MEASURING RESISTANCE
••
Warning
••
To avoid electrical shock or damage to the meter when measuring resistance,
turn off all power to the circuit and discharge all high-voltage capacitors.
(1) Turn the rotary switch to the
position and press the
FUNC
button until
Ω
,
k
Ω
or
M
Ω
appears on the right side of the LCD.
(2) Plug the black test lead into the front-panel
COM
jack and the red test lead
into the
jack.
(3) Measure the resistance by touching the test leads to the desired test points
of the circuit or to the terminals of a component, as shown below.
(4) Read the measured resistance on the display. If you are working in Manual
Ranging mode and the readout is
.OL
, the resistance value is beyond the
currently selected range. If that is the case, use the
FUNC
button to select
the next-widest position.
MEASURING TEMPERATURE
The DMM includes a “K” type bead thermocouple probe for measuring surface
temperatures. To use it,
(1) Insert the
+V
plug of the plug adapter to which the thermocouple is
attached into the
jack.
(2) Insert the
COM
plug of the plug adapter into the
COM
jack of the DMM.
(3) Turn the rotary switch to the
TEMP
position.
(4) Press the
FUNC
button until your preferred temperature measurement
unit—
ºF
or
ºC
—appears on the right side of the LCD.
(5) Attach the bead probe to the surface whose temperature you wish to
measure. The reading will be shown on the LCD.
