4. Taking Measurements
•
When taking measurements, make sure there is a good connection be-
tween the measured resistor and the probes. Contamination on the probes
or on the connectors of the resistor may cause erroneous results.
•
If the measuring range is exceeded or nothing is connected to the probes,
the overflow symbol “OL” is displayed.
4.3 Capacitance Measurement
Please Notice!
•
Take extra care to avoid touching uninsulated connectors (electric shock!
Danger of injury). In every case, discharge larger capacitors before taking
measurements. Residual voltage in capacitors may destroy the unit. Do
not discharge capacitors by short-circuiting them, but bridge them with a
100 k
Ω
resistor.
•
Never connect the probes to a power source, this may destroy the unit.
Measuring Procedure for measuring Capacitors
1. Press the “FUNC.” button to turn the unit on. Press the function but-
ton repeatedly until the capacitance symbol and the measuring
unit “nF” are displayed.
2. Connect the capacitor to be measured to the probes and read the
measured value from the display. The measuring range is set auto-
matically (nF or µF).
Please Notice:
•
When electrolytic capacitors are measured, correct polarity must be ob-
served. To make this possible, there are polarity symbols “-“and “+” on the
probes.
•
With electrolytic capacitors of larger capacitance it may take up to 30 sec-
onds until the final value is displayed steadily (measured value builds up in
two steps).
