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