II. GENERAL INTRODUCTION
The Jenco Model 6308CT (
C
onductivity and
T
emperature) 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 6308CT microprocessor allows the user to easily
recalibrate the parameters for the probes. The Conductivity system
requires only a single calibration. 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 Conductivity, Temperature,
cell constant or TDS factor, relay status and mA output in one LCD
graphic screen. This system uses a two-wire or four-wire type
sensor for the conductivity and a precise thermistor for
temperature, providing you with accurate readings for all your
measurements.
The model 6308CT is equipped with
three relays: two
programmable High/Low control relays for conductivity/TDS and
one programmable High/Low control 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 Conductivity/TDS display.
The model 6308CT comes with a
RS485
interface which can easily
let the user log all data (from multiple model 6308 or 6309) with
an IBM
©
PC/AT compatible computer. For advanced users, the
model 6308CT may also be remotely controlled from main display
mode to all calibration/setting modes.
