LDY-TEST108B surge protector tester instructions
Safety attention
1. During the test, the voltage will rise above 1000V, and the maximum current is 1mA. Do not touch the bare part of the test pen during the test.
2. Do not press the test button without the sample to avoid damage to the tester.
3. In the case of standby prompt, please turn off the power in time.
4. Please strictly follow the operation steps for testing and calibration. Non-professionals should conduct calibration test or open the tester under professional guidance.
Tester power supply
There are two ways to supply power:
1. Connect the 5V 2.5ADC external power supply, plug in the power supply, and the screen displays the initial value of "0", which is the standby state.
2. Load 4 No. 5 ordinary batteries or rechargeable batteries. After loading the battery, press the red button on the side to turn on the battery power switch. The screen first displays the voltage of the battery, then displays the initial value of "0", which is the standby state.
3. If the voltage is lower than 4.5V, "LOBAT" will be displayed in the upper left corner of the screen to indicate low voltage.
4. When the standby time exceeds 300 seconds (300 seconds per interval), the tester emits a continuous “drip†to remind the power to shut down and save energy, so as to avoid running out of battery.
Test error
If the error is considered to be in an unacceptable range, it is recommended to calibrate to the common voltage segment and critical leakage current. For example, the calibration for the 300V voltage segment is performed at a voltage of 500V, which will produce a larger error.
Use of banana plugs and test pens
1. There are two test pen jacks on the top of the tester. Insert the red and black test pens into the corresponding color jacks.
2. The other end of the test pen is sheathed or pin-type test head according to the test requirements. (The following test method uses the clip type as an example to test the lightning protection module without the base)
3. Prepare the lightning arrester to be tested
4. Clamp the poles of the arrester with the test clip
LDY-TEST108B surge protector tester test preparation, select sample type
1. Set the type of lightning arrester to be tested (Note: A gear is a voltage limiting type lightning arrester, such as MOV, B gear is a switch type lightning arrester, such as GDT, N-PE module)
2. The limited-pressure type tested products take the module of WTH-40/C/1P-385 as an example.
3. The switch type test object takes the WTH-65/G-255 module as an example.
