Auto Range Digital Clamp Meter - True RMS 1000A AC/DC
4.3. AC Voltage Measurement
1. Insert the black test leads into the C
CO
OM
M and red into the V
V
Ω
Ω
H
Hz
z input terminals
respectively.
2. Set rotary dial at desired ‘V
V~
~’ position (default auto range).
3. Connect the test lead tips in parallel with the circuit to be measured. Be
careful not to touch any electrical conductors.
4. Read the measure result from the display.
4.4. Resistance Measurement
1. Insert the black and red test leads into the C
CO
OM
M and V
V
Ω
Ω
H
Hz
z input terminals
respectively.
2. Set rotary dial at desired
Ω
Ω
position.
3. The LCD will automatically select the
Ω
Ω
(default) symbol.
4. Connect the test lead tips in parallel with the resistance in the circuit being
measured.
5. Read the measure result from the display.
N
NO
OT

E::
• If the resistance being measured exceeds the maximum value of the range or
the input is not connected, an overrange indication ‘OL’ will be display.
• When checking in-circuit resistance, be sure the circuit under test has all
power removed and that all capacitors have been discharged fully.
4.5. Continuity Testing
1. Insert the black and red test leads into the C
CO
OM
M and V
V
Ω
Ω
H
Hz
z input terminals
respectively.
2. Set rotary dial at desired
Ω
Ω
position (default auto range).
3. Push ‘F
FU
UN
NC
C..’ button once to select (manual range).
4. Connect the test lead tips in parallel with the resistance in the circuit being
measured. If continuity exists (i.e. resistance less than 40
Ω
) built - in buzzer
will sound.
4.6. Diode Testing
1. Insert the black and red test leads into the C
CO
OM
M and V
V
Ω
Ω
H
Hz
z input terminals
respectively.
2. Set rotary dial at desired
Ω
Ω
position (default auto range).
3. Push ‘F
FU
UN
NC
C..’ button twice to select (manual range). The red leaded probe
should then be connected to the anode and the black leaded probe to the
cathode of the diode.
