3.1 Overview
This module provides information for specifying PRM2103 heater controls,
viewing data, performing calibration checks, and upgrading firmware
through the SoundAdvisor Model 831C and G4 LD Utility.
3.2 Performing the Acoustic Calibration
To perform an acoustic calibration, follow these steps:
Step 1
Remove the birdspike and windscreen if the EPS2116
environmental protection system is installed.
CAUTION
Do not remove the
microphone or the
microphone grid cap.
Step 2
Place the calibrator, like the CAL250 or CAL200, over the
microphone. Apply the calibrator slowly to avoid applying a
sudden large pressure change to the diaphragm.
