4. COMMISSIONING
When the HMP260 transmitters leave the factory, their measurement ranges
and output signals have already been selected. The user can subsequently
change the measurement units between metric and non-metric and select and
scale the output signals with software functions, see Chapter 5 Commands and
Appendix 1.
4.1. Security lock jumper
Before the settings can be changed, the security lock jumper in connector X15
must be removed (see Fig. 4.1). The security lock jumper makes it impossible
to change the transmitter settings by mistake.

Fig. 4.1 Location of the security lock jumper
When the security lock jumper is connected, some commands are not available
(see Chapter 5 Commands).
Should the application require variables that are not included in the
configuration of the transmitter, the user is invited to contact Vaisala or a
Vaisala representative.
4.2 Selecting the analogue outputs
The HMP260 transmitters can be ordered ready with the current or voltage
outputs required. If the outputs need to be changed, move the jumpers in con-
nector X15 into positions as shown in the Figure 4.2.
