03 Series Operator’s Manual Description • 4
Sensor Gasket, Sensor Membrane, and Charcoal Filter
The sensor membrane is a paper-like filter disk that is held in place by the sensor gasket and fits into a recessed area on the inside of the front case.
The sensor membrane covers the diffusion port and protects the sensor from dirt and moisture. The sensor membrane should be inspected periodically and replaced if contaminated by dirt or moisture. See
“Replacing the Sensor Membrane and Charcoal Filter” on page 68 for sensor membrane replacement instructions.
The CO-03 includes a charcoal filter disk which is located in the sensor gasket. The charcoal filter disk removes gases from the sampled air that will cause a response on the CO sensor such as H
2
S and certain hydrocarbons. If false or elevated CO readings are noticed, especially in the presence of H
2
S, change the charcoal filter disk. See “Replacing the
Sensor Membrane and Charcoal Filter” on page 68 for replacement instructions.
Sensor
The 03 Series uses either an oxygen, CO, or H
2
S sensor. The sensor is protected by the white sensor membrane which is held in place by the sensor gasket. The sensor membrane allows ambient air to diffuse past it to the sensor. The three sensors used in the three 03 Series models use different detection principles as described below.
Oxygen Sensor
The oxygen sensor is a galvanic type of sensor. A membrane covers the cell and allows gas to diffuse into the cell at a rate proportional to the partial pressure of oxygen. The oxygen reacts in the cell and produces a voltage proportional to the concentration of oxygen. The voltage is measured by the 03 Series’ circuitry, converted to a measurement of gas concentration, and displayed on the LCD.
CO and H
2
S Sensors
The CO and H
2
S sensors are electrochemical sensors that consist of two precious metal electrodes in an acid electrolyte. A gas permeable membrane covers the sensor face and allows gas to diffuse into the electrolyte. The gas reacts in the sensor and produces a current proportional to the concentration of the target gas. The current is amplified by the 03 Series’ circuitry, converted to a measurement of gas concentration, and displayed on the LCD.
LCD
The LCD is visible through the front case. When the 03 Series is in
Measuring Mode, the target gas concentration, battery condition, and alarm indications are displayed on the LCD. Various other items are
5 • Description 03 Series Operator’s Manual
displayed when the LCD is in other modes, such as Calibration Mode.
When either of the two control buttons are pressed, the LCD backlight comes on for 20 seconds.
Control Buttons
Below the LCD are two control buttons: POWER MODE and AIR. The
POWER MODE button turns the 03 Series on and off. The functions performed by the control buttons are summarized in the following table:

Alarm LED
The 03 Series has one red alarm LED. It alerts you to gas, low battery, and sensor failure alarms. The alarm LED is located at the top of the front case beneath a clear plastic lens.
Buzzer
A solid-state electronic buzzer is mounted inside the 03 Series. An opening in the top left corner of the front case allows the buzzer’s sound to emanate from the case. The buzzer sounds for gas alarms, unit malfunctions, and the dead battery alarm. It also serves as an indicator during normal use of the various LCD display options.
Vibrator
A vibrating motor (vibrator) is mounted inside the 03 Series. The vibrator vibrates momentarily during the power-up sequence and for gas alarms.
03 Series Operator’s Manual Description • 6
IrDA Port
An infrared (IR) communications port is located just to the left of the alarm
LED at the top of the front case beneath the clear lens. The data transmitted through the port is in standard IrDA protocol. A computer’s infrared port or an IrDA/USB cable connected to a computer’s USB port can be used to download data saved by the 03 Series to a computer using the 03 Series Data Logger Management Program. See the 03 Series Data
Logger Management Program operator’s manual for data logging and downloading instructions.
Printed Circuit Board
The primary function of the 03 Series’ printed circuit board is to amplify the signal sent to it from the sensor, convert the signal to a meaningful measurement of gas concentration, display the gas concentration on the
LCD, store STEL, TWA, and peak gas readings, and activate the alarm circuit if an alarm point has been reached. It monitors battery level, battery failure, and sensor failure. It also controls various operating modes of the unit.
NOTE: The printed circuit board contains no user serviceable parts.
Batteries
Two AAA-size alkaline batteries run the 03 Series. At 25°C the alkaline batteries last at least 3,000 hours. The battery icon on the LCD shows remaining battery life.
When the 03 Series detects low battery voltage, a low battery warning is activated. When battery voltage is too low for normal operation, the 03
Series sounds a dead battery alarm.
The alkaline batteries can be replaced by removing the battery cover on the rear case. Turn the captive battery cover screw counterclockwise to release the door. See “Replacing the Batteries” on page 64 for detailed battery changing instructions.
WARNING: To prevent ignition of a hazardous atmosphere, batteries must only be changed in an area known to be nonhazardous.

Data Logging
The 03 Series features the ability to log data to its internal memory and download it to a computer via the IrDA port on the top of the case. It logs normal operation gas readings, alarm data, calibration data, and bump test data.
To utilize the 03 Series’ downloading capability, you will need the 03 Series
Data Logger Management Program and a computer with an infrared port that conforms to IrDA 1.1 protocol or a USB port that runs one of the following operating systems: Windows XP, Windows Vista, Windows 7 or
Windows 8. If your computer has an infrared port that conforms to IrDA 1.1 protocol, then no additional accessories are needed to download data from the 03 Series. If your computer does not have an infrared port but does have a USB port, a USB/IrDA adapter cable can be used to download data from the 03 Series using the USB port. The 03 Series Data Logger
Management Program is included in the product CD and is also available from RKI Instruments, Inc. The adapter cable is also available from RKI.
See the 03 Series Data Logger Management Program Operator’s Manual for a complete description of the 03 Series Data Logger Management
Program and procedures for downloading data to a computer.
03 Series User Setup Program
There are some instrument operating parameters that are not accessible in either Calibration Mode or Setup Mode such as the calibration frequency, auto zero function, and the alarm logic (latching or self resetting). Many of these parameters either do not typically need to be accessed once the 03
Series is shipped from the factory or may only need to be accessed once because of operator preferences. These parameters can be accessed and updated if necessary using the 03 Series User Setup Program, a computer with the same requirements described above in “Data Logging”, and a
USB/IrDA cable if necessary. The 03 Series User Setup Program is included in the product CD and is also available from RKI Instruments, Inc.
