The device with 2 kinds of calibration mode,the two calibration
models are very convenient, for different customers according to
their own application to choose :
A:The standard calibration mode is provided with 0, 50, 100, 250,
500um calibration shim, it is more easy for new user, only need to
choose the corresponding calibration mode and the right calibration
shim ,then to do the calibration,it is very easy and more
B:The Multi-point calibration which could according to customer
different application of special thickness to do the calibration
operate . For example, client has standard thickness of 80um, which
different with our standard shims ,then need calibration with
7.1 Standard Calibration
Basic instruction : In the standby mode or measuring mode, long
press "MENU" key to enter the film standard calibration status,
when the display will show "CAL" logo,(the first screen will show
of “0.0 cal ” zero film calibration status), then there have 5
different calibration status ,press "+" or "-" , the five kinds of
film calibration status will be display in turn , detail
information as below :
0.0 : zero automatic calibration
50 : 50um film automatic calibration
100: 100 um film automatic calibration
250 : 250um film automatic calibration
500: 500um film automatic calibration
Calibration operate : Firstly ,long press “menu” to enter to the
film calibration interface, then select the corresponding
calibration mode of 0.0/50/100/250/500 ,via short press key “+”/
“-” ,then put the device on the corresponding film, vertically
press the device probe on the film ,and the best do 2 or 3 times
again, every time of the calibration interval should be keep for
several seconds and let the probe a little far from the metal to
keep the accuracy. The calibration operation can be repeated until
you believe it is meet your desire.
Exit the calibration : when calibration has complete, short press
"MENU" to exit the calibration status ,then it will show us to the
It is important that measuring the standard film thickness with
corresponding film calibration status . So when you find that you
run this instrument calibration status with a mistake and some
errors information shows on the display, we recommend to do the
restore of factory operate . Such as calibration 50um put the film
as 100um, the machine will display E01, buzzer continuous ring
alarm, when the sensor been lift and buzzer will stop ringing.
7.2 Multi-point calibration
When you have a standard shim which different with us, firstly
measure the shim on the Fe or NFe substrate, then get the in
initial value , then lift the instrument , and long press "+" into
the multi-point calibration interface, the screen shows "CAL". At
this point, the short press "+" or "-" can adjust the measurement
value, and the long press "+" or "-" to speed up the adjustment of
10 times. When adjusted to the standard value of the calibration
shims, the calibration is finished, then the short press "MENU" key
to exit. You can according to your detail desire to repeat this
operate to get more accuracy data.
7.3 Clear calibration data
First enter the Statistics status and enter to “Min” status (see
4.3.3) , continues press "-" key , the instrument will go to
independent restore the factory operation. When the screen shows
"000,fe,nfe,cal" and buzzer ,then keep press the key "-" for a
while till all the character displayed on the screen, it means that
the restore factory settings operate has been finished..
- 1. Before the measurement, calibration is very important to keep
the gauge in high accuracy status, zero calibration should be
carried out when you firstly use the gauge .
- 2. If you have the zero substrate of your product, the best do the
zero calibration of your own substrate then to measuring the
coating thickness .
- 3. If you calibration with wrong operate , the best way is restore
factory with long press”-”.
- 4. When the screen appears battery flag alarm, suggest to replace
the battery, otherwise the impact of measurement error, if the
instrument will not work for a long time, it is suggested to remove
- 5. If the instrument has some unusual error, take out the battery,
and keep for several minutes, then to restore the gauge, it will be
- 6. If the shim is too thin (less than 0.5mm), too small (less than
25X25mm), not recommended for measurement, otherwise the data which
will not be accuracy.
- 7. When do the calibrate and measuring operate, please keep the
probe vertically to the metal surface and during the interval ,the
best keep the probe far from the metal surface at least over 10 cm
to keep the accuracy of the device.
- 8. On the edge of the measuring surface or measuring the curvature
of the mask, it will affect the accuracy of the measurement.
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
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
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
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
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
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.
