or similar, etc. This might seriously influence the measuring result.
If resistance over 1 M
Ω
is measured, the display might need a few
seconds to stabilize.
During resistance measurement the three sub-displays below the main-
display are active. In the left sub-display the present reading is taken
1 second later, the middle display the reading is taken 2 seconds later
and in the right display the reading appears 3 seconds later.
5.5 Capacitance Measurement
Follow these steps to measure capacitance:
Set the rotary function switchto CAP (Lo) or CAP (Hi) and insert the
discharged capacitor into the appropriate socket observe the correct
polarity ("+" and "-"). If the are relatively low capacities as 100 pF or
smaller it better to use the special function "REL" (described under 4.4.3 c)
to set the display to "0000". In the other ranges (200 n or 20 u) wait a
few seconds until the off-set sets the display to "0000".
Attention!
When shorting capacitors (discharge), high-energy discharge may take
place. Caution life danger! Do not touch the terminals if there are capa-
citors with voltages over 35 VDC or 25 VAC. Use special caution in envi-
ronments or rooms with adverse environmental conditions where
flammable gases, vapour or dusts exist or may exist ==> explosion
hazard!
During capacitance measurement the three sub-displays below the
main-display are active. In the left sub-display the present reading is
taken 1 second later, the middle display the reading is taken 2 seconds
later and in the right display the reading appears 3 seconds later.
During capacitance measurement the voltage and the current terminals
and the transistor socket must not be connected.

During continuity check the measuring socket and the current sockets
must not be connected.
5.4 Resistance Measurement
Attention!
Make sure all objects, circuits and components under test are without
voltage! During continuity check the voltage measuring socket and the
current sockets must not be connected.
Proceed as follows:
1. Connect the black test-lead with the COM-socket (11) and the red
test-lead with the V/
Ω
socket (12).
2. Set the rotary function switch to resistance measurement Ohm.
Connect both test-lead tips to check the continuity of the test-leads.
3. Now connect the test-lead to the device you want to measure.
Hint
During resistance test, make sure that the contact between probes and
circuit is good. Make sure the test points are free of dirt, oil or solder flux
