Frequently Asked Questions
What does the limit alarm do?
▾
The programmable limit alarm lets you set a maximum or minimum thickness value. When the measured coating exceeds or falls below that threshold, the gauge emits an audible beep and flashes the display, allowing you to instantly identify out-of-spec areas without pausing the inspection.
Does the gauge work on non-metal surfaces?
▾
Yes, the ultrasonic sensor can measure thickness on wood, plastic, and composite materials as long as the surface is solid and the coating adheres. The gauge automatically adjusts its reading algorithm, but extremely soft or porous substrates may produce slightly less consistent results compared to metal.
How is the battery charged?
▾
The CT1500G uses a built-in lithium-ion battery that charges via the supplied USB-C cable. Connect the gauge to a wall adapter or computer USB port; a full charge takes about two hours and provides up to eight hours of continuous operation before recharging is needed.
Is the device calibrated out of the box?
▾
The device ships calibrated from the factory and is ready for immediate use. For critical applications you can perform a quick verification using a certified step gauge, but no additional calibration steps are required for standard automotive or industrial coating measurements.
Can the gauge store multiple threshold settings?
▾
Yes, the CT1500G allows you to save up to three separate limit values in its memory. You can quickly switch between them using the function button, which is useful when inspecting different coating specifications on the same job without re-entering the limits each time.
