When you reach the desired temperature decrease the CURRENT LIMIT to zero. Increase also VOLTAGE LIMIT if voltage starts limiting the output power. Observe the current and voltage increase on the power supply, temperature increase on the temperature controller and/or heater glowing through the chamber viewport. Slowly increase CURRENT LIMIT by rotating the knob. Switch the operation mode to SET CURRENT MANUALLY. Move the sample to a safe position ( not in front of the electron analyzer).Ĭheck that the CURRENT LIMIT is set to zero (fully counterclockwise).

(You can also select the unit in the e Eurotherm iTools software on the MSB-STATION computer.) Using upd/down arrow buttons set the desired unit (C, K or F).Ĭonfirm with button or discard the change with button. The double arrow symbol normally next to the set temperature will appear in front of the current unit. The temperature can be graphically monitored by the OPC Scope feature refreshed once per second. The Eurotherm unito can be also remotely controlled from the MSB-STATION computer via the iTools software.

Manuals of the Delta Elektronika SM 70-AR-24 power supply, Eurotherm 3508 controller and iTools software in PDF KEEP TEMPERATURE: the feedback loop is active, the controller is trying to keep the temperature as set by the up/down arrows by regulating the annealing current, respecting the VOLTAGE LIMIT and CURRENT LIMIT set by corresponding knobs.There are two modes of operation selectable by the switch: The scope is to measure the sample temperature (by reading the voltage of the thermocouple) and regulate the annealing current in order to reach and keep the desired temperature. The parameters of the regulation loop can be set using the iTools software provided by Eurotherm. Required currents usually do not reach 15 A, depending on the sample holder and mounting used. Alternatively, you can use a pyrometer but it would require a complicated calibration of emissivity.įor annealing we use a costom-made annealing controller containing Delta Elektronika SM 70-AR-24 power supply and Eurotherm 3508 regulator. Be aware that the error can be as high as 10% of the read temperature in ☌ or 6% in K (for example 50 ☌/K error at 500 ☌/800 K. In the latter case the real temperature might be higher. Depending on the sample materials and sample holder used, the K-type thermocouple) can be spot-welded to the sample (side or surface) or only touching it.
