Making Measurements - VOLTCRAFT LCR-9063 Bedienungsanleitung

Important!
Avoid damage by never exceeding the max. input parameters.
4.3 Setting Up
When starting to measure, set the measuring device switch „0 - 1"
to „1" and, after finishing your measurements to „0" (this saves
wear on the battery). Measurement functions are color-coded: the
yellow range is for resistance measurement „R", the blue range
for capacitance measurement „C" and the violet range for induc-
tance measurement „L".
For switching between resistance measurement „R" and capaci-
tance „C" or inductance measurement „L", the slide switch must
be correctly set to „R - L/C".

5. Making Measurements

5.1 Capacitance Measurements (C)
Measure capacitance as follows:
1. Connect the measuring leads supplied to the measuring
device: the red measuring lead to the „+" socket (red) and
the black measuring lead to the „−" socket (black) and
switch the measuring device switch „0 - 1" to „1".
2. Always discharge capacitors before connecting them to the
measuring device.
Important!
Connection of capacitors can produce high-energy discharges.
Take care! Potentially lethal hazard! Do not touch the connec-
ting points of capacitors with voltages greater than 35 VDC or
8
25 VAC. Take precautions in rooms in which dust, combustible
gases, vapors or fluids are or may be present. ==> Danger of
explosion!
Do not measure capacitors which are built into circuits or circuit
components.
3. Set the measurement function switch to the measurement
range desired.
4. Set the slide switch „R - L/C" to „L/C".
5. Connect the discharged capacitor to be measured to the cro-
codile clips of the measuring leads.
With unipolar capacitors (poled) check that polarity is cor-
rect. Do not extend the measuring leads supplied using
other extension leads as the lead capacitance thus arising
cannot be compensated when automatically setting to zero.
This can result in measurement errors.
Note(s)!
a) With capacitors either unlabeled are having labels no longer
readable, start the measurement using the lowest possible
measurement range and continue to adjust the measure-
ment range switch until a sufficiently satisfactory display
(resolution) is obtained. Always remove the crocodile clips
from the measurement object before changing measure-
ment ranges.
b) It is normal if a continuously changing value is displayed in
the smallest measurement range (2 nF) before the measure-
ment is started. This is due to so-called stray capacitance in
the measuring leads, or the sensitive measurement input. At
very low capacitance values (e.g. 8.2 pF) the value displayed
(ahead of the measurement) must be deducted during the
measurement.
