Current Measurement - Prokit's Industries Pro's Kit MT-1280D User Manual

reach 300˚C.
3.2.9 hFE Measurement:
To avoid any electric shock and/or damage to the meter, do
not attempt the hFE test if the voltage is over DC & AC 36V.

Turn the switch to the position hFE.

Check the transistor is NPN or PNP type first, then plug in the
emitter, base and collector separately to the correct hole, the
approximate value will be showed on LCD.

3.2.10 Current Measurement:

To avoid any electric shock and/or damage to the meter, do not
attempt the current measurement if the voltage is over 250V.
In the current measurement position, when the LCD shows
"FUSE" and the buzzer alarms, the fuse is burnt. Please replace
the fuse. In the current measurement, please make sure to
apply the correct input socket, position, and measuring range.
When one of the test leads is connecting to a live circuit, please
do not connect another one to any circuit. When the
measuring current is over 5A, please do not measure over 10
seconds.

Turn the switch to the proper current position.
Note:
When the LCD shows the symbol of "LEAd" for a short time as a

reminder to plug in the test leads correctly.

Connect the black test lead to COM input socket. Connect the red
test lead to mA input socket when the measured current is less than
600mA; to 20A input socket when the measured current is
600mA~20A.

Disconnect the measured circuit, connect the black test lead to
lower voltage and the red test lead to higher voltage.

Connect the power to the circuit and will get the reading on LCD
display. If the display shows "OL", which means the input power is
over the selected range. Turn the switch to a higher measuring
range.
