1.0 INTRODUCTION
1.1 Component Identification
LCD Display: A 3-digit display provides a direct readout of oxygen
concentration in the range of 0 - 100%. The display is blank when the Handi+
enters its Sleep (power off) mode. The Handi+ will automatically enter the
Sleep mode after approximately 1.3 minutes from the last time the ON button
was pressed.
ON/OFF Button: Use this button to turn the Handi+ on and off. When the
Handi+ is in the Sleep (power off) mode, the LCD display is blank.
The analyzer turns off after 1.3 minutes if no buttons are pressed.
Calibration Button: Press the calibration (CAL) button to adjust the calibration
value to reflect the known oxygen concentration. To simplify operation, the
Handi+ Analyzer automatically determines the calibration gas being used as
room air (20.9%) or high grade (100%).
Flow Diverter: The flow diverter is designed to fit industry standard 15 mm
I.D. "T" adapters.
Over Range Indicator: The appearance of a decimal point after the first digit
means that the Handi+ is reading in excess of 99.9%.
Example: .......................................0.0.0 = 100%
..............................................0.0.1 = 101%
..............................................0.0.2 = 102%
.......(If the display reads > 0.0.3 the Handi+ should be re-calibrated.)
