is indicated on the display for a few seconds and the M2 Rig Monitor
returns to normal operation.
A2 OffDy (alarm 2 off delay)
(0 sec.) The amount of time the Rig Monitor delays turning off the alarm 2 circuit
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 setting for the H
2
S detector is 2.0
ppm, the Rig Monitor will display a reading of 0 ppm for gas readings
from -2 ppm to 2 ppm.
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 previous 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 button push
while in Calibration Mode that the Rig Monitor will wait before returning to
normal operation. If the calibration time-out is set to 15 mins, then Rig
Monitor will return to normal operation automatically 15 minutes after the
last button push.
Auto Zero
(Enabled) If set to Enabled, the Rig Monitor’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.
