Open Collector Outputs (OUTPUT)
The meter is equipped with two NPN open collector outputs that may be set up for
pulse outputs, alarms, timed pulses, or turned off.
Pulse outputs are based on K-factor, total or grand total counts, or one-for-one
retransmit for input pulses. Both outputs may be used to generate a quadrature
output based on any pulse menu output type. An output test mode is also selectable
to generate pulses at a constant programmable frequency.
Alarms are available based on the rate, total, or grand total. The alarm status will
show on the display even if the output is not wired. The outputs may also be forced
on or off.
A timed pulse output generates constant pulses at a specified frequency and on
time.
A total reset output generates a pulse whenever the selected total is reset, total or
grand total, regardless of the reset method used. The On time is programmable
between 0.10 and 99,999.99 sec.
The output may be disabled by selecting Off.
