IV. Operation Instructions :  
4.1 Power-Up  
I
Press the key to turn the thermometer On or OFF.  
4.2 Connection the Thermocouples  
For measurement, plug the thermocouple into the input  
connectors.  
4.3 Selecting the Temperature Scale  
When the meter was first power on, the default scale setting is  
set at Celsius (°C) scale. The user may change it to Fahrenheit  
(°F) by pressing “ °C/°F ” button and vice versa to Celsius.  
4.4 Selecting the Thermocouple Type  
By default, when the meter is powered on, it is K-Type, One may  
press and hold °C/°F” button and then power on the meter, then  
it will change to J-Type.  
4.5 Data-Hold Operation  
The user may hold the present reading and keep it on the display  
by pressing the HOLD” button. When the held data is no longer  
needed, one may release the data-hold operation by pressing  
HOLD” button again.  
When the meter is under Data Hold operation, the REL”,  
and “ °C/°F ” button are disabled.  
4.6 T1,T2,T1-T2 Display Control:  
One may select T1,T2 or T1-T2 to show on the main display by  
pressing  
button. When T1 or T2 is select to show on the  
main display, the other temperature will be shown on the second  
display. When one select T1-T2 to show on the main display,  
T1 and T2 will be shown on the second display alternately.  
4.7 Relative Operation for Main Display:  
When one press the REL” button, the meter will memorize  
the present reading and the difference between the new  
reading and the memorized data will be shown on the display.  
Press the REL” button again to exit the Relative operation.  
 
Type K J Thermometer  
4.8 MAX/MIN/AVG Operation for Main Display:  
When one press the button the meter will enter  
the MAX/MIN mode. Under this mode the maximum value,  
minimum value and average value of latest 4 data is kept in the  
memory simultaneously and updated with every new data.  
When the MAX symbol is display, the Maximum is shown on the  
display.  
Press  
again, then the NIN symbol is on the display and  
also the minimum reading.  
Press  
again, the AVG symbol is on the display and also  
the average reading.  
Press  
again, MAX, MIN and AVG will blink together. This  
means that all these data is updated in the memory and the  
reading is the present temperature.  
One may press  
these options.  
to circulate the display mode among  
When the meter is under  
operation, “REL” and  
°C/°F are disabled.  
To exit the MAX/MIN mode, one may press and hold  
for two seconds.  
4.9 Auto Power Off:  
By default, when the meter is powered on, it is under auto power  
off mode. The meter will power itself off after 30 minutes if no key  
operation or RS232 communication.Key combination at power on  
or RS232 communication can disable auto power off.  
One may press and hold HOLD” button and then power on the  
meter and there will be two successive beeps to indicate that auto  
power off is disabled.  
4.10 Low Battery Condition  
When the battery voltage is under proper operation requirement,  
the  
symbol will show on the LCD and the battery need to  
be replaced with new one.  
 
Type K J Thermometer  
4.11 Digital Output:  
The Digital Output is a 9600bps N 81 serial interface.  
The RX is a 5V normal high input port.  
The TX is a 5V normal high output port.  
The command of Digital Output is list below.
