View Full Version : Temperature probe calibration data correct?

So I have purchased a Profilux Plus II.
To clean it up I have started it up with a jumper according to the GHL manuel.
After (finally) fixing the driver bug the RS232-USB connection succeeded.
Firmware has been updated to the youngest available version.
Connection via Profilux Control is successful.

Now it is time to start using the potential of this device.
First, and probably most easy, is the temperature control setup:
Nominal 24oC
Cooling diff. 26oC
Hysteresis 0,2 SUP]o[/SUP]C
(in order to have the heater running between 23,9~24,1 and the cooler running between 25,9~26,1)
All be it not to difficult to realise.

Now to the questions:
Since this device and all its belongins are second hand equipment I have no original documentation on the calibration data of the temperature probe.
In the settings (see attached picture) are calibration data prefilled for 20SUP]o[/SUP]C and 30 SUP]o[/SUP]C.
Are these correct calibration settings?
How can I be sure this is correct?
And if this is not correct how can set them correct?

Any reply is much appreciated.

Hello,

you should always re-calibrate after several weeks (2-4), in order to have a reliable system.
Use the calibration fluids and follow the manual for your ProfiLux 2, which you can download from here:
