A2 OffDy (alarm 2 off
delay)
(0 sec.)
The amount of time the M2A delays turning off the alarm 2 cir
-
cuit once an alarm 2 condition passes. This parameter appears
only if the alarm 2 relay reset setting is set to
SELF-RST
. It can
be set in 1 second increments from 0 - 60 seconds, in 1 minute
increments from 1 - 15 minutes, and in 15 minute increments
from 15 - 60 minutes.
ZeroSupp
(2 ppm)
The zero suppression feature helps prevent “jumpy” readings near
the fresh air reading.
For example, if the zero suppression is
2.0 ppm,
the M2A will
display a reading of 0 ppm for gas readings from -2 ppm to 2
ppm. It is settable from 0 to 6% of the detection range.
FILTER
(5 secs)
The filter feature helps “smooth out” jumpy or noisy signals from
the detector. You can set the filter from 0 seconds to 60 seconds in
5 seconds increments.
The displayed gas reading is the average reading over the previ
-
ous time period defined by the filter setting. So if the filter is set
to 5 seconds, the displayed gas reading is the average over the
past 5 seconds.
CAL Time
(15 mins)
The calibration time-out sets the amount of time after the last but
-
ton push while in Calibration Mode that the M2A will wait before
returning to normal operation. If the calibration time-out is set to
15 mins
, then M2A will return to normal operation automatically
15 minutes after the last button push.
Auto Zero
(Enabled)
If set to
Enabled
, the M2A’s firmware will monitor the zero
(fresh air) reading and make automatic zero adjustments under
precisely specified conditions if it determines that a reading
change is due to normal sensor drift.
If set to
Disabled
, the Auto Zero function is turned off.
