4. If a value is displayed, then the component is in working
order and the threshold voltage of the component is
displayed (approx 0.2 V in the case of Ge diodes, ap-
prox. 0.5 V in the case of Si diodes).
Measurement of capacitance
Discharge every capacitor before measurement!
Residual charge in the capacitor can destroy the
measuring instrument! Do not discharge the ca-
pacitor by short circuiting it; bridge the connec-
tions with a 100 KΩ resistor instead.
Never connect the measuring cables to a voltage
source. This will destroy the measuring instru-
ment.
For reasons of safety, measure to see if there is
any residual charge in the capacitor (use the DC V
range) before measuring capacitance.

1. Turn the rotary switch to
and select capacitance measurement using the
MODE button („nF" is displayed).
2. Insert the plug of the red measuring cable in the V/Ω
measuring socket and the black measuring cable in
the COM measuring socket.
3. Connect the capacitor to be measured to the measu-
ring tips. Electrolytic capacitors must be connected
with the correct polarity (+ to red, - to black). Since
the charging processes in capacitors require a little
time, the display may be delayed by up to 30 sec.
This is not a malfunction, but is system-related. Wait
until the display is stable before reading off the value.
A defective capacitor is shown by a display of zero or
around zero in all ranges if it is open circuit. Please note
that electrolytic capacitors can exhibit considerable va-
riance within their tolerance range.
