Technical Data
1)
T he voltage measuring ranges 100 mV .... 10 V can also be used for current measurements
as shown in the following table (e.g. reverse currents or leak currents). The accuracy of
these measuring ranges then corresponds to class 5.
Frequency range on
~
: 15 ... 100 Hz
Overload protection same as on the voltage measuring ranges.
2)
Measuring value = indicated value + constant ; 0 dB
0.775 V, i.e. 1 mW at 600
3)
protected by PTC thermistor; cooling time of thermistor before the start of next measure-
ment: grant at least 2 minutes.
