A.C. Voltage Measurement (BM100/4 only):
The Voltage range is automatically selected when the switch is in any
position and the 'Test' push button is not pressed. When connected across
the circuit under test, the BM100/4 will indicate if the circuit is energised
(a.c. or d.c.), and measure a.c.voltage up to 600 V.
Voltmeter Input Impedance:
Automatic Discharge:
discharged via an internal (<500kΩ) resistor, when the 'Test' push button
is released following an insulation test.
Accuracy (at 20°C):
on Insulation range). Insulation range is marked with a white band (Class
1,5 as VDE 0413). Other ranges are Class 3.

Temperature Range: Operation: -5°C to + 40°C
