Identification and Overview
BAPI's ZPM is designed for quick
and easy field installation. The
outputs, ranges, units, directionality,
are all easily set in the field without
powering the unit.
The optional LCD display helps with
troubleshooting because it displays
the actual pressure regardless
of the selected pressure range.
Three LEDs on the face of the unit
indicate when the pressure is "Out
of Range Low", "In Range" or "Out
of Range High" for the selected
range. The appropriate LED will
flash when out of range.
Switch Setup - Outputs, Ranges, Units/Response
NOTE! Always follow the Auto-Zero procedure after changing settings.
