6.0 CALIBRATION ERRORS AND ERROR CODES
The N2 analyzers have a self test feature built into the software to detect faulty
calibrations, oxygen sensor failures, and low operating voltage. These are listed
below, and include possible actions to take, if an error code occurs.
E03: No valid calibration data available
Make sure unit has reached thermal equilibrium. Press and hold the
Calibration Button for three seconds to manually force a new calibration.
E04: Battery below minimum operating voltage
Unit is at end of life, see page I for proper disposal.
CAL Err St: O2 Sensor reading not stable
Wait for displayed oxygen reading to stabilize when calibrating the device at
100% oxygen. Wait for unit to reach thermal equilibrium (Please note that this
can take up to one half hour, if the device is stored in temperatures outside the
specified operating temperature range).
CAL Err lo: Sensor voltage too low
Press and hold the Calibration Button for three seconds to manually force
a new calibration. If unit repeats this error more than three times, contact
Maxtec Customer Service for possible sensor replacement.
CAL Err hi: Sensor voltage too high
Press and hold the Calibration Button for three seconds to manually force
a new calibration. If unit repeats this error more than three times, contact
MAxtec Customer Service for possible sensor replacement.
CAL Err Bat: Battery voltage too low to recalibrate
Unit is at end of life, see page I for proper disposal.
7.0 CLEANING, MAINTENANCE, AND DISPOSAL
Store the N2 analyzer in a temperature similar to its ambient environment of
daily use. The instructions given below describes the methods to clean the
instrument, sensor and its accessories:
Instrument
•
When cleaning or disinfecting the exterior of the N2 analyzer, take
appropriate care to prevent any solution from entering the instrument.
Do not immerse unit in fluids.
Oxygen Sensor
•
Clean the sensor with a cloth moistened with a 65% alcohol / water solution.
•
We do not recommend use of spray disinfectants because they can contain
salt, which can accumulate in the sensor membrane and impair readings.
Do not throw away. Dispose of properly in accordance with local regulations.
