A3870 – STATOR AND ROTOR TESTER (factory code A3470)
General: The A3870 is a reliable and handy test instrument for quality assurance and fault location in electric motors. Both short-circuits and interruptions of coil windings can be rapidly detected. The A3870 tester appears as a hand-held cylinder that contains the testing arrangement. The tester consists of two coils, an electronic AC signal generator and a detector/driver for Led indicators. The electronics are contained in the handle of the instrument, while the coils are mounted at the sensing end of the unit.
A Test and Calibration tool is for a rapid verification of the operation of the tester and for calibration is also supplied. A trimmer is accessible through a hole in the handle of the tester and may be used to adjust the red/green switchover point. The unit is power-supplied by a separate power pack, operated at 220V, 50Hz (other values on request). The A3870 comes complete extensive instructions manual
