Devices with and without a display are operated in different ways.
Devices without a display:
These are operated as follows:
Press both buttons for about 2 to 5 sec, briefly release them, and then press Z(ero) or
S(pan) for a further 5 – 10 sec. Press to perform the desired operation. Z then sets the 4
mA value to the acting pressure; S sets the 20 mA value to the acting pressure. It must be
ensured that the acting pressure is stable while performing either of these operations.
Devices with a display:
The menu system is self-contained. It allows you to "browse" both forwards and
backwards through the individual settings menus in order to reach the desired setting item.
All settings are permanently saved in a flash EPROM and are therefore retained even after
the supply voltage has been disconnected.
