DISPLAY_5_PPM_1 This option will allow theExSens X4 Instrument to display or block-off the
lower 5ppm of the measured gas value for toxic sensor 1. If blocked off,it
allows for a smoother display if the sensor has a constant moving baseline.
(Default = DISABLED).
DISPLAY_10_PPM_2 This option will allow the ExSens X4 Instrument to display or block-off the
lower 10ppm of the measured gas value for toxic sensor 1. If blocked off, it
allows for a smoother display if the sensor has a constant moving baseline.
(Default = DISABLED).
DISPLAY_5_PPM_2 This option will allow the ExSens X4 Instrument to display or block-off
thelower 5ppm of the measured gas value for toxic sensor 2. If blockedoff, it
allows for a smoother display if the sensorhas a constant movingbaseline.
(Default = DISABLED).
DISPLAY_GRAPH This option will allow the user to view a graphic display of the current gas
values detected. Each sensor port have a different color on the graphic

CAL_SETUP_PASS This option will protect the configurable setting of the instrument with a
password. When any setting is changed the user will be prompted for the
password. (Default = DISABLED).
CO_RANGE_1 This option will allow the instrument to measure toxic gas values higher
than 500ppm.This setting is for toxic sensor 1. (Default = DISABLED).
CO_RANGE_2 This option will allow the instrument to measure toxic gas values higher
than 500ppm. This setting is for toxic sensor 2. (Default = DISABLED).
DL_LIMITS This option will determine when the value for the data logging will be saved.
If the option is disabled and the measured gas value moves from the zero
point, it will be saved. If the option is enabled the measured gas value will
only be saved once the first alarm level is exceeded. (Default =
DISABLED).
MINUTE_WARNING This option if enabled, will flash the alarm LED’s at fixed intervals
(Programmable from 1 minute up to 40 minutes) to draw the user’s

timer expires. (Default = DISABLED).
CAL_REMINDER_90 This option will remind the user when the 90 day calibration due timer
