Frequently Asked Questions - CRM 40 PCE Instruments
How do I calibrate the CRM 40?
Use the supplied calibration foils. Place the probe on a foil matching the expected thickness, then press the CAL button. For zero calibration, measure on an uncoated substrate of the same material.
Can I measure on both steel and aluminum?
Yes, the CRM 40 automatically detects the substrate (Fe or NFe) and switches measurement mode accordingly.
What is the measuring range?
The device measures from 0 to 2000 μm (0 – 78.7 mils). Accuracy is ±(3% + 2 μm).
How long do the batteries last?
With normal use, the two AAA batteries last approximately 30 hours. The device has an auto power-off feature to conserve battery.
Can I take measurements on rough surfaces?
Yes, but for accurate results, ensure the probe is perpendicular and make multiple readings to obtain an average.
How do I change the battery?
Slide the battery cover off at the back of the device. Insert two new AAA batteries observing correct polarity, then close the cover.
What does the 'Err' message mean?
'Err' indicates a measurement error, e.g., probe not contacting properly or out of range. Check the probe connection and recalibrate if needed.
Is the CRM 40 waterproof?
No, it is not waterproof. Keep the device dry and avoid exposure to moisture.
Can I use the gauge on plastic coatings?
Yes, as long as the substrate is metal (ferrous or non-ferrous). It measures non-magnetic coatings on magnetic substrates, and non-conductive coatings on non-magnetic conductive substrates.
Where can I find the user manual?
The manual is available for free download on notice-facile.com or the PCE Instruments website in PDF format.
