Protective Rubber Boots
A protective rubber boot is installed over each end of the 01 Series. The
sensor end boot fits over the sensor cover end of the 01 Series and the
battery end boot fits over the battery cover end of the 01 Series.
Case
The 01 Series’ sturdy, high-impact plastic case is blue in color. The case is
suitable for use in many environmental conditions, indoors and out. The
unit is dust proof and weather resistant.
The front of the case has an LCD (liquid crystal display) that shows various
readings, which are described under “LCD” in this section. To the left of the
LCD is an alarm light. Below the LCD are two black control buttons. The left
button is labeled “POWER/MODE” and the right button is labeled “AIR”.
On top of the case and to the left is the 01 Series’s buzzer, which is located
inside the unit. To the right of the buzzer is the sensor. The sensor is held in
place by the sensor retainer (the top of the case for the 01 Series) and two
screws. The sensor is protected from dirt and moisture by the sensor cover.
The sensor cover is secured by a membrane retainer and a single screw. In
the case of the CO-01, a charcoal filter is provided under the sensor cover
to protect the CO sensor from hydrogen sulfide and certain hydrocarbons.
To the left of the sensor and below the buzzer, is a second alarm light,
which is also visible from the front of the case.
The battery compartment is located on the bottom of the case. Access to
the compartment is accomplished by turning the captive battery cover
screw counterclockwise and by removing the battery compartment door.
There are two threaded holes on the back of the case. These are used to
mount the optional alligator clip or belt clip.
Toward the bottom of the back are two battery charging contacts. These
contacts are used to charge a Ni-cad battery pack which is available.
Consult RKI Instruments, Inc. for information about this option.
The wrist strap connects to the back of the case on the left side, near the
top of the unit.
