MEASURE TEMPERATURE

•
Turn the rotary knob to "TEMP".
•
Insert the K-type thermocouple into the input socket of the instrument, with the
positive end of the thermocouple (red) in the "
(black) in the "COM" socket.
•
Contact the probe of the thermocouple to the measured object and read the result
from the main display area on the screen.
•
Press the "°C/°F" button to switch between celsius and fahrenheit unit.
•
Note: When the thermocouple is not inserted it will display the temperature of the
environment.
•
The instrument is not suitable for measuring the temperature of a rapidly changing
environment.
•
The cold junction compensation of the thermocouple is set in the instrument,
and it takes a longer time to reach thermal balance with the environmental
measurements. When measuring without the thermocouple, the instrument
requires an adjustment period in the environment to obtain accurate readings.
•
The instrument uses K-type thermocouple probe.
•
When measuring temperature by thermocouple, the probe of the thermocouple
cannot contact the charged object, otherwise it may cause the instrument
damage, electric shock or personal injuries.
•
Caution: Do not fold the thermocouple wire into an acute angle. Repeatedly
bending the wire over a period of time may cause the wire to break.

MEASURE TRANSISTOR

•
Turn the rotary knob to "hFE".
•
Insert the multi-functional test socket in "10A" and "mA" sockets as
shown in the figure on the right.
•
Insert the transistor in the corresponding socket of the multi-functional
test socket.
•
Read the measurement results on the screen.
•
Use caution when using the multi-functional, pay attention to the
direction of the insertion; if it is reversed the test result will be wrong.
•
Do not use the multi-functional test socket in voltage and current measurement,
otherwise it may cause damage to the instrument, electric shock or personal
injuries.

AUTO POWER-OFF FUNCTION

•
If there's no operation for 15 minutes while the unit is turned on, the instrument will
enter 'Sleep' mode, meaning it will power off automatically to save battery power.
•
After entering sleep mode, the instrument will turn on if the rotary switch or any
buttons are pressed.
•
If the "FUNC." button is pressed to turn on the unit, it will cancel the auto power-off
function.
•
Note: When USB function is enabled, the instrument will not enter the sleep state.
