Before use, all individuals who will be using the MAXO

2

®

+

must become thoroughly
familiar with the information contained in this Operation Manual. Strict adherence
to the operating instructions is necessary for safe, effective product performance.
This product will perform only as designed if installed and operated in accordance
with the manufacturer’s operating instructions.

Use only genuine Maxtec

®

accessories and replacement parts. Failure to do so

may seriously impair the analyzer’s performance. Repair or alteration of the

MAXO

2

®

+

beyond the scope of the maintenance instructions, or by anyone other
than an authorized Maxtec®service person, could cause the product to fail to
perform as designed.

Calibrate the

MAXO

2

®

+

weekly when in operation, or if environmental conditions
change significantly. (ie, Elevation, Temperature, Pressure, Humidity — refer to
Section 3.0 of this manual).

Use of the

MAXO

2

®

+

near devices that generate electrical fields may cause erratic

readings.

If the

MAXO

2

®

+

is ever exposed to liquids (from spills or immersion) or to any
other physical abuse, turn the instrument OFF and then ON. This will allow the
unit to go through its self test to assure everything is operating correctly.

Never autoclave, immerse or expose the

MAXO

2

®

+

(including sensor) to high
temperatures (>70°C). Never expose the device to pressure, irradiation vacuum,
steam, or chemicals.

NOTE: Replace the batteries with recongnized high quality AA Alkaline or Lithium batteries.

NOTE: If the unit is going to be stored (not in use for 1 month), we recommend that you
remove the batteries to protect the unit from potential battery leakage.

FAILURE TO COMPLY WITH THESE WARNINGS AND CAUTIONS COULD RESULT IN
INSTRUMENT DAMAGE AND POSSIBLY JEOPARDIZE THE WELL BEING OF THE
PATIENT AND/OR HEALTH CARE PROFESSIONAL.

1.0 SYSTEM OVERVIEW

1.1 Base Unit Description

The MAXO

2

®

+

analyzer provides unparalleled performance and reliability due
to an advanced design that includes the following features and operational
benefits.

• Extra-life oxygen sensor of approximately 900,000 O

2 percent hours

(2-year warranty)

• Durable, compact design that permits comfortable, hand-held operation

and easy to clean.

• Operation using only two AA Alkaline batteries (2 x 1.5 Volts) for approxi-

mately 5000 hours of performance with continuous use. For extra extend­ed long life, two AA Lithium batteries may be used.

• Oxygen-specific, galvanic sensor that achieves 90% of final value in

approximately 15 seconds at room temperature.

• Large, easy-to-read, 3 1/2-digit LCD display for readings in the 0-100%

range.

• Simple operation and easy one-key calibration.

• Self-diagnostic check of analog and microprocessor circuitry.

• Low battery indication.

• Calibration reminder timer that alerts the operator, using a calibration icon

on the LCD display, to perform a unit calibration.
