If the basic settings of the HMI41 (display units, automatic power off
function, display quantities and pressure) have to be changed, please refer to
the HMI41 Operating Manual. Otherwise, press ENTER repeatedly until the
following text appears:
set
The number on the first line of the display corresponds to the following
HMI41 functions:
1 = HMI41 as a humidity and temperature indicator
2 = HMI41 as a calibrator for HMD/W60/70 and HMP140 series analogue
transmitters
3 = HMI41 as a calibrator for HMP230 series digital transmitters
4 = HMI41 as a calibrator for the HMD/W20/30 and HMP130 series
analogue transmitters
To calibrate the HMD/W60/70 or the HMP140 series transmitters, select
number 2 with buttons ▲ (number up) and ▼ (number down) and then turn
the HMI41 off. When the HMI41 is turned on again, it will automatically
wake up as a calibrator for these analogue transmitters. If you wish to calibrate
transmitters of some other type or use the HMI41 as an indicator, this
selection has to be done accordingly; refer to corresponding manuals for
further details.
Note that if the default settings in the HMI41 memory have not been changed
(e.g. when it is used as a calibrator for the first time), the HMP140 series
transmitters with standard settings and voltage outputs can be directly
calibrated (see Chapter 3). In all other cases scale selections are necessary;
please, consult Chapter 2. The default settings in the HMI41 memory (Table
1.2) are returned with U, I, cU or cI selections according to which changes
have been made.
