Maintenance
This instrument is precision-machined. Never drop it or knock it over.
Always clean the instrument after use.

How to Perform a Measurement
Measuring Roughness
Press the On/Off button to switch the gage on.
Check if the right tip is chosen. (the sharp needle tip is suitable for measuring roughness)
Choose parameter by pressing the IN/MM button.
Place the needle of the gage on the flat glass specimen (zero plate) and press the gage with the
holder down until the base of the holder stands firmly on the zero plate.
Press the ZERO button to make the instrument read zero.
Place the needle gently on the blasted surface and press the base of the gage-holder firmly against
the steel. DO NOT drag the instrument.
Read the peak-valley value.
Make 10 measurements on each desired location and determine the mean as being the profile of
the surface.
Measuring Thickness
Press the On/Off button to switch the gage on.
Check if the right tip is chosen. (the round tip is suitable for measuring thickness)
Choose parameter by pressing the IN/MM button.
Place the needle of the gage on the flat glass specimen (zero plate) and press the gage with the
holder down until the base of the holder stands firmly on the zero plate.
Press the ZERO button to make the instrument read zero.
Gently remove a piece of paint with a diameter of 8mm. from the surface. Try to remove the paint
without damaging the underground material.
Place the needle on the removed paint. Make sure the aluminum footing stands on the painted area.
The Coating thickness appears on the display.
Changing Tips
Step 1
Two tips are supplied. The sharp needle tip is suitable for measuring roughness, the round one for thickness.
Step 2
Take the tip between two fingers and turn anti-clockwise until it is loose. If the tip stays stuck, go to step 2a.
Step 2a
Only when loosening the tip anti-clockwise by hand fails, a pair of tongs may be used GENTLY. Make sure the tip remains undamaged.
Step 3
Turn the new tip clockwise until it’s stuck.
Step 4
The tips have been changed. Don’t forget to store the tip that’s not in use.
