Code Meaning Corrective Action
E02 No sensor attached
Open the hand held nitrogen purity analyzer and
disconnect and reconnect sensor. Unit should perform an
auto calibration and should read 79.1%. If not, contact
Customer Service for possible sensor replacement.
E02 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.
E02 or ED4 Battery below minimum operating voltage Replace batteries.
CAL Err St: O
2
Sensor reading not stable
Wait for displayed nitrogen 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 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 Customer Service for
possible sensor replacement.
CAL Err Bat Battery voltage too low to recalibrate Replace batteries.
