Temperature Measurement
：
1. Turn on the power switch and set the rotary switch to the position
℃
.
2. The ‘LCD’ display will show the approx. current environment temperature.
3. Press the FUNC. key to select the
℃
or
℉
measurement modes.
4. When measuring the temperature with thermocouple, ‘K’ type probe for this meter can be used. Insert the black plug to
the COM jack and the red one to the
℃
jack, touch the end of the temperature sensor to the area or surface of the object
for measurement.
5. You can get reading from LCD.
DC/AC
μA Measurement ：
The measurement is seen in Figure 3-8
, the measurement range of current is of AC or DC 0.01μA
～
22
00μA, and the
measurement methods are as follows:
1. Turn on the power switch and set the rotary switch to the position .
2. Insert the red testing line into the
mA/μA
input end and the black testing line into the COM input end.
3. Press the FUNC. key to select the
DcμA or AcμA
measurement modes.
4. Turn off the power of the measured circuit, connect the red and black probes to the measured circuit in serial way and
then turn on the power of the measured circuit.
5. Read the measured value from the display screen. If it displays as positive during the DC measurement, it means the
current is flowing into the meter from the red testing line, while it displaying as negative, it means the current is
flowing into the meter from the black testing line. If it displays as OL, it means current exceeding range.
6. During measurement of DC
μA or AcμA ，
it is possible to select range manually by pressing the RANGE key.
Notes: In this mode the Meter may display a initial reading between 1 and 5 counts when no signal input, but that will not affect the
accuracy of measurement. Using REL to offset this reading may produce a much larger constant error in later measurements.
