Appendix F.  Calibration and Zeroing 
The currently measured value for the sensor will be displayed in the next 
screen.  Now place the sensor into the first known condition, and enter that 
known value into the First calibrated value box.  Press Set First Value. Wait 
for the calibration process to measure the first value.  The word Calibrating 
will be visible in the Current Value box until that process is complete.  Now 
place the sensor into the second known condition, and then enter the 
corresponding known value into the Second calibrated value box.  Press Set 
Second Value.  The calibration process measures the second point value.  At 
that point the datalogger calculates the new multiplier and offset and applies 
them within the running program.  These values are also written to the 
calibration file.
