Initial operation 6. Use the arrow keys to switch to the low temperature limit <tLo> then repeat steps 3 and 4 for the lower temperature limit. The temperature warning limits are set. After a short time, the display changes to standby mode or temperature control mode depending on the status.
Operation Operation Switch on the unit This section describes how to switch on the device. The unit is connected and ready for operation. 1. Switch the unit on at the mains switch. All display elements light up briefly, the software boots and starts the device.
[OK] key. Observe the following for heating circulators: For temperature control applications near or below the ambient temperature: Use a cooling coil or JULABO immersion cooler. Activate autostart function The autostart function makes it possible to start a temperature control application directly using the mains switch or via an intermediate timer.
Operation 4. Use the arrow keys to select <On> and confirm with [OK]. The display flashes briefly. The autostart function is activated. The next time the device is switched on, the temperature control application will immediately start with the preset values.
1. Connect the circulator (USB port type B) to the computer with a standard USB cable. 2. Download the suitable USB driver from the download area of the website www.julabo.com. Depending on the operating system used by the connected computer, it may be necessary to install the USB driver.
Operation 4. Switch the circulator on. 5. Press the [MENU] key. 6. Use the arrow keys to select the menu option <IntE> and confirm with [OK]. 7. Use the arrow keys to select the menu option <rEM> and confirm with [OK].
Operation 8.8.3 Remote control device using RS232 interface The device can be remote-controlled via the RS232 interface. A null modem cable is required to connect to a PC. The device is switched off. The computer has a terminal program installed. ...
Operation Setting the timer The timer can be used to program the duration of a temperature control application from 0 to 999 minutes. The setpoint temperature is maintained for the programmed time. After the set duration has elapsed, the device switches to standby mode.
Operation 8.10 Adjusting the temperature sensor (ATC) For physical reasons, there can be a temperature difference in the bath tank between the temperature sensor and a defined, more remote point within the bath fluid volume. As a result, the measured temperature deviates slightly from the actual bath temperature.
Operation 7. In menu option <Atc>, use the arrow keys to select the correction point <Ct1> and confirm with [OK]. 8. Enter the read reference temperature and confirm with [OK]. The display flashes briefly. The correction value <Ct1> is stored at the current internal temperature value <tt1>.
1. Check the safety signs on the device for legibility and completeness. 2. Replace defective or missing safety markings. Safety signs can be reordered from JULABO. The safety signs on the device have been checked. Check the functionality of high temperature cut-off This section describes how you can test that the high temperature safety function is operational.
