Recommended Calibration Procedure

e CP 52 is a very versatile instrument. While this allows it to conform to the requirements of a large number of system applica-

tions, it also results in complexity. For this reason, it is very important to use an organized approach to system calibration. Once the

system is connected and the internal switches set for your speciﬁc application, it is important to take the time for proper calibration.

e following is an ordered list of system adjustments that makes calibration easy and results in optimum performance.

is procedure assumes that a microphone is used for the Page. e procedure (except for the exact wording) is the same for other

Page sources.

Make sure the POWER is oﬀ!
