Appendix K: C-Series Analog Adapter
Introduction
The C-Series Analog Adapter (P/N 2300-480) allows users to convert the standard
digital output from the C3 Submersible Fluorometer to a 0 - 5 VDC analog signal.
The Adapter can convert the signal from 1, 2, or 3 channels installed on a C3. The
voltage output is proportional to the fluorescence intensity measured by the sensors.
Modeled after the C3 Submersible Fluorometer’s battery pack, the Analog Adapter
is designed to connect directly to the C3. The C3 Battery Bracket (P/N 2300-603) is
required to hold the Analog Adapter in place and secure it, preventing any break in
communication or power. With the C-Series Analog Adapter users can integrate
their C3 Submersible Fluorometers into any CTD or multi-parameter platform that
will accept a 0 – 5 volt output signal.
Required Accessories
The following accessories are required for installation and operation of the Analog
Adapter.
Battery Bracket (PN:2300-603) – Designed to hold the Analog Adapter in place and
support it to avoid any break in communication or power ensuring continuous data
output.
An Analog (Pigtail) Cable – We offer various lengths that are necessary for standard
integrations.
- P/N: 2100-750 2 foot pigtail cable
- P/N: 2100-755 5 meter pigtail cable
- P/N: 2100-751 10 meter pigtail cable
- P/N: 2100-752 25 meter pigtail cable
- P/N: 2100-753 50 meter pigtail cable
C3 Submersible Fluorometer Setup
There are only a few steps required to set up the C3 Submersible Fluorometer for
analog output. There are two methods that may be used for calibrating C3
channels/sensors. The first is a Raw Fluorescence Units Blanked Calibration (refer
to section 3.3.2 in the C3’s user manual) and the second is a Direct Concentration
Calibration (refer to section 3.3.1 in the C3’s user manual). Use the Raw
Fluorescence Units Blanked (RFUB) calibration if you do not have a standard with
known concentration or if you are unsure what numeric value to assign your
standard.
NOTE: Repeat either one of the above calibrations for each channel that will
be used for Analog Output.
