11. Temperature Measurement (UT161D, Picture 14)
1) Turn the function dial to the
position.
°C°F
2) Insert the K-type thermocouple into the adapter socket, and then insert the
adapter socket into the input terminals.
3) Bring the temperature sensing end of the thermocouple close to the object
surface under test.
4) Read the Celsius temperature value on the display after it gets steady.
5) Short press the
button to switch between °C and °F.
SELECT
Caution:
Only K-type thermocouple is applicable.
The LCD displays “OL” when the meter is turned on.
The measured temperature should be less than 230°C/446°F
(°F = °C × 1.8 + 32)
12. AC/DC Current Measurement (Picture 15)
1) Insert the red test lead into the
mA/μA
or
A
terminal, and black test lead into
the
COM
terminal.
2) Turn the function dial to the , , or position.
3) Short press the
button to switch to AC/DC current measurement if
required.
SELECT
4) Connect the test leads with the measured load or power supply in series.
5) Read the current value on the display (if the current is >10A, the red indicator
light will be on and the buzzer will sound an alarm).
6) When measuring AC current, short press the button to display the
frequency/duty ratio of the measured current.
Caution:
To prevent possible electric shock, fire, or personal injury, switch off the power
supply of the circuit, and then connect the meter with the circuit in series before
measuring the current.
If the range of the measured current is unknown, select the maximum range
and then accordingly reduce.
There are fuses inside
mA/μA
and
A
input terminals. Do not connect the test
leads with any circuit in parallel.
When the measured current is >5A, each measurement time should be ≤10s
and the rest interval should be ≥15 minutes.
When the temperature in the meter is ≥75°C after measurement of large current,
the yellow indicator light will be on, the buzzer will beep, and the LCD will display
“CUT”. When the temperature drops to <40°C, the yellow indicator light will be
off, and the measurement can be made.
