Wrist strap tester
The wrist strap tester is used to test all types of wired wrist straps within a given resistance range. The test mainly tests the continuity between the operator, the wrist strap and the outlet ground wire. This tester is easy to use, simple to operate, has a fast test response speed, supports two power input methods: 9V dry battery and 9V power adapter, and the test voltage is DC 9V. The power consumption is extremely low and there is no harm to the human body.

Operation specifications
1. Wear the wrist strap and keep it in good contact with the human body, and insert the wrist strap plug into the wrist strap jack of the tester;
2. Press and hold the "PUSH ON" key to test;
3. The green "PASS" LED is on, indicating that the wrist strap functions normally; the red "LO" LED is on, indicating that the resistance of the wrist strap after passing through the wrist is lower than the lower limit of 750K, which may be a short circuit; the yellow "HI" LED is on, indicating that the resistance of the wrist strap after passing through the wrist is higher than the upper limit of 10M. If the above test fails, the tester should immediately check whether the wrist strap is worn well and retest. If the test still fails, the wrist strap should be replaced and retested.
Note: 1. When pressing the test button to test, the test state should be maintained until the test is completed (time is less than 1.0 second);
2. During the test, the "LO" LED may light up first and be accompanied by an alarm sound. This is normal. The result is based on the last stable and continuously lit LED;
