Resistance Measurement
•
Verify that the device under test is electrically dead.
External voltages would falsify the measured result!
•
Set the function selector switch (6) at „
Ω
“
.
•
Connect the device under test as shown.
Zero adjustment on the 660
Ω
measuring range
When measuring small resistance values on the 660
Ω
range,
you can eliminate the resistance of the leads and contact resis-
tance by means of the REL function.
•
Connect the test leads with the multimeter and join the free
ends.
•
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“ (+1 digit) is shown on the main display
while the resistance value measured at the time of pressing
the pushbuttons is indicated on the sub-display and used
as reference value.
•
This value is automatically deducted from the values mea-
sured 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.
