3.3.1 Manually modifying the Calibration Parameters
Use the Tools → Transducer Swap-out utility in MeterLink to easily update
parameters such as path lengths, delay times, and delta times for chord. This
is necessary anytime housings have to be replaced for a chord or if the meter has
performed a cold start. The wizard steps you through selecting which chords have
been changed, which components in the chords have been changed, as well as
recalculating new path lengths based on the information entered. This utility is
only available while connected to a meter. The length of the meter body is found
on the original calibration sheet supplied with the meter.

Swap-out Wizard. The Transducer Swap-Out Wizard is a utility that allows
you to easily update parameters such as path lengths, delay times, and
delta times for chord. This is necessary anytime housings have to be
replaced for a chord. The wizard guides you through updating which chords
have been changed, which components in the chords have been changed,
as well as recalculating new path lengths based on the information entered.
This utility is only available while connected to a meter. Collect and
save a Maintenance Log and verify the meter is optimally performing. If
