as per the gas selected as a flammable correction factor. For example, if there
is CH4 (methane) sensor in an instrument, and a flammable correction factor
is applied so that the instrument reads PRO (propane) then the sensor would
be selected as the CH4 (and not PRO) in the CALIB menu and methane used
to calibrate the sensor.
TIME
Selecting this will give a display of the form:
Press the key labelled HOUR to increment the hours and the key labelled
MINUTE to increment the minutes until the correct current time is displayed
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 SetPortable, see
section IX. 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 L.E.L.
channels. 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.
