4.3.2 DC Voltages up to 30 kV with High Voltage Probe HV 30
Voltages of greater than 600 V can be measured with a high-voltage
measuring probe, for example the HV3 (up to 3 kV) of the HV30 (up to
30 kV, DC only) from GMC-I Messtechnik GmbH
➭
Set the range switch to position 30 V , 100 V or 300 V .
Additional error in indication < 6 % of the full scale value. Furthermore,
class 5 applies to the instrument as it is used as current measuring
instrument with 30, 100 and 300 V for the full scale value (chapter 5,
footnote 1) in the voltage measuring ranges 3, 10 and 30 µA.
Attention!
!
For safety reasons, observe the following when measuring
voltages above 600 V to earth:
Put the multimeter onto an insulated surface and connect the
measuring leads in such a way that the protective lead of the
probe and the „
“ socket are directly taken to the protective
conductor (earth) potential. The bonding terminal must be
grounded for this purpose. First, set the range switch to one
of the positions indicated above, and only then turn on the
voltage and scan with the probe respectively.
Do not touch the instrument when the voltage to be measured is
applied!
