I) Inspection
a) Your 6308DT MICROCOMPUTER BASED DO/ TEMPERATURE
CONTROLLER unit was carefully inspected and certified by our Quality
Assurance Team before shipping. If any damage has occurred during shipping,
please notify Global Water Instrumentation, Inc. and file a claim with the carrier
involved.
I) General Introduction
a) The Global Water Model 6308DT (DO and Temperature) System, is a rugged
microprocessor based instrument assembled in a watertight ¼ DIN case, designed
for use in laboratories and process control applications.
The model 6308DT microprocessor allows the user to easily recalibrate the
parameters for the probes. The DO system requires only a single calibration,
regardless of which dissolved oxygen display you use. The microprocessor also
performs a self-diagnostic routine every time you turn on the unit providing you
with basic information about the stability of the instrument.
The system simultaneously displays DO, Temperature, Relay status, and current
output in one LCD graphic screen. The LCD also includes a backlight for badly lit
environments. This system uses a "polygraphic clark" membrane for the DO and a
precise thermistor for temperature, providing you with accurate readings for all
your measurements.
The model 6308DT is equipped with 5 relays (2 active Low and 2 active High
relays for DO and one programmable high or low relay for temperature); all
relays are hysteresis driven and configurable to CENTER or EDGE mode. The
system also has an isolated 4-20mA analog output, offset and span configurable
for the DO display.
The model 6308DT comes with a RS485 interface that can easily let the user log
all data (from multiple models 6308 or 6309) with an IBM© PC/AT compatible
computer.
II) Mounting Procedure
a) Make a cutout on any panel, with a thickness of 1/16 in. (1.5 mm) to 3/8 in.
(9.5mm).
b) Remove the mounting assembly from the controller and insert the controller into
the cutout.
c) Replace the mounting bracket assembly onto the controller and secure the
controller to the mounting panel.
