Temperature Measurement
To measure temperature, connect the meter as follows:
•
Set the rotary switch to ºC to measure degree celsius temperature.
•
Insert the multi-purpose socket into the corresponding Hz and COM terminal.
•
Insert the temperature probe to the corresponding input terminal of the multi-
purpose socket. Take care to ensure that proper polarity is observed when
connecting to this socket.
•
Place the temperature probe to the object being measured. The measured value
shows on the display after few seconds.
•
The included point contact temperature probe can only be used under 230ºC.
•
For any measurement higher than that, the rod type temperature probe must be
used instead.
•
When temperature measurement has been completed, disconnect the connection
between the temperature probe, multi-purpose socket and the circuit under test
and remove the multi-purpose socket from the input terminal.
Note
The testing environment must between 18ºC to 28ºC to ensure accuracy especially
when measuring low temperature. Different reading may be obtained when testing
room environment under short or open circuit situation, then short-circuited reading
shall be considered as the correct reading.
Turning on the Display Backlight
Warning:
In order to avoid the hazard arising from mistaken readings in low light
situations, please use display backlight function.
•
Press LIGHT button to turn the display backlight on.
•
Press LIGHT button again to turn the display backlight off.
•
When using the AC power, the display backlight always stays on.
Measuring Transistor
To measure transistor, connect the meter as follows:
•
Insert the multi-purpose socket into the μAmA and Hz input terminal.
•
Set the rotary switch to hFE.
•
Insert the NPN or PNP type transistor to be tested into the corresponding input
terminals of the multipurpose socket.
•
The measured nearest transistor value shows on the display.
•
When transistor measurement has been completed, remove the tested transistor
from the multi-purpose socket and remove the multi-purpose socket from the input
terminal.
