Power for the Electronic Test Set is provided through the multi-channel (MULTI-CH) connector located on the back of
the unit. In addition, this connection interfaces ACCELEROMETER channels 5-14, TACHO channel 2 and TRACKER
channel 2. Proper connection is obtained when the INTERNAL POWER LED is illuminated.
Calibration of the DAU is performed using a Personal Computer (PC), Control and Display Unit (CADU), the DAU, and
the appropriate cables. A printer is optional.
The procedure to verify the calibration of the DAU is achieved by programming the CADU with the supplied software
via a PC. Calibration checks are performed automatically by executing the internally stored program downloaded to
the CADU. Data from the CADU is then compared with the specifications in this manual. If desired, the user may
produce a hard copy of the results if a printer is connected to the system.
