key, select corresponding graduation 

no.; 

5.

  The LCD displays ‘0000’ , indicating waiting and then 

displays measurement result. And the refreshing rate 
is approximately once a second, and if the measured 
value exceeds the measurement range, the LCD 
displays ‘

6. Automatic 

compensation of cold junctions 

When calibrating meter with temperature cold 

junction compensation directly, press 

RJ-ON

key to 

start the automatic compensation function of cold 
junctions of this meter, and : 

Displayed temperature = the corresponding 

temperature of input thermoelectric force + room 
temperature 

7. Press

Section Seven Function Setting 

 

The following operation can change the automatic 

power off function of the meter: 
1. 

When the meter is in power-off state, press

power

key and the LCD displays fully , loose

power

key 

and pres

RANG

key, the meter enters into 

maintenance state and the LCD displays ‘AP –XX’ 

2.

 Press 

θ

key and the LCD displays symbol 

‘AP-OF’, the meter stops automatically power-off 
function ; The LCD displays symbol ‘AP-ON’, the 
meter restores automatically power-off function, and 
the meter exit from maintenance state if cutting off 
the power again.
