Making the instrument ready for operation
1.3.3.1
Surface preparation
Carefully clean the surface of an inspected object from dirt, friable rust, and scale before
measurements. Apply a sufficient amount of the lubricant to the area of inspection.

Switching On/Off the instrument
To switch on the thickness gauge, shortly press the
key.
On the instrument's screen, a moving message with the manufacturer name and
firmware version is displayed for several seconds.
The instrument will switch into the measurement mode. The horizontal strokes, the
accumulator battery state, and the current measurement units are displayed on the
screen.
To switch off the thickness gauge, press and hold the key for more than two seconds.
The instrument will automatically switch off in 5 minutes if neither keys are pressed, nor
the measurement process goes.
1.3.3.3
Select the measurement units
Select the measurement units: metric or imperial.
METRIC ("mm" shall be indicated) – the instrument measures the thickness in mm; the
instrument uses m/s for velocity.
IMPERIAL ("in" shall be indicated) – the instrument measures the thickness in inches (in);
the instrument uses inch/ms (in/ms) for velocity.
To select the measurement units, while switching on the instrument, press and hold the
key until the screen changes the displayed measurement values from "mm" (metric
system) to "in" (imperial system) or vice-versa.
