I. Introduction:
y
This instrument is a four channel digital thermomete r for use with any K-type thermocouple as
temperature sensor. Temperature indication follows National Bureau of Standards and IEC584
temperature/voltage table for K-type thermocouples. It internal memory can keep up to 16,000
records per channel. (note1.) It uses RS232 interfa ce to perform bi-directional communication with
PC.

IV. Operation Ins tructions:
4.1 Power-Up & Turn ON/OFF backlight
I
The •
key turns the Thermometer ON or OFF and backlight ON & OFF.
Press it once to turn on the Thermometer.
Press it again for moment to turn ON or OFF backlight.
Press and hold this button 3 second to turn OFF the power.
4.2 Connection the Thermocouples
For measurement, plug the thermocouple into the input connectors.
4.3 Selecting the Temperature Scale
When the meter was powered on, the user may chang e it to Fahrenheit (°F) by pressing “
button and vice versa to Celsius.
4.4 Data-Hold Operation
The user may hold the present reading and k eep it on the display by pressing the “
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 op eration, the “MAX MIN”,“T1-T2” and “°C/°F” button are
disabled. (when you press “ °C/°F ”, “T1-T2” and “MAX MIN” button in HOLD mode, there will be
two continuous beeps)
4.5 T1-T2 Operation:
When this button is pushed, “
right hand side LCD display to indicate th at the tester is under T1
minus T2 mode. The temperature differenc e is shown on the right
hand side display as shown in Fig.
4.6 Record and Erase memory Operation:
When one presses the "REC" button, the m eter will start recording, and
pressing the "REC" button again will stop recording, If you want to clear the
memory, power off the meter, then press and hold “REC” button and then press
power button and hold at least 5 seconds, then LCD will show "CLR" “S URE 5”,
then release all buttons to clear the memory.
4.7 Clock Setup :
4.8 Recording Interval Setup :

3: press "REC" • or "°C/°F"
press “HOLD”(clock) to adjust next item. The adjusting order is
year•month•day•hour•minute, then press “HOLD” (clock) to finish
adjusting. If you want abort during a setup process, press power
button to cancel.

3: press "REC" • or "
press “MAXMIN " (INTV) to adjust next item, then press “MAXMIN”
(INTV) to finish. If you want abort durin g a setup process, press
4.9 MAX/MIN Operation:
When pressing the "MAX MIN" button the mete r will enter the MAX/MIN mode. Under th is mode the
maximum value, minimum value is kept in the memory simultaneously and up dated with every new
sample of data.
When the MAX symbol is display, the Maximum is shown on the display.
Press "MAX MIN" again, then the MIN symbol is on the display and also the minimum reading.
Press "MAX MIN" again, MAX, and MIN will blink together. This means that all these data is
updated in the memory and the reading is the present temperature.
One may press "MAX MIN" to circulate the display mode among these options.
When the meter is under "MAX MIN" operation and “ °C/°F ” button are disabled.(when you press
“ °C/°F ” button in "MAX MIN" mode, there will be two continuous beep)
To exit the MAX/MIN mode, one may press and hold "MAX MIN" for two seconds.
4.10 Auto Power Off:
By default, when the meter is powered on, it is und er auto power off mode. The meter will power
itself off after 30 minutes if no key operation and no RS232 c ommunication combination at power on
can disable auto power off.
One may press and hold “
successive beeps to indicate that auto power off is disabled and the will not show up.
4.11 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.
4.12 Calibration Point:
