Characteristic Values
1) The 100 mV to 10 V measuring ranges can also be used for current measurement
in accordance with the following table (e.g. reverse current or insulation current).
These measuring ranges are rated at accuracy class 5. Frequency range
at
~: 15 ... 100 Hz.
Same overload protection as for voltage measuring ranges.
2) Measured value = displayed value + constant, 0 dB
0.775 V, i.e. 1 mW at
600
3) Protected with PTC resistor
3) Protection by means of FF 1.6A/600V AC fuse link in combination with rectifier
diodes.
4) FF 16A/600V fuse link, 10 A: max. 10 minutes
Accuracy under Reference Conditions per IEC 60051/EN 60051
Class 1.5 for zero-frequency quantities, class 2.5 for periodic
sinusoidal quantities and class 1.5 for resistance (intrinsic error
relative to 69 mm scale length) corresponding to max. 10%
intrinsic error of the measured value within the range of the
exaggerated scale arc.
