Initiates an off-block electronic zero automatically, eliminating the need
for a manual zero on a specified disk or block. When the gauge is
switched on, it performs an auto zero during the boot sequence.
However, another auto zero may be needed to account for changes in
temperature, or an incorrect zero due to couplant on the end of the
transducer during the zeroing process.
Initiates an on-block manual zero. This zero is used to reset the
internal zero for of the gauge, as a reference point for the auto zero.
Note: The reference disk is located on the bottom end cap.
In order to account for very slight electronic differences in transducers
of the same type, frequency, and diameter, your gauge has a zero
coating feature. This enables your gauge to obtain very accurate
readings on coatings, eliminating potential errors incurred from slight
differences in the manufacturing processes. This zero is only used
PECT
when the
coating mode feature is being used. Although the
coating thickness is not displayed on the display, the coating thickness
is stored with the base material thickness when a measurement is
saved to memory.
Once the data is downloaded to a PC, the coating thickness will be
