Preset Calibration Methods - Elcometer 456 Operating Instructions Manual

5.2 PRESET CALIBRATION METHODS

The gauge also contains four preset calibration
methods which follow relevant standards. These
set the calibration method and the data collection
method (data collection method is only set when in
batching mode).
ISO: (ISO 19840) This uses the Zero Offset
calibration method with counted average data
collection set to 5 readings.
SSPC: (SSPC-PA2 2004) This uses the 2-Point
calibration method with counted average set to 3
readings.
SWEDISH: (SS 18 41 60) This uses the 2-Point
calibration method with counted average set to 5
readings.
AUSTRALIAN: (AS 3894) This uses the Zero
Offset calibration method with a correction value of
1/3 the surface profile peak-to-valley height and a
counted average data collection set to 5 readings.
Note: When the calibration method is changed, e.g.
from Smooth to Rough, the gauge will display a
message (Figure 28).
Figure 28. Recalibration required screen
If the NO softkey is pressed the CAL softkey
symbol on the Readings Screen will flash to warn
that calibration adjustment is still required. While
the CAL softkey symbol is flashing new batches
cannot be opened.
If the YES softkey is pressed the calibration
adjustment procedure is activated - see "Calibration
adjustment procedure" on page 27.
