BM878 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 as well as 200mA high current test for earth continuity. Convenient remote probe, test inhibits on live circuits, lock feature for continuous testing.
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
X-Speed Capacitance – measures up to 30mF only in few seconds, 1kV protection
Hz of line voltage – measures noisy high voltages ACV frequencies in dual dispaly
Temp – temperature measurement
