Customer-Advisor Interaction: How to Calibrate a Probe without an Instruction Manual?

Client:

Hello, how do I calibrate the probe? Best regards.

Technical Advisor:

Hello, do you have the manual for your device?

Client:

No, I don't have the manual.

Technical Advisor:

What device do you have?

Client:

I have a device from the brand Regul'electronique.

Technical Advisor:

And what model?

Client:

I don't know what model I have. I just want to know how to calibrate my probe, thank you.

Technical Advisor:

Unfortunately, I don't think I have the Regul'électronique manual. Give me your email, I will check and write to you this morning. The calibration method is different for each device and explained in the manual.
