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...150%RH.
Scaling beyond the measurement range allows the adaptation of the
scaling limits to prescribed values from a PLC. The measurement range
itself cannot be extended this way.
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.
1-point adjustment with adapter
Switch on the testo 400/650. The values of the testo 6631 and reference
3
humidity probe are displayed on the left and right-hand sides of the two-
part display of the testo 400/650 respectively.
Adjust the humidity and temperature values on the reference humidity
4
probe using the Probe > Probe Adjustment menu item on the testo 400/650.
Disconnect the adapter from the interface of the testo 6631.
5
Connect testo 400/650, with
1
reference humidity probe
(0636 9741) connected, to
the interface of the testo
6631 via the adapter
(connected to probe socket
1 of the testo 400/650).
Expose the testo 6631 and
2
the reference humidity probe
to the same reference
conditions (e.g. in the
humidity generator) and
allow climatic conditions to
equalize.
