Martindale Part No: MARTEK200
Detects the presence and polarity of 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. This proves that the unit is fully functional and avoids the need for a separate proving unit.
In addition, this unit incorporates all the capability of the TEK100 voltage indicator detailed above, producing a versatile instrument in a slim and ergonomic ABS housing.
