1) How the coating thickness gauge shut down?
A: Our coating thickness gauge adopt with automatic shutdown, when you stop using it, it will be shutdown automatic after 30 seconds.
2) What angle should be kept with Coating thickness with the substrate ?
A: The probe must be kept perpendicular to the surface with the measured material, otherwise it will lead to considerable error.
3) How to maintain accuracy of measurement when we need repeatedly measurements ?
A: When we need repeatedly measure, the thickness gauge should be keep the distance more than 3cm away from the substrate and at least keep 2 seconds or more interval .(Attention :Do not drag along the surface to the side of the probe to avoid probe magnetization.it will be impact of next measurement result)
4) When should we to calibrate the Coating thickness ?
A: Our thickness gauge has been calibrated , in most time, we just need to check whether the uncoated substrate is normalized to
zero .Usually when the measurement accuracy beyond the precision values ,it need to be calibrated (refer to the instructions
precision value range) . Calibration method according to operating instructions.
5) When the Coating thickness display with"" ,What does it mean?
A: It indicates that the battery voltage is low, please replace the battery in the automatic shutdown, otherwise it will affect
the measurement accuracy.
6) How to choose the zero substrate?
A: The thickness of zero substrate should be used as the test material to avoid the permeability of different materials and
measurement errors.
7) How to choose the zero substrate surface?
A: Use the gauge should be in the same part of the material being tested after calibrating to zero, and then measuring the same
part. If the measuring pipe, bar and other curve surface materials, but the user indeed calibrating to zero with substrate of
flats surface , this will affect the accuracy of the measurement. And choose the calibrating zero surface should be more smooth.
8) Coating thickness gauge has been calibrated, why also the measurement also not accurately?
A: The coating thickness calibration could not choose the substrate random ,firstly calibrating to zero based on the same test
material of substrate which without coating , then put the calibration sheet in the top to calibrate, so that could get reliable
measurement data. Remember: Be sure to use the same shape, the same material, the same roughness zeroing calibration substrate.
9) Why the different coating thickness measured data is not the same?
A: Due to different coating thickness gauge calibrated with different substrate before use . For consistency, we should make them in the same uncoated substrate to do the zero calibration, and then put the calibration sheet in the top to calibrate, so
different coating thickness measurement data will be keep consistent.
10) When should we to replace to Standard film ?
A: The coating thickness calibration depends on the calibration sheet, so it is very important that keep the calibration sheet in
good condition. If the calibration sheet has been used for many years and not in a good condition, please replace it . Otherwise,
the measurement data will be inaccurate.
