2.5 TAKING A MEASUREMENT
2.5.1 Zeroing the gauge
Each Elcometer 550 Non-Contact Uncured Powder Gauge is individually calibrated at the factory. To
ensure the highest level of measurement accuracy the Elcometer 550 should be zeroed by the user, before
use, to take into consideration the varying environmental conditions.
To zero the gauge:
• Take the circular zero reference block from the case and check that the inside is clean and free from
dust
• Position the sensor gun vertically so that the top of the measurement head is pointing vertically
upwards and place the zero reference block over the top
Note: The zero reference block fits loosely on to the sensor gun and will fall off if not held vertically.
