Operation Manual
TW-6s
will appear on the display. If the result is negative, the thickness of the coating is thinner than the
sample. If positive, it’s thicker.
You can use this function to measure the coating thickness on Your own material sample. In
order to do this You have to set the reference point on a clear sample sheet, the same which will
be measured afterwards.
Delete function -
Delete
Choose this function to delete all measurement values stored in the device’s EEPROM internal
memory. After deleting the stored results the device returns to the main menu automatically.
Zeroing function -
Zero
Use this function before You start to
take measurements. After choosing
this function put the sensor against
of the calibration sheet. If the display
shows a 0 +/-10µm value, it means
that the gauge is well calibrated.
Should the aberration be larger than 0
+/-10µm, please put the sensor once
more against of the calibration sheet,
wait until the result stabilizes and
press the
OK[MENU]
button while
the sensor still touches the sheet.
On the display will appear a
OK...
caption and the device will return
automatically to the main menu.

function by pressing the
OK[MENU]
button. Please note not to press the
OK[MENU]
button before the

the second line of the display – otherwise the gauge will decalibrate!.
