Taking Measurements
Procedure
1. Connect the red measuring probe to the “V/
Ω / /BATT9V“
input (5) and the black probe to the COM input (6).
2. Set the rotary function switch (4) to the position “ Ω “ (20M, 2M,
200k, 20k, 2k, 200).
3. Now connect the measuring probes to the resistor to be
measured.
4. According to the setting of the rotary function switch, the
display shows the value in
Ω
, k
Ω
or M
Ω
. When shifting
through the ranges, the decimal point shifts in the display
corresponding to the corresponding range.
Hints
ƒ
When measuring small resistances (200 Ω range) the
accuracy of the measurement can be adversely influenced by
the inherent resistance of the measurement cables.
To determine the inherent resistance of the cables is shorten-
ing them out by connecting the probes. The displayed resis-
tance value is the inherent resistance of the cables, which
must be deducted from the measured result to achieve a
correct final result.
ƒ
Ensure good contact between the probes and the testes
object during the resistance test. Dirt or other forms of con-
tamination on the test probes or leads of the resistor may
result in incorrect readings.
ƒ If the measuring range is exceeded the display will show the
overload symbol “1“.
Diode Test Function
With this function you can test diodes and other semiconductors
for continuity and blocking function and determine their function-
ality.
