Connecting Sensors; Connecting To An Em50 Series Logger - Decagon Devices VP-3 Operator's Manual

5 CONNECTING SENSORS

VP-3
5 Connecting Sensors
The VP-3 sensor was designed to work most efficiently with Decagons
Em50, Em50R, Em50G data loggers, or the ProCheck handheld
reader. The standard sensor (with 3.5 mm stereo connector) quickly
connects to and is easily configured within a Decagon logger or
ProCheck.
The VP-3 sensor incorporates several features that also make it an
excellent sensor for use with third party loggers. The sensor may be
purchased with stripped and tinned wires (pigtail) for terminal con-
nections. Visit our website at www.decagon.com/support/literature
to get extensive directions on how to integrate the VP-3 sensor into
third party loggers.
The VP-3 sensor comes standard with a five meter cable. Sensors
may be purchased with custom cable lengths for an additional fee
(on a per-meter fee basis). Decagon has tested its digital sensor suc-
cessfully up to 1,000 meters (3,200 ft). This option eliminates the
need for splicing the cable (a possible failure point).

Connecting to an Em50 Series Logger

We designed the VP-3 to work specifically with the Em50 data logger.
Simply plug the 3.5 mm "stereo plug" connector directly into one of
the five sensor ports.

The next step is to configure your logger port for the VP-3 and set
the measurement interval, this may be done using either ECH2O
