• Phase sequence indication (direction of field rotation) in the power network with rated phase-to-phase voltage (120...690 V) AC by LED signalization
• Operation in the power network with frequency range 10...70 Hz
• Indication of the voltage presence in the particular phases by neon lamps signalization

The TKF-12 tester is a modern, high-quality, simple and safe device. However, it is recommended to get acquainted with the present manual in order to avoid measuring errors and prevent possible problems related to the operation of the meter.

The unique TKF-12 & TKF-13 testers has been designed for checking triple phase power installations in the wide range of the phase-phase voltage between 100V to 690V in the distribution network frequency range 10-70Hz. Our testers enable rotary field and motor rotation indication also with contact-less detection. TKF-13 provides quick indication of 3-phase rotation using test leads or can be used to determine motor rotation on 3-phase motors. TKF-12 is powered by a tested network. TKF-13 is powered by a 9V battery with an AUTO-OFF function.
