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. The 01 Series then displays the target gas (H2S, CO, or O2) before
displaying the battery voltage. The buzzer sounds again after the
battery voltage is displayed.
CAUTION: If the unit gives a low battery warning or dead battery alarm,
change the alkaline batteries before using the unit.
3. The sensor inside the 01 Series begins operating and the concentration
of the target gas is displayed on the LCD. The 01 Series is now in
Measuring Mode. The target gas concentration is displayed. The
backlight turns off after 20 seconds.
Performing a Fresh Air Adjustment
Before using the 01 Series, set the fresh air reading. Performing this
adjustment ensures accurate gas readings in the monitoring environment.
1. Find a fresh air environment of normal oxygen content (20.9%) that is
free of toxic or combustible gases.
2. With the unit on and in Measuring Mode, press and hold the AIR button.
The LCD displays “hold” prompting you to hold the AIR button.
3. Release the AIR button when the LCD displays “AdJ”. The unit will set
the reading to 0 ppm (20.9% for the OX-01) and return to Measuring
Mode.
Turning Off the 01 Series
1. Press and hold the POWER/MODE button for about five seconds to
turn off the unit. The buzzer will sound while the POWER/MODE button
is being pressed before the unit turns off.
2. Release the button when the LCD is blank. The unit is off.
