IV. Operation Instructions:

4.1 Power-Up

Press the
When the user powers on, the LCD will show how much memory
space is available to use.

For example: It indicates that there are 16,000 records memory space available.

4.2 Connection the Thermocouples

For measurement, plug the thermocouple into the input connectors.

4.3 Selecting the Temperature Scale

When the meter is first powered 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. Next time
you power on, the scale setting will be the same as which when you powerd off last time.

4.4 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 “TIME”, "MAX MIN" and “ °C/°F ” button are
disabled. (when you press "TIME” ,“ °C/°F ” and "max min" button in HOLD mode, there will be
two continuous beeps)
To exit the MAX/MIN mode, one may press and hold "MAX MIN" button for two seconds.

4.5 DataLogger:

When one presses the "REC" button, the meter 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 2
seconds, then release all buttons ,then LCD will show "CLR" to
clear the memory.

4.6 Clock Setup:

power button

to turn the thermometer ON or OFF.

1: press and hold “MAX MIN” button and then power on the meter:

2: press “TIME”(clock):

3: press "REC" ▲ or "°C/°F" ▼ to increase or decrease number,

press “TIME”(clock) to adjust next item. The adjusting order is
year→month→ day→hour→ minute, then press “TIME” (clock) to

finish adjusting. If you want abort during a setup process, press
power button to cancel.

HH306A

4.7 Recording Interval Setup :

1: press and hold “MAX MIN” button and then power on the meter:

2: press “HOLD"(INTV)

3: press "REC" ▲ or "°C/°F" ▼ to increase or decrease number,

press “HOLD" (INTV) to adjust next item, then press “HOLD” (INTV)
to finish. If you want abort during a setup process, press power

4.8 Time Operation:

When pressing the “TIME” button, the LCD will display time , it will show year on top of the LCD,
show month and day on the left bottom of the LCD, show hour and minute on the right bottom of
the LCD. Press "TIME" button or any other button will exit this mode. This operation will not interrupt
the recording and "MAX MIN" operation.

4.9 MAX/MIN Operation:

When pressing the "MAX MIN" button the meter will enter the MAX/MIN mode. Under this mode the
maximum value, minimum value is kept in the memory simultaneously and updated 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 under auto power off mode. The meter will power
itself off after 30 minutes if no key operation and no RS232 communication combination at power on
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 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:

input Adjust VR tolerance

0 °C VR1 ± 0.1 °C

190 °C VR2 ± 0.1 °C
1000 °C VR3 ± 1 °C
1900 °F VR4 ± 1 °F

button to cancel.

P. S

Normally, performing offset Calibration with thermal
stabled ice water through VR1 will give a very good
calibration result.
