5.6 Capacitance Measurement
(METRAHIT⏐X-
TRA⏐OUTDOOR and METRAHIT⏐TECH only)
Ð Disconnect supply power from the electrical circuit of the
device to be measured, and discharge all high-voltage
capacitors.
Ð Make sure that the device under test is voltage-free.
Capacitors must always be discharged before measurement is
performed.
Interference voltages distort measurement results!
Refer to chapter 5.1.1 regarding testing for the absence of
voltage with the help of the direct voltage measurement.
Ð Set the rotary switch to “ ”.
Ð Connect the (discharged!) device under test to the sockets
with the measurement cables as shown.
Note
The “–” pole of polarized capacitors must be connected to
the “⊥” jack.
Resistors and semiconductor paths connected in parallel to
the capacitor distort measurement results!
