Common questions on this part
Polarization Index is the ratio of insulation resistance measured at 10 minutes compared to 1 minute (R10min / R1min). A PI ratio above 2.0 indicates clean, dry, and healthy motor winding insulation, whereas a PI below 1.5 indicates moisture contamination or insulation deterioration requiring drying or rewinding.
Yes. When the test button is released, the BLX-MEG-5700 automatically switches to an internal rapid discharge resistor, safely discharging all capacitive charge stored in the cable or motor windings while displaying the falling residual voltage.
For standard 415V 3-phase industrial motors, IEEE 43 guidelines recommend using a test voltage of 1000V DC. Higher voltages (2500V or 5000V) are used for medium/high voltage equipment (3.3kV and 11kV).
Yes. Every BLX-MEG-5700 tester is supplied with a factory test report and certificate of calibration traceable to national standards.
Yes. STARNEX provides local warranty support, technical guidance, and complete accessories at our Nairobi service hub.
