Preparing for Start Up
1. To remove the battery compartment cover, place the Innova upside
down, turn the large screw counterclockwise until it is loose in its
socket, then pull up.
2. Install four “D” size batteries according to the diagram inside the
battery compartment. Make sure that the battery polarities are
correctly oriented.
NOTE
Make sure the slide switch at the bottom of the battery compartment is
set to
“ALK”
for
alkaline
or “
NI-CAD”
for
NiCd batteries,
see
Chapter 6, Maintenance, Figure 6-1, Innova Battery Compartment.
3. Replace the battery compartment cover and turn the screw clockwise.
Tighten snugly to compress the gasket and seal the battery compartment.
CAUTION
Some toxic gas sensors require up to 15 minutes to stabilize, after
you install the batteries. If your Innova includes a toxic gas
sensor(s), do not turn on and use the Innova during this period. If
the unit is started up immediately after installing batteries, the
“BIAS” message may appear, see Chapter 6, Maintenance, for
instructions on installing or recharging batteries.
4. Verify that the hydrophobic filter and cotton ball are in good condition
and installed properly in the probe body.
NOTE
For transformer versions, connect the dilution fitting directly to the
disconnect coupler fitting on the front of the monitor, then connect the
10-inch probe to the dilution fitting.
5. Attach the probe to the female disconnect coupler fitting on the sample
hose.
6. Attach the other end of the hose to the female disconnect coupler on
the front of the instrument.
