1. No display after startup.

Check whether the socket of the power supply is electric.

Check whether the plug of the counting machine is inserted.

Check whether the fuse of the counting machine has been fused.

2. Failure prompt code after startup.

In general, the counting machine has the function of failure self-check.

Different counting machine, the fault code is different. Please refer to the instruction manual.

3. Inaccurate counting

Adjust the vertical screw at the back of the tray, and screw clockwise for a week or two.

To clean up the dust (dust removal) on the photoelectric counting sensor.

After the dust can not return to normal, the resistance eraser, the twisting wheel is serious wear. Adjust after the change.

To adjust the position of the photoelectric counter sensor.

4. The fluorescence detector does not alarm or detect false sensitivity.

The sensitivity button of the circuit board and the sensitivity of the modulator (the sensitivity of the fluorescence detector)

Fluorescent lamp tube light sensor (fluorescent lamp probe) is dust collecting.

Whether the fluorescent tube is old or not.

5. The start-stop mode fails.

Whether or not the sensor collects dust.

The feed sensor and the main circuit board are connected to open the road, then can be connected.

The belt of the counting machine is broken.
