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 “    ” socket, and the negative end 

(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.

WARNING

• 

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.

WARNING

• 

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.
