WARNING: Understand this manual before operating the 01 Series.
Substitution of components may impair intrinsic safety.
To prevent ignition of a hazardous atmosphere, batteries
must only be changed in an area known to be
nonhazardous. This unit has not been tested in an
oxygen enriched atmosphere (above 21%).

Introduction
Using an advanced microprocessor controlled detection system, the 01
Series Personal Single Gas Monitor detects the presence of either carbon
monoxide (CO), hydrogen sulfide (H2S), or oxygen (O2). The 01 Series’s
compact size and easy-to-use design makes it ideally suited for a wide
range of applications, including sewage treatment plants, tunnels,
hazardous waste sites, petrochemical facilities, oil fields, mines, and
chemical plants. The 01 Series is even small enough to be placed
conveniently in a pocket. The 01 Series offers the fo llowing features:
• Compact design
• Fast, accurate response with digital liquid crystal display (L CD)
• Visual, audible, an d vibration alarms
• Microprocessor control for reliability, ease of use, and advanced
• Peak, STEL, and TWA indication for CO-01& HS-01
capabilities
• Minimum and maximum indication for OX-01
• Over range alarm
• Gas, battery, sensor failure, and system failure alarms
• Over 3,000 hours operation on one set of alkaline batteries
• CSA certified for intrinsic safety in Class I, Division I, Groups A, B, C,
and D hazardous atmospheres
• Low temperature operation down to -40 °C with the HS-01S
WARNING: The 01 Series detects oxygen deficiency and elevated
levels of oxygen, carbon monoxide, and hydrogen
sulfide, all of which can be dangerous or life thre at eni ng.
When using the 01 Series, you must follow the
instructions and warnings in this manual to assure
proper and safe operation of the unit and to minimize the
risk of personal injury. Be sure to maintain and
periodically calibrate the 01 Series as described in this
manual.

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 colo r. 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 L CD (liqui d crystal display) tha t shows various
readings, which are described under “LCD” in this section. T o the left of the
LCD is an alarm light. Below the LCD are two black control buttons. The left
button is labeled “POW ER /M OD E” 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 buzze r is the senso r . The senso r is held in
place by the senso r re tainer (the top of the case for th e 01 Series) and two
screws. The sensor is prote cted from dirt and m oisture by the sensor cover .
The sensor cover is secured by a membran e 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.
