5-1-1. Introduction
Standard operation of the EXA instrument involves use of the Maintenance (or operat-
ing) mode to set up some of the parameters.
Access to the maintenance mode is available via the six keys that can be pressed through
the flexible window in the instrument front cover. Press the “MODE” key once to enter
this dialog mode.
(Note that at this stage the user will be prompted for a pass code where this has been
previously set up in service code 52, section 5.)
Setpoint
Select and adjust setpoint (when enabled in service menu section 5-3,
service code 51). See adjustment procedure 5-2-2.
Calibrate
See “calibration” section 6.
Display setting
See “operation” section 4.
Hold
Manually switch on/off “hold” (when enabled in commissioning
menu). See adjustment procedure 5-2-4.
Note :
If no key is operated for 10 minutes in any mode other than measurement mode or after
10 minutes in Hold status, Auto-Return (factory setting: On (1) in service code 50) will
be activated to return the converter to measurement mode. To disable Auto-Return, set
the service code 50 to Off (0) .
WARNING
If you disable Auto-Return function then the transmitter does not automatically return to
Measurement Mode. You need to press [MODE] key to return to Measurement mode.
