8.3 DC CURRENT
1. Connect the black test lead to COM probe socket and the red to the V
Ω
mA probe
socket for a maximum 200mA current, for a maximum 10A current, move the red lead
to the 10A probe socket.
2. Set the measurement function range switch to the desired range position.
8.4 RESISTANCE (
Ω
)
1. Connect the black test lead to COM
probe socket and the red to V
Ω
mA
probe socket.
2.
Set the measurement function range switch to the desired
Ω
range position.
Note:
A) When measuring resistance above 1M
Ω
, the reading may take a few seconds to
become stable.
B) When the input is not connected, i.e. at open circuit, the figure ‘1’ will be displayed.
C) When checking in-circuit resistance, be sure the circuit under test is switched off
and that all capacitors have been discharged fully.
E) When the measurement is uknown always set the measurement function range
switch to the highest position.
8.5 TEMPERATURE (41818 ONLY)
1. Connect the black temperature probe lead to COM probe socket and the red to V
Ω
mA
probe socket.
2. Set the measurement function range switch to the desired °C position.
WARNING: DO NOT USE ON VOLTAGES ABOVE 600V.
8.1 DC VOLTAGE
1. Connect the black test lead to COM probe socket and the red to V
Ω
mA probe socket.
2. Set the measurement function range switch to the desired range position.
Note:
A) When the measurement is unknown always, set the highest position.
8.2 AC VOLTAGE
1. Connect the black test lead to COM
probe socket and the red to V
Ω
mA
probe socket.
2. Set the
measurement function range switch to the desired V~ position.
Note:
A) When the measurement is unknown always, set the highest position.
