Prompts of operating technologies
2.1. During operation, align with the front LED of the product (the distance is not more than 1m), press the unlock key at first, then press the corresponding functional keys to set, and the red light flashes when the key is pressed.

2.2. During zeroing setting, the calibration plate should be much larger than the detection window of sensor, and the polar plate and sensor should be well grounded.  

2.3. During the calibration operation, the calibration plate should be much larger than the detection window of sensor and the sensor should be well grounded.

2.4. There should be no shield between the sensor and the detected object; otherwise the accuracy of the detection result will be affected.

2.5. There should be no electrical equipment that may affect the sensor within the detection range of the sensor.

2.6. To accurately measure the charged object, the plane of the sensor detection window must be parallel to the surface of the detected object.

2.7. When the charged object is smaller than the calibration plate, the measured value will be smaller than the actual electrostatic value of the charged object.

2.8. When the charged object is larger than the calibration plate, the measured value will be larger than the actual electrostatic value of the charged object.

2.9. Do not set zero in electrostatic charge state or in the electrostatic measurement process (non-static calibration process); if zero clearing is made during the electrostatic test, the displayed electrostatic value will be zero.

2.10. Influence of temperature and humidity on electrostatic detection:

The lower the temperature is, the smaller the humidity is, the less water is contained in the space, and the more easily the surrounding object triboelectric and the greater the interference to the electrostatic detection is.

1) The higher the temperature is, the higher the humidity is, the more water is contained in the space, and the more active the movement of water molecules is, which is easy to produce corona or spark discharge to the calibration device and the greater the influence on the uniform electric field generated by the calibration device, the weaker the uniform electric field will be.

2) Under the same humidity, the lower the temperature is, the less water is contained in the space, and the more easily the surrounding object triboelectric and the greater the influence on the electrostatic detection is.

Therefore, during electrostatic calibration/detection, the environmental temperature and humidity should be clearly indicated during calibration/detection.

2.11. Due to the existence of the cosmic rays and micro-radioactive substance in the environment as well as the use of various kinds of electrical equipment, there are inevitably more or less positive and negative irons in the detection space, which may also have certain impact on the detection results.

Operation and precautions
VI. Operation and precautions

1. Instructions for use:

During use, the plane of the sensor electrostatic detection window should be parallel to the surface of the object under test. The detection distance and detection gear should be selected according to the static electricity quantity and the operating environmentof the charged object (i.e. above mentioned standard detection distance: 5mm, 10mm, 25mm, 50mm, 100mm, 150mm, 200mm, 250mm, 300mm, 350mm, 400mm, 450mm, 500mm, 550mm, 600mm, 700mm); at this point, the detection data displayed by the terminal is the most accurate.

2. On-line mode: (Monitoring terminal, integrated power supply and communication software need to be purchased additionally)

For the power output network port, monitoring terminal network port and electrostatic sensor network port of 24V power adapter, the network ports of the three devices are both the power port and the communication port, and the network ports of the three devices can be commonly used.
