Intended use
Use
The IKA Oven 125 basic - dry is a drying oven for a wide range of
heating, drying and heating applications.
The device must only be used for heating up non-explosive sub-
Useful information
Calibration and adjustment
This menu shows how offset values can be entered after the re-
spective temperatures are approached and cross-checked with an
external measuring device (calibrated).
Individual load and ambient conditions might influence the tem-
perature behaviour of the chamber. This influence can be neutral-
ised by using the 3-point calibration and offset function. This func-
tion allows the temperature to be calibrated and adjusted at three
different temperature values.
Use a calibrated reference measuring device in case of adjustment.
The operation can be done at a single, or up to three temperature
levels:
CAL 1: Temperature calibration and adjustment at low tempera-
ture value.
CAL 2: Temperature calibration and adjustment at medium tem-
perature value.
CAL 3: Temperature calibration and adjustment at high tempera-
ture value.
stances and objects. Do not process substances or objects that
might cause explosive vapour.
Area of use (indoor use only)
- Laboratories - Schools
- Pharmacies - Universities - Industry
Your safety cannot be guaranteed:
• If the device is operated with accessories that are not supplied
or recommended by IKA.
• If the device is operated improperly or in contravention of the
IKA specifications.
• If the device or the printed circuit board are modified by third
parties.
General
Door open detection
CAUTION Hot air may stream out when the
door is opened. The inner chamber
may also stay at high temperatures
for some time.
NOTICE The heating function and oven fan
may be in operation even if the
door is open.
When the door is open the icon will be displayed and the
chamber light will be switched on.
Graph
The scaling of the temperature axis (Y-axis) is automatically deter-
mined, depending on the target temperature and the actual inter-
nal and external temperature.
The time axis (X-axis) is permanently scaled to 1 hour.
Data management
Data logging function is automatically active when USB storage
device is plugged in and tempering function is active.
The sampling time is fixed at 10 seconds. The data will be saved in
a read only CSV file (.csv) name “IKAyymmddhhmm” on the USB
storage device, where “yymmddhhmm” is the date and time of the
heating function is turned on.
Example: “IKA1812312359.csv”, data log on 2018 December 31 at
11:59pm. T he data that are being logged will be in sequence as follows.
1. Date (YY/MM/DD)
2. Time (HH:MM:SS)
3. Limit Temperature (°C / °F)
4. Set Temperature (°C / °F)
5. Control Temperature (Reference sensor)

Temperature monitoring
The temperature monitoring function is a constantly active function
whenever the heating operation of the device is turned “ON”. The
main purpose of this function is to notify the user in the case of
abnormal temperature behaviour such as overshoot and undershoot.
The hysteresis level is adjustable from 1.0 K to 20.0 K and the
factory default value would be 10.0 K. Furthermore, there will be
an additional option to turn “OFF” the heating operation when
temperature is behaving abnormally.
Case 1: Temperature overshoot
When the temperature overshoots the stable set temperature and
exceeds the predefined hysteresis limit, the icon will be shown
on the main screen of the device.
If the user has selected the option to turn “OFF” heating operation,
heating operation will be automatically turned “OFF” when the
temperature exceeds the predefined hysteresis limit or else heating
operation will continue.
Case 2: Temperature undershoot
When the temperature falls below from stable set temperature and
passes the predefined hysteresis limit, the icon will be shown on
the main screen of the device.
If the user has selected the option to turn “OFF” heating operation,
heating operation will be automatically turned “OFF” when the
temperature falls below the predefined hysteresis limit or else
heating operation will continue.
Case 3: Temperature exceeds hysteresis limit and recovers
If the user did not select the option to turn “OFF” heating operation,
whenever the temperature overshoots or undershoots the stable
set temperature and passes the predefined hysteresis limit, the
icon will be shown on the main screen of the device.
When the temperature recovers to the stable set temperature, the
icon will still remain on the main screen of the device until the
user stops the heating operation or changes the set temperature.
Case 4: Door Open during heating operation “ON”
Whenever door open is detected while entire heating operation
is turned “ON”, the temperature monitor function will be
automatically suspended.
The temperature monitoring function will automatically resume
when the temperature has reached the set temperature and is
stable.
The icon will only be remove when the tempering operation
is stopped and when the set temperature changes while the
tempering operation is operating.
Generally the graph below explains the temperature monitoring
function in 4 cases.

Internal / external temperature sensor
The temperature is regulated according to the internal/external
temperature sensor.
Temperature monitoring
You can monitor the temperature behaviour. If the temperature
behaviour exceeds the defined hysteresis value, the symbol ap-
pears at the actual temperature.
Hysteresis
This enables the temperature control function of the device to
switch off when the actual temperature exceeds the specified hys-
teresis value. It also defines the permitted tolerance of temperature
variation.
Calibration and adjustment
This makes it possible to adapt the temperature display, to get
more precise temperature regulation.
• Internal temperature sensor / external temperature sensor:
The external/internal temperature sensor is adapted here us-
ing the 3-point calibration.
Actual temperature note
Gives a notification when the actual temperature is in the range
of ± 1.0 K of the target temperature and the symbol is shown
next to the target temperature.
Timer (Zeitschaltuhr)
Counter (service hour counter)
The counter function counts as soon as the heating function is
active. The maximum value is 9:23:59 (Days: Hours: Minutes).
Timer (adjustable operating duration)
The timer function starts as soon as the temperature control func-
tion is active. The remaining time is shown on the display. When
the specified time has elapsed the heating function is switched
off. The maximum value is 9:23:59 (Days: Hours: Minutes).
Control
Counter and timer setting options:
• Time: The counter and timer are controlled depending on
the time. The counter and timer start running immediately,
whether the target temperature has been reached or not.
• Temperature: The counter and timer work according to tem-
perature. They only start running when the target tempera-
ture has been reached.
Menüdetails
Temperature control
Control mode
The option of changing between two PID modes, and the tem-
perature reference sensor.
Exact PID control
For use with temperature-
sensitive materials that must
be handled with care.
Advantages:
• Precise temperature control
• Minimum deviation above/below the target temperature
Disadvantage:
• Longer heating up time
Fast PID control
For use when a fast heating
up time is needed and there
should then be precise tem-
perature control.
Advantage:
• Short heating up time
Disadvantage:
• There will be a certain level of deviation above and below the
target temperature.

15
NOTICE
After the temperature method
is selected, the control hysteresis
can be controlled (± x.x K) by
turning and pressing the rotary/
push knob (E) once again.
3. Gradient-controlled (Ramp)
This enables even heating up with a defined gradient The
segment is closed after the target temperature has been
reached.
The gradient in K/min comes from the quotient of the
temperature difference and the time “Time hh:mm” specified in
the current segment.
The temperature difference is calculated from the target value
temperatures of the current and preceding segment.
NOTICE
The ramp function can only be
selected from the 2nd segment.
• “Time hh:mm” column (see “Control Mode”)
• “Fan” column ( Fan speed in % for this segment)
•“Ventilation flap” column (position of the ventilation flap for
this segment)
Delete

Programs
Under programs, 5 user-defined temperature-time profiles can be
created. A program can consist of up to 5 segments. Once a pro-
gram has been selected, the following options are available:
Start
Starts the program when loop mode is requested.
•Infinite loop: Upon completion of the last segment, the pro-
gram continues with the first segment until the user ends the
program by stopping a device function.
•Loop Count: Indicates the total number of loop cycles until pro-
gram end.
NOTICE
At the end of the program all device
functions are switched off.
Edit
The program parameters are edited/changed in a matrix of lines
(segments) and columns (functions):
• “Seg No.” column (Segment Number)
• “Temp” column (specifies the desired target temperature)
• “Control .Mode” column
The temperature-time profiles can be created using 3 different
methods. Choose the method you want by turning then
confirming (pressing) the rotary/push knob (E) .
1. Time-controlled (Time)
In “Control Mode Time” the target values and settings
of the segment are valid for the duration indicated in the
column “Time hh:mm”. The end of the segment is reached
when the time specified in the column “Time hh:mm” has
elapsed – regardless of whether the target temperature
specified in the column “Temp” has been reached or not.
2. Time-controlled (± x.x K)
a) Value in the column “Time hh:mm” =0
The segment is ended when the target temperature specified
in the “Temp” column is reached within the control hysteresis
(tolerance) specified in the column “Control Mode (± x.x K)”.
b) Value in the column “Time hh:mm” <>0
As a). Also, the target temperature that has been reached is
maintained for the time specified in the column “Time hh:mm”.
