Voltage tester TKF-12

phase sequenceACphase

Phase Sequence Tester The TKF-12 tester is a modern high-quality, simple and safe device. However it is recommended to get acquainted with he present manual in order to avoid measuring errors and prevent possible problems related to operation of the meter. 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. Power supply from the tested network (continuous operation to 15 minutes for max. voltage). Protection against faulty indication of field rotation. Electric security: type of insulation: double, according to EN 61010 - 1 measurement category: CAT III 600 V acc. to EN 61010 - 1 protection class acc. to EN 60529: IP42
