PC Interface
The optically isolated RS-232 PC Interface port is located in the output/calibration
compartment situated on the lower right side of the meter. The supplied Data Acquisition
Software package includes Windows
meter-to-PC interface cable. Instructions for use can be found on the included software
CD.
Important Note on the Automatic Power OFF feature
The 407768 Sound Level Meter has an AUTO POWER OFF feature that turns the meter
off after approximately 10 minutes. This feature must be disabled before starting a
datalogging session to avoid having the meter automatically shut off in the middle of a
session. Disable it by pressing the REC MAX/MIN button to activate the Record mode.
While the meter is in the Record mode, the AUTO POWER OFF feature is disabled.
