been done before. Press any button to silence.
8.4 Setting of Parameters
8.4.1 Time Settings
1. After confirming temperature, the last value of the set time (Timer) will start to flash.
Set the desired value (hh:mm) by pressing the or keys. It is possible to move
faster between the digits by using the button.
2. Confirm the set value with another press of the button.
NOTE: The value “00:00” indicates the operating mode is ‘continuous’, meaning once
you start the operating cycle by the START / STOP button, the system will continue to
maintain the set temperature until it is manually stopped.
3. If you set the timer, such as one hour, the instrument will reach the set temperature
and maintain it for one hour.
8.5 Temperature Setting
1. When the instrument is switched on, press the button one time and the set
temperature value will start to blink. Set the desired temperature value (in Celsius
degrees) by pressing the up and down arrow keys.
2．The button works for a quick movement between the digits.

User Manual
Version 1.0 15
8.6 Start / Stop Operation
1．After setting the operating parameters, press button for (about 4-5 seconds) to
start the heating cycle/cooling process with defined time in hh:mm or continue the
process for (00:00). When the word “END” disappears on the right corner of the screen,
the message “RUN” will appear in the left bottom and the system will display issues like
contemporary, timer, temperature measured inside the chamber.
2.At any time, you can always manually stop the cycle by pressing the button for (4-
5 seconds).

and the icon of the visual alarm and the word "end" appears on the display. Press any
button to silence.
NOTE: the acoustic signal will not end until it is stopped by the operator, but the heating
cycle will be terminated so the samples inside the instrument will remain exposed to the
internal temperature of the chamber.
8.7 Delay of Heating Cycle Start
1. It is possible to set a delay (hour and minutes) of the heating cycle start.
Simultaneously Press and for a few seconds until the time position shows “LK
0000” confirm the “0000” password pressing one time . On the top right part of
display the parameter “dy” (delay) appears close to value 00:00.
2. Set the desired delay value (hh:mm) by pressing or keys. For quick
movement between the digits use the button. Confirm the set value with another
press of button. The display comes back to the standby screen.
3. Pressing the button with long pressure (4-5 seconds) the instrument starts the

alternately blink on the top right part of display, counting the wait time until the real
starting of heating. Once the delayed time is passed the instrument starts to heat and
the regular timer appears on the display.

8.8 Alarm / Faults
The oven has a built-in over temperature protection circuit. If the oven’s temperature
overshoots, the controller will enter an alarm mode that disables all heating elements to
protect your samples.
When in alarm mode, a red alarm indicator will display on the screen. The oven will
automatically resume operation when the temperature has dropped back below the
overshoot threshold.
Setting the temperature set point higher will also resume the heating function. If your
oven alarm is sounding due to an elapsed timer, press the any key to mute.

IX. Calibration
9.1 Probe Calibration
Follow the instructions below to adjust the temperature readout.
These steps are only necessary in the event there is a discrepancy between the display
and measurements taken with an alternate device.
For Example:
A thermometer placed inside the oven with a different measurement than the controller.
Please Note:
Laser probe measurements will be inaccurate without compensating for emissivity.
Refer to your laser probe’s user manual.
1.Simultaneously press and for few seconds until the time position shows “LK
0000”
Press to set LK 0003
Press three times, you can see Pb, this is temperature offset on single point.
After set of the Pb value，press to exit.
