COMPUTER POLYGRAPH CALIBRATOR
Model 76740LX

DESCRIPTION

The functionality check procedures for the LX4000/LX5000 Computerized Polygraph System are performed much like the procedures followed for calibrating the Lafayette Conventional Analog Polygraph Systems.

 

Lafayette Instrument Company recommends performing Functionality Checks at a minimum of once every year, when the examiner suspects a functionality problem, when using a different LX4000/LX5000 or when the date of the last functionality test is not known.
