*** A flashing decimal point on the lower right corner of the display will appear for 3 minutes after start-up,
calibration, bump, or programming. This is an indicator that the 4-20 mA signal is locked at 3 mA and that all
alarm functions are disabled. Once this flashing indicator clears all functions will return to normal.
Audio Enable/Disable**
This adjustment affects on-board audible alarm.
The audio enable/disable mode specifies if the audio indicator will activate
upon alarm. If disabled, all instances of audio activation will remain active
(i.e. Fault and Fail) except for gas alarms. When in this mode, the display
scrolls the message "AUDIO ON" or "AUDIO OFF" until either of the
internal
or buttons are pressed to alter the setting, or until a 3 minute
timer expires, at which time the set-up mode is aborted and the unit returns to
normal gas readings. If the
or buttons are pressed during this time, the
display reverts to a continuous text reading of "ON" or "OFF" which indicates
the selected setting. Five seconds after the last
or keystroke the scrolling
message commences with the newly selected setting.
Display On/Off
Allows user to turn the digital display on or off as required. If turned off a
decimal point will be continuously illuminated in the bottom right corner of
the display to indicate a power on condition. When “OFF” has been selected
and the instrument is in the normal run mode, user access to the Set-up mode
is achieved by following Set-up procedures.
Display Type
This mode allows the user to select between numeric gas concentrations or a
text indication of "SAFE, LOW, HIGH". When in this mode, the display
scrolls the message "DISPLAY TEXT" or "DISPLAY NUMERIC" until
either of the internal
or buttons are pressed to alter the setting, or until a
3 minute timer expires, at which time the setup modes are aborted and the unit
returns to normal gas readings. If the
or buttons are pressed during this
time, the display reverts to a continuous text reading of "TEXT" or "NUM"
which indicates the selected setting. Five seconds after the last
or
keystroke the scrolling message commences with the newly selected setting.
