1. Set the Rotary Dial to
position.
2. Connect the red test
lead to the VΩ ter-
minal and the black
test lead to the COM
terminal.
3. Connect the red test
lead to the positive
(+) side and black
test leads to the
negative (-) side
of the circuit under
test. The reading is displayed. A reversed con-
nection is indicated as a negative value.
Resistance/Continuity/Capacitance
Measurements
DANGER
To reduce the risk of electric shock
for Resistance, Continuity, and
Capacitance measurements, never use the meter
on an energized circuit. Make sure a capacitor is
fully discharged before touching or attempting
to make a measurement.
Do not use with the Battery Cover removed.
Resistance
1. Set the Rotary Dial to
position.
2. Connect the red test
lead to the VΩ terminal
and the black test lead
to the COM terminal.
Confirm “OL” is indi-
cated on the display,
and then short-circuit
the tips of test leads
to make the indication
zero.
3. Connect the test leads
to both ends of the
resistor under test.
4. The reading is displayed.
CAUTION
After shorting the test leads, the
displayed value may not be zero
due to the resistance of test leads themselves.
Continuity
1. Set the Rotary Dial to posi-
tion.
2. Connect the red test lead to the
VΩ terminal and the black test
lead to the COM terminal.
Confirm “OL” is indicated on
the display, and then short-
circuit the tips of test leads to
make the indication zero. A
buzzer will sound.
3. Connect the test leads to both
ends of the conductor under
test. If the resistance under
test is 35 ±10Ω or 25Ω or less,
the buzzer will sound.
Capacitance
1. Set the Rotary Dial to
position.
2. Connect the red test lead to the VΩ terminal and
the black test lead to the COM terminal.
3. Discharge capacitor.
4. Connect the test leads to both ends of the capaci-
tor under test.
5. The reading is displayed.
DC Current (Cat. No. 2236-20 only)
DANGER
To avoid electrical shock:
Never make measurement on a
circuit in which voltage over AC600V exists.
Do not use with the Battery Cover removed.
1. Set the Rotary Dial to
Flame
sensor
probe
Control
Module
position. DC mark is
displayed.
2. Connect the red test
lead to the VΩ terminal
and the black test lead
to the COM terminal.
Contact the red test
lead to the flame sen-
sor probe and the black
test lead to the control
module.
3. Turn on the heating
unit. The reading is
displayed.
Temperature (Cat. No. 2236-20 only)
WARNING
Never connect
the Tempera-
ture Probe to an energized
circuit.
1. Set the Rotary Dial to
posi-
tion.
2. Connect the K-type Tem-
perature Probe to the input
terminal. The positive (+) side
of Probe should be connected
to VΩ.
3. Place the probe sensor in the
desired location.
4. The reading is displayed.
CAUTION
When the Rotary Dial is set to ,
the room temperature should be
displayed. If anything else is displayed, some-
thing may be wrong with the meter. Stop using
the meter immediately.
