Wrist strap tester
The wrist strap tester is used to inspect all types of wired wrist straps for a given range of resistance. The test primarily examines the continuity between the operator, the wrist strap and the exit ground;
The tester is easy to use, simple to operate, fast in test response, supports 9V dry battery and 9V power adapter. The test voltage is DC 9V, the power consumption is extremely low, and there is no damage to the human body.
Features:
1. Can detect various types of wired wrist straps;
2. There is an alarm when the LED is displayed and the FAIL is tested.
3. It is powered by 9V power adapter or 9V dry battery. It is low voltage safe and has automatic undervoltage alarm function.
Operating specification
1. Put on the wrist strap and keep the wrist strap in good contact with the human body. Insert the wrist strap plug into the tester wrist strap jack;
2. Press and hold the "PUSH ON" button to test;
3. The green “PASS” LED indicates that the wrist strap is functioning properly; the red “LO” LED indicates that the resistance of the wrist strap after passing the wrist is lower than the lower limit of 750K, which may be a short circuit; the yellow “HI” LED indicates that the wrist strap passes the wrist. The resistance value is higher than the upper limit of 10M. When the above test fails, the tester should immediately check whether the wrist strap is well worn and retest. If the test is still unqualified, the wrist strap should be replaced and retested.
note:
1. When testing by pressing the test button, the test state should be maintained until the test is completed (time less than 1.0 second);
2. During the test, there may be a phenomenon that the “LO” LED is lit first and accompanied by an alarm sound. This is normal, and the result is based on the last stable and continuously lit LED;
