Temperature measurement Temperature measurement 0.01 °C resolution for Pt100 and thermocouple probe Pt100 probes are generally shown with a resolution of 0.01 °C. This Optimum accuracy only applies in the environment of the calibration resolution is possible for a reading to max. +300 °C. At higher point. - Page 12 Temperature measurement Temperature measurement , k factor, quick final value extrapolation Surface correction Surface probes conduct heat from the surface being measured following the first contact.

Page 13: Humidity Measurement
The humidity probes 0636.9740 and 0636.9715 as well as 0635.1540 can be calibrated using When used with testo 400/650, the multi-function humidity probes from Testo (e.g. the hand-held instrument (no buttons on probe). All other humidity probes are adjusted using 0636.9740) show readings for relative humidity and the corresponding temperature after switch-... - Page 14 Measurement: When measuring ensure that the probe is lying firmly on the material being measured. Connecting to testo 400 or testo 650 reference instruments: If the instrument is switched on with the 0636.0565 probe attached, the instrument shows the Note: values in kΩ.
