5.8. MEASUREMENT OF DC, AC, AC+DC, INRUSH CURRENT WITH CLAMP
TRANSDUCERS
CAUTION
Maximum measurable current in this function is 3000A AC or 1000A DC.
Do not measure currents exceeding the limits given in this manual.
The instrument carries out the measurement both with flexible clamp
transducers (optional accessories) and with other standard clamp
transducers in the HT family (optional accessories). With transducers
having an Hypertac output connector, the optional adapter NOCANBA is
necessary to obtain the connection.
Fig. 36: Use of the instrument for current measurement with clamp transducer
1. Select the position.
2. Press key MODE/MXMNPK to select the type of clamp transducer among the options:
“ ” (flexible clamp transducer – only AC) or “ ” (standard clamp transducer – AC or DC).
3. Press keys / or and, on the instrument, select the same range set on the
clamp, among the options: 30A, 300A, 3000A (AC current measurement with flexible
clamp) or: 1A, 10A, 30A, 40A, 100A, 200A, 300A, 400A, 1000A, 2000A, 3000A for
AC, DC, AC+DC current measurement with standard clamp).
4. For flexible clamp transducers, set the relevant full scale value of voltage (see §
4.2.10).
5. Press key GO/HOLD to confirm settings.
