Measuring Capacitance And Cable Length In Km - Gossen MetraWatt METRAHIT ENERGY TRMS System Multimeter Operating Instructions Manual

5.6 Measuring Capacitance
Ð Disconnect supply power from the electrical circuit of the de-
vice to be measured, and discharge all high-voltage capaci-
tors.
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 section 5.1.1 regarding testing for the absence of volt-
age 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!
Note
Use of the power pack may result in significant deviations
during capacitance and cable length measurements!
Note
This function is above all intended for the measurement of
components. For telecommunication systems, it's advisable
to use the special capacitance measurement for measure-
ments in symmetrical copper cable networks with the
