Connect the probe to the motor to check the winding resistance from phase to phase. So like the multimeter a megger would also have a rotary selector so turn it to Ohms and after that check, the leads and this will be checking electrical continuity. Test time: About 60 ms (3000 V, 1 pulse, reference value at decision OFF) The first step would be checking the winding resistance.Number of test condition tables: 255 (test condition setting, judgment condition setting, master waveform).RC value judgment, waveform judgment, discharge judgment (when incorporating the ST9000).Voltage detection accuracy: ± 5% of setting, 100 kHz: ± 1 dB Basic Motor Testing Parameters and Tools: Primary Analysis There’s a huge range of diagnostic tools available for pinpointing motor issues clamp-on ammeters, temperature sensors, Meggers, winding analyzers and oscilloscopes, just to name a few.Sampling: 200 M / 100 M / 50 M / 20 M / 10 MHz, Resolution: 12 bits, Number of data: 1001 to 800 points (1000 point steps).
Testable inductance range: 10 μH to 100 mH.
100 V to 3300 V (Setting resolution: 10 V steps).
