Symptoms

Multiple GENIUS 2 thermometers fail recalibration

Multiple thermometers do not pass calibration or show inconsistent results during checker operation.

Ranked causes

1. Probe cover stuck in blackbody target (occasional)
2. Dirty probe cover (common)
3. Dirty thermometer lens (occasional)
4. Thermometer not seated correctly in target (common)
5. Equipment not at thermal equilibrium with room temperature (occasional)

First check

Inspect for stuck probe covers in targets

Test point: Blackbody target openings
Expected: No probe covers visibly stuck; targets clear

Test report does not write to USB flash drive

Report file fails to save to USB flash drive when selected at end of calibration.

Ranked causes

1. USB flash drive not formatted (common)
2. USB flash drive write protected (common)
3. Insufficient free memory space on USB drive (occasional)
4. USB flash drive incompatible with GENIUS 2 Checker/Calibrator (occasional)
5. Insufficient initialization time for USB drive detection (occasional)

First check

Verify USB flash drive is formatted and write protection disabled

Test point: USB drive properties on PC
Expected: Drive formatted; write protection off

GENIUS 2 Checker/Calibrator will not power up caution

Unit does not turn on or respond when AC power is applied.

Ranked causes

1. Not receiving AC power (common)
2. Blown fuse (occasional)

First check

Verify AC power connections

Test point: Power cord and AC outlet
Expected: Cord seated firmly in outlet and unit connector

Error 6 repeatedly appears while testing same GENIUS 2 thermometer

Error 6 (Ambient Temperature Out of Range) message displays repeatedly for single thermometer during testing despite ambient conditions being correct.

Ranked causes

1. Potential power consumption issue with thermometer (rare)

First check

Test with different GENIUS 2 thermometer

Test point: Alternative thermometer unit
Expected: No Error 6 message with alternate thermometer under same ambient conditions

GENIUS 2 thermometer seems to read high or low following successful recalibration

Thermometer readings are outside expected accuracy range after completing calibration check and recalibration.

Ranked causes

1. Probe cover reused during calibration (common)

First check

Verify new probe cover used for each calibration insertion

Test point: Probe covers used during procedure
Expected: One new cover per target insertion; no reuse
