Setting Up
Triple Plus+ and Triple Plus+ IR
OFF
Two options: OFF ENABLED, OFF DISABLED. Determines whether the instru-
ment can be switched off.
MUTE
If the mute function is enabled (which can only be done via
Portables PC
, see
section 3.5. PC interface and software) then a MUTE option will appear within
the menu system. This option can be selected as either SILENT ALARMS or
AUDIBLE ALARMS. If SILENT ALARMS is selected then the word MUTED will
flash on the main display with the gas units and name, no audible alarm will
sound when an alarm is triggered, nor will the alarm LED will flash. There will be
a visual indication of the alarm condition on the instrument’s display. Note: this
option will be ignored when the instrument’s display mode is selected as OFF.
LEVEL
This option displays and allows modification of alarm 1 for flammable LEL chan-
nels. Use the two keys labelled on the display as UP and DOWN to adjust this
alarm level between to the required value.
Note:
Crowcon does not generally recommend that alarm levels be set to a
level that is less than 5% of the sensor’s range because of the possibility of
spurious alarms being triggered.
LOG MENU
The LOG MENU acts similarly to the MENU system just described. Options are:
START or STOP.
One of these two options is displayed depending on the cur-
rent state of the data logger. Press START to turn data logging on, and STOP
to turn logging off.
USER
Allows selection of a user name, which is used in the data log (see section 3.5).
The act of changing the user is an event which is logged by the data logger.
SITE
As user, but site location.
