HV Probes Adjustment
The adjustment process writes and saves the new calibration constants. For each
recommended high voltage probe, the calibration menu contains two independent constants.
For 40 kV probe 80k-40:
40 kV probe ratio
xxxx.x (-)
DC divider coefficient with connected load
10 M
Ω
/0.1%
40 kV probe ac-dc deviation
x.xx (-)
AC/DC difference of divider ratio between dc
and 55 Hz
For 10 kV probe 190-06:
10 kV probe ratio
xxxx.x (-)
DC divider coefficient with connected load
10 M
Ω
/0.1%
10 kV probe ac-dc deviation
x.xx (-)
AC/DC difference of divider ratio between dc
and 55 Hz
To make this adjustment:
1. Select
HV Probes
from calibration menu.
2. Select the required parameter to change.
3. Use the cursor buttons or rotary knob to adjust the value.
4. Push the
Write
softkey to save the value.
Note
The ac/dc difference parameter is mostly created by the mechanical design of the
probes. Fluke Calibration recommends to not change the original constant, if a new
constant is not known with uncertainty better than 0.1 %.
Note
The dc divider coefficient is created by a number that represents 1/p, where p is probe
dividing ratio. The coefficient nominal value is 1000.0.
