0 to 500 V
1,0 to 50 V
The instruments meet the requirements for double insulation to IEC 1010-
1 (1995) EN 61010-1 (1995) to Category III*, 300 Volts phase to earth,
440 Volts phase to phase, without the need for separately fused test
leads. If required, fused test leads are available as an optional accessory.
The B M 4 0 2 / 2 and B M 4 0 4 / 2 do not incorporate a voltage range and
must not be intentionally connected to live circuits. *Relates to transient
overvoltage likely to be found in fixed installation wiring.
