CONFIGURATION MODE
3.1 ENTRY INTO CONFIGURATION MODE
To enter Configuration Mode:
1. Ensure that the instrument is powered-down.
2 . Power-up the instrument and, within ten minutes of power-up, hold down
the Raise and Scroll keys simultaneously for six seconds. If this is done
whilst the instrument is displaying the process variable value, the instrument
will enter/exit Set Up Mode - keep holding the keys down!
NOTE: This need not be the first key action after power-up.
The instrument will then enter Configuration Mode and the SET indicator will flash. The
user will then be presented with the first of a sequence of parameter displays; in each
instance, the parameter will be identified by a single-character legend in the units
display and the setting of that parameter will be shown in the four-digit display. The
user may then step through the parameters using the Scroll key. The setting may be
adjusted using the Raise/Lower keys. As soon as the value/setting is changed, the
four-digit display will flash, indicating that the new value/setting has yet to be confirmed
(this flashing is inhibited during actual adjustment). When the value/setting is as
required, it may be confirmed by:
(a) press ing the Scroll key, where upon the four- digit dis play will show:
(b) press ing the Raise key.
The four-digit display will then show a static (non-flashing) display of the new parameter
setting. Depression of any key other than the Raise key at the SurE? display will cause
the original parameter setting to be retained. The sequence of parameter displays is
shown in Table 3-1.
NOTE: Changes to the value/setting of certain Configuration Mode
parameters (e.g. input range, output use and type) will cause the Set
Up Mode parameters to be automatically set to their default values the
next time Set Up Mode is entered (see also Volume 1, start of Section
3). It is recommended that all Configuration Mode parameters are
finalised before Set Up Mode parameters are adjusted.
