The functions performed by the control buttons are summarized in the following table: Table 2: 01 Series Control Buttons Button Function POWER/MODE • Turns the unit on and off. • Turns the LCD back light on. • Displays STEL and TWA readings (HS-01 & CO01).
Alarm Lights The 01 Series has two red LED alarm lights. They alert you to gas, low battery, and sensor failure alarms. The smaller of the two lights is square, has a frosted plastic cover, and is located at the top of the unit to the left of the membrane retainer. The larger alarm light is rectangular in shape, has a diamond-grid pattern etched into the plastic cover, and is located to the left of the LCD on the front of the case. Buzzer A solid-state electronic buzzer is mounted inside the 01 Series.
Start Up This section explains how to start up the 01 Series and to get it ready for operation. Start-up Procedure 1. Press and hold the POWER/MODE button for three seconds to turn on the 01 Series. For several seconds, all elements of the LCD display and the LCD backlight turn on. The vibrator activates briefly, and it then shuts off. The alarm lights flash on and the buzzer sounds, and then they both turn off. 2.
Operation This section describes the normal operation of the 01 Series in Measuring Mode. It explains how the unit can be used to display peak, STEL, and TWA readings for the HS-01 and CO-01, and minimum and maximum readings for the OX-01. It also covers alarm indications. Measuring Mode To put the 01 Series in Measuring Mode, assuming the unit is off, press and hold the POWER/MODE button for three seconds. Before continuing, it is advisable to perform a fresh-air adjustment in a fresh-air environment.
1. The unit must be in Measuring Mode. The current gas concentration should be displayed on the LCD. 2. Press and release the POWER/MODE button to enter Peak Gas Display Mode. The LCD backlight will activate and the LCD will display the peak gas reading. A small peak symbol is displayed in the upper left corner of the LCD. 3. Press and release the POWER/MODE button again to enter STEL Display Mode. This will display the STEL reading. The word “STEL” is displayed in the middle of the LCD above the reading.
Alarms This section covers alarm indications. It also tells you how to reset the 01 Series after an alarm has occurred and how to respond to an alarm condition. Alarm Indications The 01 Series will sound an alarm, flash its alarm lights, and vibrate when the target gas concentration rises above the low alarm point. The 01 Series also sounds an alarm, flashes its alarm lights, and vibrates when the high alarm point is reached.
Table 3: Alarm Types and Indications Alarm Type LCD Indications Other Indications Over Range Concentration of gas rises above the measuring limit of the 01 Series. (Or there could be a problem with the unit.) • Gas reading replaced by blinking brackets. • Pulsing tone occurs once per second. • Unit vibrates once per second. • Alarm light flashes. Low Battery Warning • Last remaining bar on the right in battery icon flashes. • None Dead Battery Alarm • Gas reading replaced by FAIL.
Responding to Alarms This section describes response to gas, over range, battery, sensor failure, and system failure alarms. Responding to Gas Alarms 1. Follow your established procedure for an increasing gas condition or a decreasing oxygen condition. 2. Reset the alarm by pressing and releasing the POWER/MODE button after the alarm condition has been cleared. Responding to an Over Range Alarm WARNING: An over range condition may indicate an extreme toxic gas or oxygen concentration.
possible. Refer to the instructions in “Replacing the Batteries” for more information. Responding to a Sensor Failure Alarm 1. Try calibrating the 01 Series first, as described in “Calibration”, before replacing the sensor. 2. If the sensor failure continues, replace the sensor as described in “Replacing the Sensor”. 3. If the gas sensor failure condition continues after you have replaced the gas sensor, contact RKI Instruments, Inc. for further instructions. Responding to a System Failure Alarm 1.
3. As soon as segments appear on the display (approximately one second), release the AIR button. When the unit “beeps,” release the POWER/MODE button to put the 01 Series into Alarm Point Adjustment Mode. The LCD should display the low alarm setting and the battery level. Rising Alarm .

NOTE: If you press and hold the POWER/MODE button for too long (about five seconds), you will turn off the unit. 6. Use the AIR button to change the high alarm point setting. Pressing and releasing the AIR button in quick succession increases the high alarm point one number at a time. Pressing and holding the AIR button increases the high alarm point at a faster rate.
Calibration This section covers the calibration of the 01 Series. Setting the fresh air reading is described first followed by setting the span (CO-01 and HS-01) or zero (OX-01) reading. You are also told what is needed to complete the task and how to assemble the calibration kit. WARNING: Use a 0.5 LPM (liters per minute) fixed flow regulator when calibrating. Using a different flow rate may adversely affect the accuracy of the calibration.
NOTE: On the OX-01, instead of 100% nitrogen (0% oxygen), it is allowable to use higher than 0% oxygen to set the zero level. RKI Instruments, Inc. recommends 18% oxygen or lower. • To carry out the calibration, you will need a fixed-flow regulator with a flow rate of 0.5 LPM (liters per minute), non-absorbent tubing, and the calibration adapter that will fit over the 01 Series’ sensor. Assembling the Calibration Kit WARNING: Calibrate the 01 Series in a non-hazardous environment. 1.
NOTE: If one of the control buttons is not pressed within 10 minutes, the unit will return to Measuring Mode automatically. 6. Attach the regulator to the gas cylinder. The fixed-flow regulator automatically begins introducing the calibration sample to the sensor. 7. Let the gas flow for two minutes. After two minutes, press the POWER/ MODE button. The unit will adjust the span (CO-01 and HS-01) or zero (OX-01) based on the calibration value that was saved in step 5 above.
Maintenance This section describes troubleshooting procedures for the 01 Series. It also describes how to change the 01 Series’s batteries as well as how to replace the sensor and sensor cover. WARNING: RKI Instruments, Inc. recommends that service, calibration, and repair of RKI instruments be performed by personnel properly trained for this work. Replacing sensors and other parts with original equipment does not affect the intrinsic safety of the instrument.
