Paint Thickness Measuring Gauges Which Widely Used for Metal Surface Coating

Basic instructions:

1 . Automatic shutdown time: 30s
2.There are 4 kinds of state mode : measurement status, Statistics status, view data
status , calibration status.
A) Measurement status: display of measured values.
B)View data status :20 sets of historical data through.
C) Statistics status: maximum, minimum, average value.
D) Multi-point Calibration status :
F) Auto Calibration status : calibration measurements, and the gauge has 6 kinds of
calibration mode of 0.0 um, 50um, 100 um,250um ,500 um.

Key function instructions
 K1 (+) function :
A :Short press K1 (+), When you in different status, it will show you different function as
below :
1) In the measurement status,short press “+”, the unit will be switch from um to mil .
2) In the view data status,short press “+”, it can turn up to show the data .
3)In the statistics status of “MAX” ,short press “+”,the background light will be off .
4)In the calibration status, short press”+”,it can switch 6 kinds of calibration mode of 0.0 um,
50um, 100 um,250um ,500 um in turn.
B: long press K1(+), When you in different status, it will show you different function as
below :
1)In the measurement status, long press “+”, it will enter to the multi-point calibration mode
2)In the view data status, long press “+”, delete a single data selected
3)In the statistics status of “MAX”, long press “+” , it could be light on /off the background
light, but if the screen is black one ,you can not see the data.
4)In the auto calibration status: exit the calibration status to the measuring status
 K2 (MENU)function
A: short press K2(menu),When you in different status, it will show you different function as
below :
1)In the Non-calibration status: measurement status, view data status and statistics status
be switched in turn.
2)In the both of auto and multi-point calibration status: exit the calibration status to the view
data status
B: long press K2(menu),When you in different status, it will show you different function as
below :
1)In the auto measurement status: enter the auto calibration status
3)In the statistics status and View data status: invalid
K3 (-)function
A: short press K3 (-)
1)View data status: turn down to show the data
2)Statistics status: invalid
3)The calibration status: switch 6 kinds of calibration mode of 0.0 um, 50um, 100
um,250um ,500 um in turn .
B: long pressK3 (-):
1)In the Measurement status: restore factory (it will removal of historical data and the
calibration parameters) .
2)In the View data status: clear the historical data (including 20 measurements, the
maximum, minimum and average), the calibration parameters keep constant.
3)In the Statistics status: invalid
4)In the calibration status: exit the calibration status to the measuring status

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 analyte ?
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 analyte 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.
