How are the various quantities measured? (continued)
9. Measurement on an
MLI type speed
variator
Voltage measurement
1. Set the switch to
.
2. Select the filter by pressing
.
3. Connect the black lead to the “COM” terminal and the red lead to “
+
”.
4. Place the test probes between two phases of the circuit to be measured:
5. Read the measurement values indicated on the display unit (voltage and
frequency):
“
O.L
” is displayed above 1050V and a beep sounds when the
measurement exceeds 600V.
The presence of the symbol indicates that the filter is active.
Remark: It is very important to leave the filter activated to measure the
voltage and frequency of the signal without being perturbed by
the MLI.
