Individual load and ambient condition might influent the temperature behaviour of the chamber� To compensate that influ-
ence there’s the option to neutralize by using the 3-point calibration and offset function� This function allows the tempera-
ture 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 value of temperature�
CAL 2: Temperature calibration and adjustment at medium value of temperature�
CAL 3: Temperature calibration and adjustment at high value of temperature�

Interface and output
The device can be connected to a PC and operated with the
laboratory software labworldsoft®through USB interface (5)�
Note: Please observe the system requirements as well as
the operating instruction and help section of 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�
Use the USB interface in conjunction with labworldsoft®for
operation in “Remote” mode and also to update the firm-
ware�
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�
Command syntax and format:
The following applies to the command set:
- Commands are generally sent from the computer (Master)
to the device (Slave)�
- The device sends only at the computer’s request� Even
fault indications cannot be sent spontaneously from the
device to the computer (automation system)�
- Commands are transmitted in capital letters�
- Commands and parameters including successive parame-
ters are separated by at least one space (Code: hex 0x20)�
- Each individual command (incl� parameters and data) and
each response are terminated with Blank CR LF (Code:
hex 0x20 hex 0x0d hex 0x20 hex 0x0A) and have a maxi-
mum length of 80 characters�
- The decimal separator in a number is a dot (Code: hex
0x2E)�
The above details correspond as far as possible to the recommendations of the NAMUR working party (NAMUR rec-
ommendations for the design of electrical plug connections for analogue and digital signal transmission on individual
items of laboratory control equipment, rev� 1�1)�
The NAMUR commands and the additional specific IKA®commands serve only as low level commands for communication
between the device and the PC� With a suitable terminal or communications programme these commands can be transmit-
ted directly to the device� The IKA®software package, Labworldsoft®, provides a convenient tool for controlling the device
and collecting data under MS Windows, and includes graphical entry features, for motor speed ramps for example�
Commands Function
