- Check test lead continuity. If the conductor in the test lead is damaged, the
leads should be discarded immediately.
- Remove test leads from circuit to be measured before turning the rotary
switch
to select another function.
- If the
01
is used near strong noise generating sources, the
display may become unstable and measurement errors may arise.
8.2 Voltage measurement
To avoid electrical shock, observe the maximum rated voltage
to earth ground !
The maximum rated voltage that should be applied between any of the following
terminals of the
01
and earth ground is 600 V.
- COM terminal
- Input terminal for V,
, and µA,
8.2.1 Voltage measurement
- Select the appropriate voltage type with the rotary switch
of the
MN 1
.
- Select manual range by pressing "RANGE" button if required.
-
Connect the black safety test lead to the COM-terminal
of the
MN 1
.
- Connect the red safety test lead to the input terminal for V,
and µA,
of
the
MN 1
.
- Connect the safety test leads to the circuit measurement points and read
the measured value on the digital display
of the
MN 1
.
see Figure 2:
Direct voltage measurement
see Figure 3:
Alternating voltage measurement
8.3 Direct current measurement
-
Select the range of direct current with the rotary switch
of the
MN 1
.
- Select manual range by pressing "RANGE" button if required.
-
Connect the black safety test lead to the COM-terminal
of the
MN 1
.
- Connect the red safety test lead to the input terminal for V, Ω, µA,
of the
MN 1
.
- Connect the safety test leads to the circuit measurement points and read
the measured value on the digital display
of the
MN 1
.
see Figure 4:
DC current measurement
8.4 Resistance Measurement
- Select the Ohm symbol Ω with the rotary switch
of the
MN 1
.
- Select manual range by pressing "RANGE" button if required.
-
Connect the black safety test lead to the COM-terminal
of the
MN 1
.
- Connect the red safety test lead to the input terminal for V,
and µA,
of
the
MN 1
.
- Connect the safety test leads to the circuit measurement points and read
the measured value on the digital display
of the
MN 1
.
see Figure 5:
Resistance measurement
8.5 Continuity Testing with Buzzer
- Turn the rotary switch
of the
MN 1
to select the appropriate
range identified by a buzzer and diode symbol
,
-
Connect the black safety test lead to the COM-terminal
of the
MN 1
.
- Connect the red safety test lead to the input terminal for V,
, µA,
of the
MN 1
.
- Connect the safety test leads to the circuit measurement points. If the circuit
resistance between the COM-terminal
and the input terminal for V, Ω
and µA,
falls below 20 Ω, then the built-in buzzer in the
MN 1
emits a continous tone.
- By means of the "RANGE" key, it is possible to change between the func-
tions continuity test and diode test.
see Figure 6:
Continuity Testing with buzzer
8.6 Diode Testing
- Turn the rotary switch
of the
MN 1
to select the appropriate
range identified by a buzzer and diode symbol
,
- Press the "RANGE" key to change to diode test function.
