Ringers

This function measures the capacitance associated with one or more ringer circuits on the line or the equivalent number of ringers (1 ringer = 0.47 uF).

Either the Ringers Capacitance screen or the Ringers (equivalent) screen will be displayed depending on which was last selected. During the measurement an hour glass will be visible at the bottom of the display.

When the measurement is complete, the Ring- Ground, Tip-Ring and Tip-Ground capacitance will be displayed. To display the equivalent ringer count, press the [Tab] key.

Pressing the [Tab] key again will return the screen to Ringers Capacitance. Press the [Enter] key to repeat the test.
