Making a Measurement
In this chapter we describe how to make and store an
accurate sound level measurement. Before doing this,
make sure that the Model 831 has been setup to meet the
requirements for the measurement as described in
Chapter 4 “Basic Measurement Setup” on page 4-1.
Configuration of the System
The System Model 831 should be configured with the
preamplifier connected to the front of the instrument and the
microphone connected to the end of the preamplifier.
Switching On the Model 831
Do not use the hardware power
switch to turn the Model 831 OFF.

“External Power Supply” on
page 2-8 for additional information
on the use of the hardware power
switch.
