Range Accuracy
K-Type -200°C ~ 1370°C ±(0.1% reading + 0.7°C)
J-Type -200°C ~ 760°C ±(0.1% reading + 0.7°C)
K-Type -328°F ~ 2498°F ±(0.1% reading + 1.4°F)
J-Type -328°F ~ 1400°F ±(0.1% reading + 1.4°F)
Temperature Coefficient:
For ambient temperatures from 0°C ~ 18°C and
28°C ~ 50°C, for each °C ambient below 18°C or
above 28°C add the following tolerance into the
accuracy spec.
0.01% of reading + 0.03°C
( 0.01% of reading + 0.06°F )

IV. Operation Instructions:
4.1 Power-Up
Press the •
Ikey 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
hold 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 Timer Operation:
One may start the timer by press the “ TIMER ”
button. The counting can be stopped or continued by
pressing it again.

7
When the counting exceed 59min 59sec, the time
scale will be changed to hours and minutes and the
“ H” symbol will appear on the display.
The counting can be reset by press and hold
“ TIMER ” button for 2 sec.
4.7 Relative Operation:
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.
4.8 MAX/MIN/AVG Operation:
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 int
the memory and the reading is the present
temperature.
One may press to circulate the display mode
among these options.
When the meter is under operation, “•REL”

8
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
after30 minutes if no key operation and 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.
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.
TX RX GND

For example:
T1••••••-199.9••C••••

10
(0x13) represent T1,- 199.9°C, The total byte number
should be 7+1+7+1+5+chr(13)=22Bytes
Command B:
Return the counting of timer.
•Command S:

mode is not entered, the related characters will be
left as space.
For example:
when the meter is under MAX display, the meter will
return: •••••MAX••••
•Command T:
