CHAPTER 4 COMMISSIONING
When the DMP248 transmitter leaves the factory, its 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 Selecting and scaling the analogue output quantities and
Appendix 1.
Security lock jumper
Before the settings can be changed, the user must first remove the
security lock jumper in connector X15 (see FIGURE 4-1). The security
lock jumper makes it impossible to change the transmitter settings by
mistake. The jumper should be removed only for changing the settings
and for calibration; the auto-calibration is active only with the jumper
connected. When the security lock jumper is connected, some
commands cannot be used (see Chapter Commands and security lock
jumpers).
