The analyzer uses the number you enter in [
CAL VALUE AT MKR
] to calculate a new
value for [
XDCR SENSITVTY
]. This new value is the calibration factor that ensures the
accuracy of your microphone measurements. The analyzer automatically stores this
value and the [
XDCR UNIT LABEL
] value in nonvolatile memory, so they will not be
lost at preset or power-down. However, the values will be used only when
[
XDCR UNIT ON OFF
] is set to ON.
