MOTOR TESTER
SMT-20
 
 
 
MOTOR TESTER SMT-20 MEASURES :
 
Insulation resistance of winding at 500 VDC/1000 VDC max for detecting leakage between winding to winding or to earth.
Resistance of the windings for detecting the open circuits / loose connections dry solder in a winding coil.
Inductance of the windings for detecting the short circuits between individual turns of a winding coil.
Inductance of the windings with respect to different positions of rotor for detecting blow holes or cracks in the rotorbars.
All these defects can be checked with in a few minutes without dismounting the equipment (after switching off the power supply)
Motor Tester SMT-20 comes with a carry case, test leads and 6 Nos. 1.5 V Cells,Battery Eliminator is an optional accessory.
