2.15 Powering Monitor from Charger
The monitor can be continuously powered by the charger as follows:
Important! To ensure accurate readings, the instrument must
be connected to the charger for at least 1 hour before using it
for testing purposes.
1. Turn ON the monitor without the charger attached.
Note: Connecting the charger to a monitor that is OFF
causes the monitor to enter its charging mode, which in turn
prevents the monitor from being switched ON.
2. Plug the charger into an appropriate AC wall outlet (or 12 VDC when
using the optional in-car charger). Then plug the charger’s output con-
nector in the monitor’s charging socket (Figure 1, Item I).
To turn OFF the monitor, fi rst unplug the charger—the monitor will not
turn OFF with the charger attached.
2.16 Cross Sensitivity
The monitor will exhibit some residual cross sensitivity to Carbon Di ox ide
(CO
2
). This will be in the order of 5–10 ppm N
2
O for a 1000 ppm con cen -
tra tion of CO
2
.
It is recommended that an air-cal only be done in an area where
there is little danger of elevated CO
2
levels and any traces of N
2
O.
