Parameterizing/adjusting/analyzing the
instrument
The analog outputs can be scaled in the following ranges, beyond the
measurement range of the measurement transmitter: -50…100°C/
-58…212°F, -50…100%RH.
The instrument is parameterized, adjusted and analyzed using the P2A
Software, see “Part 2: testo P2A Software”.
Alternatively, the 1-point adjustment can be carried out using the adapter
(accessory, 0554 6022) and a testo 400/650 with reference humidity probe.
