A/C mode
If you set Input Mode to A/C, the digital input port is configured to detect the
presence of an A/C waveform. The next illustration shows how a digital input can
be used to monitor the operation of a fan.
You can use a digital input to synchronize the meter time to an IRIG-B time
source.
You can connect an IRIG-B time source to one of meter's digital inputs for IRIG-B
time synchronization; for improved accuracy use the digital inputs on the meter
base. For IRIG-B time synchronization, you must configure both the meter's digital
input and the meter's clock.
