What the product may be indicating
These are general diagnostic paths for this product category. Error-code numbers differ between brands, markets and revisions, so EgoFile shows a code only after it is confirmed in the exact official manual.
No measurement is available
Low priorityWhat it means: Range, mode, target conditions or power may be unsuitable.
First safe check: Confirm mode, reference, batteries and the stated operating range.
Stop condition: Do not proceed with drilling or cutting on an uncertain detector result.
Reading changes or will not settle
Medium priorityWhat it means: Movement, glare, temperature, surface or interference may affect the sensor.
First safe check: Stabilise the instrument and repeat from a controlled reference.
Stop condition: Use an independent method before a safety-critical decision.
Calibration warning or suspected drift
High priorityWhat it means: Impact, time or environmental change may have moved the instrument outside tolerance.
First safe check: Stop relying on results and perform the documented field check.
Stop condition: Send the instrument for calibration when the check fails.
Laser or optical output is not visible
Medium priorityWhat it means: Mode, receiver setting, brightness or contamination may be responsible.
First safe check: Check the selected mode and clean optics using the approved method.
Stop condition: Never look into the aperture or open the optical housing.
Three additional checks
Use these checks when no error code is displayed.
No reading
Check batteries, mode, range and target conditions.
Reading is unstable
Stabilise the instrument and reduce glare, vibration or temperature change.
Calibration warning
Stop relying on results and complete the official verification procedure.
