SEFRAM 720, BK 720 User manual

Hello! I have reviewed the BK PRECISION 720 user manual. This document provides instructions and specifications for the Humidity Temperature Meter. It covers features such as dual temperature channels, humidity readings, thermocouple support, data hold, max/min values and relative mode, and also the RS-232 data output. I'm ready to answer your questions about the device.
What type of thermocouple does the meter support?

What is the humidity measurement range of this device?

How long does the auto power off work?

Does the meter support data hold?
