A. Use
The one 9V battery into the battery compartment on the back of the tester;
The ground wire banana plug into the ground jack tak-498 tester upper end;
The wrist strap fastened;
The ground wire connection handbags;
Press the test plates by hand. In this case， the liquid crystal display lights up and you hear a sound.
      1) If the green "GOOD" light is lit， a good grounding system;
      2) If the red "LOW" light is on， the hand should be checked with a grounding wire resistance， because it may have an impact on the human body is lower than 800KΩ;
      3) If the red "HIGH" lights shall check that the strap is fastened wrist strap and check the grounding wire resistance， make sure the strap is not loose ground wire tester.
Two: Specification
Indicating the calibration impedance buzzer
Low (red) R <800KΩ OFF
Good (green) 800KΩ≤R≤9MΩ ON
High (red) R> 9MΩ OFF
Features:
● accurately， quickly and easily detect the grounding system meets the standards.
● wrist and ground impedance contact between the skin of the wrist strap， anti-static board， anti-
Electric mat and grounding lines.
● at any place quickly and easily check a variety of grounding systems to ensure their safety.
● eliminate damage caused by static electricity products.
Specifications:
Check the resistance indicator
Low (LOW): resistance is less than 800 kilohms
Normal (GOOD): 800 kilohms ≤R≤9 megohms
High (HIGH): resistance is greater than 9 megohms
