Measuring range Frequency range

2 V, 20 V

750 V
Maximum resolution: 1 µV within the 20 mV measuring range
* In the frequency range 5 kHz ~ 50 kHz 20 digits must be added to the speci-
1
fied measuring range limit value - for display values less than 50 % of the
measuring range limit value.
Within a frequency range of 50 kHz ~ 100 kHz, display values less than
40 % of the measuring range limit value are not specified.
7.3 Direct current ranges (Switch setting: A DC, mA DC)
overload protection:
- F 1 A (600 V) fuse, 10 kA, (Bussmann BBS-1 or equivalent) on the mA
input,
- F 15 A (600 V) fuse, 100 kA, (Bussmann KLK-15 or equivalent) 10 A on the
input,

7.4 Alternating current ranges (Switch setting: A AC, mA AC)
The measured value is obtained and displayed as a real effective value (TRUE
RMS).
Selectable coupling type: AC or AC+DC. For the coupling AC+DC an additional
error of 1 % + 80 Digit must be taken into account. In the case of non-sinus-
shaped curves the display value becomes less precise. Thus an additional error
results for the following crest factors:
Crest factor from 1.4 to 3.0 additional errors + 1.5 %
Crest factor from 3.0 to 4.0 additional errors + 3.0 %
Overload protection:
- F 1 A (600 V)-fuse, 10 kA, (Bussmann BBS-1 or equivalent) on the mA
input,
- F 15 A (600 V)-fuse, 100 kA, (Bussmann KLK-15 or equivalent) 10 A on the
input,
