3. Take a reading by pressing the READ/SELECT key.
4. Compare the reading for the angle chosen with the gloss
value of the tile at that angle - look for the sticker inside the
calibration tile case.
If the reading taken by the gauge matches the gloss value
of the tile, the gauge is within calibration limits and is ready
for use.
If the reading taken by the gauge does not match the gloss
value of the tile, calibrate the gauge - see "Calibration" on
page 14.
3.2 TO TAKE A MEASUREMENT AT A SINGLE POSITION
1. Position the gauge using the arrows on the front and side to line up with the area to be measured.
2. Dual angle models only: In measurement mode, select the required angle, pressing the C key to cycle
through the angles 20 > 60 > 20/60.
3. Press and release the READ/SELECT key. The gauge will now start to take a reading and >> will be
shown on the display.
