Calibration and adjustment (CALI):
CALI 0: Reset calibration
CALI 2: 2-point calibration
CALI 3: 3-points calibration
Example: 2-point calibration:
Dip the temperature sensor of the reference measuring
instrument into the bath fluid:
Select 2-point calibration in the menu� Press the "OK/
Pump" button (G) to start the 2-point calibration�
Set the first point temperature (e�g� 80 °C)� Confirm the set-
ting by pressing the "OK/Pump" button (G)�
Left area of the display appears the set value (80 °C) and
the right area of the display appears the actual temperature
value measured� The set LED (M) flashes briefly�
The device can be operated in "Remote" mode via the RS 232
interface (10) or the USB interface (11) connected to a PC and
with the laboratory software Labworldsoft
can also be updated with a PC via the USB or RS 232 interface�
Note: Please comply with the system requirements togeth-
er with the operating instructions and help section included
with the software�
USB interface:
The Universal Serial Bus (USB) is a serial bus for connecting
the device to the PC� Equipped with USB devices can be con-
nected to a PC during operation (hot plugging)� Connected
devices and their properties are automatically recognized�
USB device drivers:
First, download the latest driver for IKA devices with USB
interface from:
http://www.ika.com/ika/lws/download/usb-driver.zip.
Install the driver by running the setup file� Then connect the
IKA device through the USB data cable to the PC�
The data communication is via a virtual COM port� Configu-
ration, command syntax and commands of the virtual COM
ports are as described in RS 232 interface�
Note: the USB driver is unnecessary for Windows 10 system�
Don't install it for Windows 10 system!
The unit now starts and controls to the set value� When
the temperature has reached the set value and has become
constant, the "Set" LED (M) no longer flashes and the fol-
lowing display appears�
The temperature measured by the unit appears on the left
hand side�
Input the calibration value from the reference mesuring in-
strument (e�g� 80�2 °C) with the "Pump (+)" button (H) or
"Pump (-)" button (I)�
Confirm the value by pressing the "OK/Pump" button (G)�
Back to previous screen for input a new value by pressing
the "Temp" button (D)�
The first point calibration is finished now�
Calibration of the other points is performed in the same way�
