Gauge Calibration
1. Select Gauge Calibration and click the Next button to advance to the following
screen.
Figure 3-16. Gauge Calibration
This screen asks for two pieces of information – the type of calibration to be
performed and the calibration sample time, in seconds.

CAL Method – The DensityPRO gauge can perform two types of calibration.
A polynomial calibration typically only requires basic gauge information and
one calibration point to calculate a calibration curve. This is the most
common type of calibration method used in Thermo Fisher density gauges,
and, unless otherwise advised, utilization of this calibration method is
recommended.
In some instances a polynomial method may not be the most ideal method of
calibration. For those instances, a breakpoint table is available to establish the
calibration curve.

CAL Sample Time (sec) – Like the standardization time, the calibration time
is a period, measured in seconds, during which the instrument will average the
detector counts. Again, the sample time should be based on process
conditions. Typical calibration sample times run between 300 and 900
seconds.
