The TEK200 can detect the presence of voltage and magnetic fields produced by indicators, relays, solenoids and transformers.

The integral self-test activates the sensor in the tip of the tester at 50Hz as well as checking the battery and LED and sounds the buzzer intermittently to indicate correct operation. This proves that the unit is fully functional and avoids the need for a separate proving unit.

The instrument is then ready to detect voltages from 100V to 600VAC or magnetic fields on solenoids or relays.

This versatile instrument is housed in a slim and ergonomic ABS housing.
