BM877

BM877 is the new generation 3 in 1: superior multimeter, insulation tester and earty continuity tester. Helps to determine the state of insulation material and earth continuity for preventive maintenence. Offers five test voltages: 50, 100, 250, 500 and 1000V for insulation, PI (Polarization Index) @ DAR (Dielectric Absorption Ratio), PASS/FAIL Insulation Compare Feature,  as well as 200mA high current test for earth continuity. Convenient remote probe, test inhibits on live circuits, lock feature for continuous testing.

Unique functions:

PI (Polarization Index) – diagnostic test for electrical insulation, calculating the ratio of insulation resistance

DAR (Polarization Index) – diagnostic test used to quickly assess the condition of electrical equipment

Beep-Jack™ – beeps against improper terminal plug in (decreases risk of damage)

VFD V & Hz – Variable Frequency Drives – measures fundamental voltage and frequency of most variable frequency drives

REC – recording MAX, MIN, MAX-MIN & AVG

Smooth mode – smooth out unstable insulation resistance reading

Hz of line voltage – measures noisy high voltages ACV frequencies in dual display
