Chapter 4, Test, Parameter, and Pass/Fail Limit Descriptions

Parameter 17, RX Tolerance for Setting Volume

This test parameter sets a tolerance window for the maximum percentage of error

allowed on the meter screen. The meter screen is displayed on the test set during

testing for manually setting the radio’s volume. The tolerance for setting volume

should be as accurate as the radio’s volume control will allow.

For Example:

If maximum audio power is 10 watts (set up in

Parameter 11, RX Maximum Audio

Power

) the meter screen on the test set will display a full-scale reading of 15 Watts

since the software scales the meter screen by 50%. The tolerance window

displayed on the meter screen will be a percentage of the 10 Watts. In this

example, test

Parameter 17, RX Tolerance for Setting Volume set to “10%” would

create a tolerance window of 1 Watt, “5%” would create a tolerance window of

0.5 Watts, and so forth.

The value should be based on the highest accuracy the radio volume control

allows. Enter a number equal to the accuracy you want and then run a test to see if

the radio’s volume control allows you to make the setting. If you cannot adjust the

volume within the tolerance window, enter a larger number. The value is entered

in % error.
