Calibration
Periodic calibration—channel #1 functions
Periodic calibration overview
Periodic calibration adjusts the system by resetting one point of the calibration curve to an
independently measured or known sample.
The frequency of periodic calibration depends on several factors, including desired accuracy
of the reading.
Periodic calibration consists of five steps:
1. Adjustment of zero reading by using the Simple Re-Cal function
2. Checking the absorber value by performing a simple data collect. Cal Hi on absorber if
absorber value reads off by an unacceptable amount
3. Empty the belt and perform a simple data collect if the gauge is still not reading the
product correctly.
4. Empty the belt and reset the absorber value
5. Save re-cal to EEPROM.
Smart Pro Note: Refer to the "Smart Pro Reference Chapter 3, section Re-Cal / Channel #1
(Category II Functions)" for more information about choosing a method and performing the
periodic re-cal.
If the calibration is not accurate after performing a zero and recalibration on absorber, then
perform a Cal Hi to verify that the gauge is reading correctly. After the gauge is reading
correctly, have the gauge detect an empty belt condition with the absorber in place, for the
correct high value for the absorber. The new value should be re-entered at screen 159.
