Instructions for Use

1. Power on: Press the "On/Off" button to turn on the device and enter the measurement interface. (As shown in the figure)

2. Measurement: The crocodile clip of the reading instrument is connected to the core wire of the sensor. If the connection is reliable, the measured frequency, modulus, and temperature can be displayed. The connection wire of the reading instrument is a three color core wire, where "black" is a common wire (black and red frequency; black and white temperature and coding). When connecting, please match the three different colored crocodile clips of the reading instrument connection wire with the color of the sensor wire core wire to measure the measurement value. In general, the red and black wire colors of the sensor core are frequency or modulus, and the "1" key is the frequency and modulus switching key. The green and white lines are temperature (coding) measurement lines.

3. Background light: When the outdoor light is strong, the background light function can be used, which can be switched by pressing the "2" key.

4. Shutdown: Press the "on/off" button again to enter the shutdown state

Safe use and maintenance

The reading instrument adopts embedded control technology, and most of the control functions are implemented by software programming, so there is less maintenance and adjustment work. However, the following issues still need to be paid attention to by users during use:

1. Do not press the film button forcefully during use to prevent hard objects from damaging the display screen. When not in use, it should be stored in a dry and ventilated room.

2. During transportation, shock-absorbing objects should be placed around and not thrown or dropped.

3. Pay attention to the positive and negative polarity of the battery when replacing it (it is recommended to send it back to the original factory for replacement).

4. If the instrument is not used for a long time, the battery should be removed and stored in a dry place.

5. When using the reading instrument, the panel should be kept clean and there should be no liquid or debris sliding into the interior of the panel, which may cause electronic components to malfunction. Be careful when wiping.

Frequently Asked Questions and Answers

1. The reading instrument cannot be turned on normally

------It is possible that the battery is low, please check if the battery is charged

2. The reading instrument cannot measure values normally

------Firstly, check if the connection between the measuring terminal and the sensor is reliable. If the connection is normal, please replace the sensor before measuring; If it still cannot be displayed normally, please inquire with the manufacturer or send it back to the original factory for testing and repair.

3. The reading value of the reading instrument is unstable

------The working voltage of the reading instrument is too low, which may cause unstable measurement readings. Please charge it in time.

------It is also possible that the sensor is not working properly. Please replace the sensor before testing.
