Getting started2.
Coating thickness gauge TW-2B is designed to measure the thickness of a steel, galvanized
steel or aluminium sheet paint coating. The measurement resolution equals 10µm. The device
has a LCD backlight which makes measuring in places with insufcient light (e.g. garage) much
easier.
Before You start to use the device, please place a new alkaline battery or a fully charged accu
in the back side of the device’s housing. In order to do it please take off the battery ap and
place correctly the battery or accu by connecting it to the clips on the cable.Before You start to

Zeroing (calibration)
Before You start to take measurements, please check whether the gauge is calibrated. To do it
properly, please select the Zero function from the main menu and put the sensor against the
green side of the calibration sheet. If the display shows a 0 +/-10µm value, it means that the

gauge is calibrated. Should the aberration be larger than 0 +/-10µm, please put the sensor once
more against the green side 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 O K ...
caption and the device will return automatically to the main menu.
If the device is calibrated, You can cancel the Zero function by pressing the OK [MENU]

To take a measurement please put the device’s sensor against the examined surface. The sensor
should adhere as at as possible. The examined surface should be clean and smooth, otherwise
the measurement may be incorrect. It is advised to hold the gauge with both hands and press
gently towards the examined surface to eliminate vibration. Usually it takes 1-2 seconds to
stabilize the measurement result.
