Page 16: Operating Instruction
CALsys 250 7. Operating Instruction: 7.1 Power Plug the calibration bath power cord into mains outlet of the proper voltage, frequency and current capability. Typically this will be (230 VAC±10, 50/60 Hz). Turn the controller using the “Mains” switch located on the controlling section and set the temperature value in the controller. -
Page 17: Operating Instruction
Directly, First set the controller to 0 Deg C and then wait until the unit is not cooled below 100 Deg C. 7.3 Operating Instruction: 1. Connect the ‘CALsys 250’ to a suitable power supply. 2. Fill the oil in the bath, up to the marked line, Connect the power Supply to the heater and stirrer. - Page 18 11. When the calibration is completed, reset the controller to 0°C & wait until the unit has cooled to below 100°C, before moving the ‘CALsys 250’ to new location the ‘CALsys 250’ must be cooled to below 100°C.

CALsys 250 8.6.3 How to know Auto tune has done: Whenever ‘AUTO TUNE’ is ‘ON’ there will always be a rolling message ‘AUTO TUNE’ on display of controller. When the display is not showing this continues message it means Auto tune is complete. - Page 23 CALsys 250 9. Digital Communications: RS-232 is a standard communication protocol for linking computer and its peripheral devices to allow serial data exchange. RS-232 communications uses the Modbus protocol. Rs-232 communications is not available if Remote Set point is fitted. Cable screen should be grounded at one point only to prevent earth loops.
- Page 24 CALsys 250 9.1 Digital Communications Wiring To use EIA232 the PC will be equipped with an EIA232 port, usually referred to as COM 1.To construct a cable for EIA232 operation use a three core screened cable. The terminals used for EIA232 digital communications are listed in the table below. Some PC's use a 25 way connector although the 9 way is more common.

Page 31: Maintenance & Trouble Shooting
CALsys 250 12. Maintenance & Trouble shooting:- 12.1 Routine service: Turn the electricity supply off before attempting any cleaning operation. The only moving part is the fan. That has sealed-for-life bearings. Depending on the environment in which it is used, periodic cleaning is recommended. Cleaning may be accomplished by the use of a small dry paint brush. - Page 32 CALsys 250 6. Tighten the fixing screws. 7. Refit the wires has been noted in step 4. 8. Replace the cover. 9. Reconnect the furnace to the electrical supply. NOTE: The calibration instrument has been designed with the utmost care. Ease of operation and simplicity of maintenance have been a central theme in the product development.
- Page 33 CALsys 250 It is important to keep the well of the calibrator clean and clear of any foreign matter. DO NOT use chemicals to clean the well. The bath should be handled with care. Avoid knocking or dropping the instrument.
