CHANGING THE SETTINGS
The HMI41 settings can be changed in the
SETUP
mode. It is necessary to give
the probe type setting manually if the factory settings of the indicator have
been changed or if the indicator or the probe do not have letters ID in the
instrument label.
The factory settings of the HMI41 are the following:
•
display units:
0
(metric)
•
automatic power-off:
5
minutes
•
display quantities:
0
(= RH, T, Td)
•
pressure:
1013.25 hPa
(1 hPa = 1 mbar)
(for wet bulb temperature and mixing ratio calculations)
•
probe type
AUT
(
or
1,
see below) (all/or HMP41/45)
•
start
1
(HMP41/42/45/46)
Indicators marked with letters ID have the automatic probe recognition as
default (
AUT PROBE
) and previous versions the probe type 1.
If the indicator
does not recognize the probe type automatically, set the type manually to
2 when using the HMP46.
Note also that the HMP46 probe cannot be used
with the HMI41 unless the software version is
1.02
or more. To check the
version, turn the HMI41 on with the ON/OFF button. The version appears on
the display in a couple of seconds if it is 1.02 or greater. If it does not appear,
contact Vaisala or a Vaisala representative for further information.
