How can I recalibrate or check the calibration of the Cross-Hole Analyzer Depth Encoders?

The CHA manual describes a method for calibrating the Encoders, based on checking the number of pulses per a known measured length of cable. Version 2008.011L or later of the CHA program when used with data collected with CHAMP software version 2008.008N or later has an Encoder Range feature available from the Report screen, which greatly facilitates this procedure.
