Type K Temperature Measurements
1.
Set the function switch to the
K
Temp
position.
2.
Insert the Temperature Probe into the negative
COM
and the
positive
TEMP
jacks, observing polarity.
3.
Touch the Temperature Probe tip to the device under test.
Continue to touch the part under test with the probe until the
reading stabilizes.
4.
Read the temperature on the display. The digital reading will
indicate the proper decimal point and value.
WARNING:
To avoid electric shock, be sure the thermocouple probe
has been removed before changing to another measurement function.
Note:
An open input or a temperature overrange the meter will display
“
OL
” and beep.
Note:
See the “Temperature Units” paragraph to select
°
F or
°
C
Note:
The temperature range of the supplied thermocouple probe is -20 to 250°C (-4 to
482°F)
Continuity Measurements
1.
Insert the black test lead into the negative
COM
terminal and the red test lead into the
Ω
positive terminal.
2.
Set the function switch to the

. The display icons will change when the
MODE
button is pressed.
4.
Touch the test probe tips across the circuit or component under test.
5.
If the resistance is < 40
Ω
, a tone will sound.
Diode Test
1.
Insert the black test lead banana plug into the negative
COM
jack and the red test
lead banana plug into the positive jack
2.
Turn the function switch to position. Use the
MODE
button to select the diode
function if necessary (diode symbol will appear on the LCD when in Diode test mode)
3.
Touch the test probe tips to the diode or semiconductor junction under test. Note the
meter reading
4.
Reverse the test lead polarity by reversing the red and black leads. Note this reading
5.
The diode or junction can be evaluated as follows:
If one reading displays a value (typically 0.400V to 0.900V) and the other
reading displays
OL
, the diode is good.
If both readings display
OL
the device is open.
If both readings are very small or ‘0’, the device is shorted.
