Maintenance
Clean the exterior with a dry cloth.
Do not use liquid.
Battery Replacement
When "LO BATT" LED is flashing,
the battery should be replaced. Turn
your ACM4 off and replace the 9V
battery.
Check Your Sensor:
Coffee Cup CO Test
To demonstrate that your CO
sensor works, turn a ceramic coffee
cup upside down and slide it over
the edge of a counter (or desk) to
expose about a third of the mouth of
the cup. Burn a cigarette lighter inside
the exposed mouth of the cup. Don't
burn the counter.
When the flame starts to flicker,
you've burned up most of the oxygen
in the cup creating carbon dioxide
and now you're starting to produce
carbon monoxide. Bring the flame in
5. If the sensor is incorrectly installed,
"ON" LED and "LOW BATT" LED will
blink alternately and after 5sec, the
ACM4 will auto power off.
Sensor Disposal
The RCM4 Replacement carbon
monoxide smart sensor contains
sulfuric as well as precious metals. The
sensor should be recycled properly
through a local electronic waste
center.

from Fieldpiece
and out of the mouth of the coffee
cup to just keep the flame alive. The
longer you keep the flame flickering,
the more CO you produce.
After 10 seconds of flickering,
extinguish the flame and put the CO
head in the mouth of the cup. You
should see readings in the 100s. Take
it out if it approaches 1000PPM.
CO Sensor Replacement
The ACM4 uses a carbon monoxide
smart sensor. If you are seeing erratic
CO readings or no readings in a
known CO environment, you likely
need to replace the sensor.
1. Obtain replacement sensor model
RCM4 from your local distributor.
2. Remove sensor cap by removing the
4 screws.
3. Directly pull out old sensor.
4. Hold the new sensor by the sides.
While holding the sensor on the
sides; press down to secure the new
sensor. Do not press the new sensor
from the top.
