2.3 AV38 Remote Display

For detailed information on configuration of AV38 current outputs, relays, host communications,
please refer to the AV38 manual. This manual will describe basic calibration, configuration and

dissolved oxygen compensation functions directly related to dissolved oxygen measurements

The AV38 is a universal display interface for DataStick sensor systems that includes dissolved oxygen

measurement. The enclosure has ¼ DIN dimensions for easy mounting and is rated NEMA 4X for

outdoor use. It uses a liquid crystal display (LCD) with a high contrast backlight for best readability and

is powered with 24 volts DC or optionally with line power (90 VAC to 240 VAC).

The AV38 automatically recognizes the type of DataStick connected to the
system and provides the appropriate calibration, configuration and diagnostic

menus. It has options for two 4-20 current outputs, two alarm/control/wash
relays and network communications to a host computer. In addition, the AV38

can address up to 247 DataStick sensors.
