5 Temperature Controller Detailed Operation
5.1 Switch on
1．Connect the power according to the power outlet with a protective ground connection.
2. Turn on the instrument by pressing the ON/OFF Button and the screen will light up. The
display shows the initialization sequence before the instrument is ready to use.
NOTE: Every time you turn on the instrument it beeps intermittently, the icon of visual alarm
and the word “end” will appear on the display, indicating that a heating cycle had been done
before. Press any button to silence the audible signal and the icon appears.
5.2 Setting of parameters
5.2.1 Time Settings
1．After confirming the temperature, the last value of the set time (timer) will start to flash. Set
the desired value (hh:mm) by pressing or keys. It’s possible for a quick movement
between the digits by using button.
2．Confirm the set value with another press of button.

52411Dryingoven_ver_1.0
www.coleparmer.com
NOTE: the value “00:00” indicates the operating mode is "continuous", that means once you
start operating cycle by the START / STOP button, the system will continues maintaining the
set temperature until it is stopped manually.
3．If you set the timer, such as one hour, the instrument will reach the set temperature and
maintain it for one hour.
5.2.2 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
keys.
2．The button works for a quick movement between the digits.
3．Confirm the set value with another press of button.
5.3 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).
3. Once timer runs out or after manual stop, the instrument beeps intermittently, the icon of
visual alarm and the word "end" appear on the display. Pressing any button will silence the
audible signal and the icon appears.
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.

5.4 Delay of heating cycle start
It’s possible to set a delay (hour and minutes) of heating cycle start.
Simultaneously Press and for few seconds until the time position shows “LK
0000”confirm the“0000” password pressing shortly 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) pressing or keys. It’s possible a quick
movement between the digits using 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 work
cycle but it doesn’t immediately heat: the word “end” and the set delay time 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 display.
5.5. Alarm / Faults
The oven has a built-in overtemperature 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 setpoint higher will also resume heating function.
If your oven alarm is sounding due to an elapsed timer, press the Any key to mute!

6.Calibration
6.1 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 the Pb value，Press to exit

While the oven arrives pre-calibrated from the factory, certain adjustments may be necessary
for optimal performance. Please note these adjustments will affect your oven settings! We
recommend writing down any factory settings prior to adjustment so they may be reset in the
event of undesirable operation.

7 Clean and maintenance
1. Make sure to take proper maintenance and cleaning of the instrument to guarantee its
conditions.
2. The inner chamber of the instrument is made of stainless steel, so it can be cleaned with any
detergent provided which is not aggressive and/or corrosive.
3. User should clean the inside and outside surfaces with a standard all-purpose cleaner
sprayed on a soft cloth.
4. Before proceeding with any cleaning or decontamination, the user must ensure that the
cleaning method will not damage the instrument.
IMPORTANT
If the instrument must be returned for service, it is necessary to provide for proper cleaning
and possible decontamination for pathogens.
The original package is recommended for the product if it needs to be sent it in for repairs. If
the original package is missing, it is necessary to provide another proper cover pack for
transportation.
Any damage caused from the incorrect shipping will not be covered by warranty.
7.1 Air Change (Forced air series only)
In forced air ovens, there is a knob on the top of the unit to open/close the air flap. Opening the
air flap on the back of chamber serves to adjust air change.
⚫If the air flap is open, fresh air comes in via aeration vent.
⚫If the air flap is completely open, the internal temperature accuracy and stability can be
negatively influenced.
