KMD 02
Digital multimeter
3. Determine whether the transistor
to be tested is NPN pr PNP type
and locate the Emitter, Base and
Collector leads.
4. Insert leads of the transistor into
proper holes of the special multi-
function socket.
5. The meter will show the approx.
hFE value at test condition of base
current 10μA and Vce 2.8V.

Frequency measurement

Warning
Do not measure Frequency on
high voltage (>250V) to avoid
electrical shock hazard and/or
damage to the instrument.
Frequency is the number of cycles a
voltage or current signal completes
each second.
To measure frequency:
1. Set rotary switch to 20kHz range.
2. Connect the black and red test
leads to the COM and Hz terminals
respectively.
3. Connect the test leads to the
circuit being measured.
4. Read the displayed value.

Temperature measurement

Warning
To avoid electrical shock and/
or damage to the instrument,
do not apply more than 250Vdc
or 250Vac rms between the ºC
terminal and the COM terminal.
To avoid electrical shock, do not
use this instrument when voltages
at the measurement surface
exceed 60v dc or 24v rms. Ac.
To avoid damage or burns. Do not
make temperature measurements
in microwave ovens.
To measure temperature:
1. Set the rotary switch to TEMP
range and the LCD will show the
current environment temperature.
2. Connect the"comp" plug and
"+"plug of the special multi-
function socket to the COM and
Temp terminals.
3. lnsert 'K' type thermocouples
into the special multi-function
socket, taking care to observe the
correct polarity.
4. Touch the object with the
thermocouple probe for
measurement.
5. Read the stable reading from LCD.
