Putting the ERX Recorder into “Shutdown”
Shutdown is a mode of operation invoked by the user prior to placing the instrument into storage
or prior to performing some type of board maintenance. The MasterLink32 Link software
manual describes the procedure for putting the ERX Recorder into shutdown. There are two
types of “Shutdown” that can be induced into the ERX Recorder; Partial and Complet
e. The
connection status of the battery packs determines which type of Shutdown the instrument
assumes.
Partial Shutdown
To put the ERX Recorder into “partial shutdown”, from MasterLink32 Link software, select and
confirm “SHUTDOWN” from the “Instrument” menu. Leave the main battery plugged-in.
In partial shutdown, the recorder’s real-time clock will continue to update; however, the sampling
of pressure or temperature of the gas no longer occurs. The LCD will show dashes “- - - - - - - -
“across the display. The recorder still draws normal background current from the main battery
when placed in partial shutdown, and it preserves all item values and audit trail information.
To recover from a partial shutdown, i.e., return to Sample Mode, simply press the MI button.
Complete Shutdown
To put the ERX Recorder into “complete shutdown”, from MasterLink32 Link software, select
and confirm “SHUTDOWN” from the “Instrument” menu, then unplug the main battery, and
remove the super cap jumper. In complete shutdown, the clock of the recorder will stop working
and the sampling of pressure or temperature of the gas no longer occurs. The configuration data
of the recorder and all item va
lues are retained in E
2
PROM. The LCD display will go blank once
the batteries are unplugged.
In order to bring the ERX Recorder out of a complete shutdown, simply plug in the main battery
and replace the super cap jumper. It will be necessary to reset the date, time, and other items that
are not current.
