13 Capacitance Measurement (METRALINE DM 62 only)
• Verify that the device under test is electrically dead. Exter-
nal voltages would falsify the measured results!
• Set the function selector switch (6) at „ “.
• Connect the (discharged !) device under test to the „ “
and „ “ sockets via test lead.
Note
• Connect polarized capacitors with the „–“ pole to the „ “
socket.
• Resistors and semiconductor junctions in parallel with the
capacitor falsify the measured results!
Zero adjustment on the 6.600 nF measuring range
When measuring small capacitance values on the 6.600 nF
range, the internal resistance of the multimeter and the capaci-
tance of the leads can be eliminated by the „REL“ function.
• Connect the test leads to the multimeter without a device
under test.
• Press and hold the PEAK (2) key and press the AUTO/MAN
(4) pushbutton. The multimeter enters into the „REL“ mode.
The „REL“ symbol is displayed on the LCD. The value
„00.00“ (+1digit) is shown on the main display while the
capacitance measured at the time of pressing the pushbut-
tons is displayed on the sub-display and used as a refer-
ence value. This value is automatically deducted from the
values measured subsequently.
The REL function can be cleared
• by pressing and holding the PEAK pushbutton and then
pressing the AUTO/MAN key. This is acknowledged by
acoustic signals.
• by switching the multimeter off.
