Load cell problems.
10. Circuit problem.
3) Balance cannot perform internal calibration The balance does not have this function. (eg BS series balances)
2. The balance operation menu is not set to 193.
3. The balance is unstable.
4. The balance put a certain weight on the plate. Or balance weights did not lift up.
5. Calibration zero offset, recalibration.
4) Balance cannot perform outside school The balance operation menu is not set to 191.
2. The balance is unstable.
3. The balance put a certain weight on the plate.
4. Calibration zero offset, recalibration.
5) Linear excess error The corner error is too large.
2. Recalibrate the linearity.
3. Load cell problems.
6) Balance error over tolerance No adjustment to the balance level.
2. Re-adjust the corner error.
3. Load cell problems.
7) The boot shows "H"
1. Load cell problems.
2. Circuit problem.
8) Display "H" when weighing
1. Weigh the weight beyond the maximum allowable weight of the balance.
2. The preload value is out of tolerance and readjust.
3. The balance weights with internal school function have not been lifted.
4. Electronic zero offset, readjust.
9) Display "L"
1. Did not put the plate.
2. If the weight of the maximum weighing value still shows "L", it is basically a load cell problem or a circuit problem.
3. If you gradually put weights on the balance until the "L" can disappear, the load cell basically has no problem. Recalibrate the calibration zero.
10) The upper left corner of the balance shows ""The number has not been displayed for a long time.
The balance is very unstable, probably with the fault 2
11) Power on display "
1"
The balance is first self-tested when it is turned on, and since the TEAR key is normally closed, the menu setting is entered. Replace the peel button.
12) The digital balance operation menu is set to 114 after about 20 seconds after power on.
13) Always display "zero" when weighing articles that are close to the balance's minimum reading (d value).
The balance operation menu is set to 161 and the automatic zero return function is switched on.
14) After the balance school is completed, it is not allowed to change the weight value of the inner school due to the temperature change or the wear of the internal school. Rewrite the internal school weight value.
15) It is not possible to change the balance operation menu. The balance operation menu switch is not turned on.
2. After changing the menu code, it is not confirmed or stored.
16) The internal school motor rotates after the balance is turned on. The internal school motor control switch is misplaced and readjusted.
2. Circuit problem.
17) After the balance is powered on, it is said to vibrate. The power supply is unstable.
2. Zero indicator is not adjusted properly.
3. Circuit problem.
18) There is no reaction or very little reaction when the balance is weighed. The gold wire connecting the sensor coil is broken.
2. Sensor coil short circuit.
3. Circuit problem.
19) All balance buttons fail. The button panel is connected to the public ground.
2. Button panel aging. (Old balance)
3. Circuit problem.
20) The YDP03-OCE Printer does not print or print the word clearly. The rechargeable battery is dead or the battery capacity is not enough (less than 500mah).
2. Change the ribbon.
21) The YDP03-OCE printer cannot charge the battery. The balance is not in the standby state.
22) The balance does not communicate with the PC (press the print key to display Err30)
1. There is a problem with the cable connecting the balance to the PC.
2. The balance is in the BPI interface mode and must be set to the SBI interface mode (set menu code 9-1).
3. The interface parameters of the balance and the PC are not set correctly.
