II. GENERAL INTRODUCTION
The Jenco Model 6309 POT ( p H, O RP 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 6309 POT microprocessor performs a self-diagnostic
routine every time you turn on the unit providing you with basic
information on the stability of the instrument.
The system simultaneously displays pH, ORP, Temperature, relay
status and current output in one LCD graphic screen.
The model 6309 POT is equipped with 5 relays (2 programmable
high or low relay for pH, 2 programmable high or low relay for ORP
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 a isolated 4-20mA analog output, offset and
span configurable for the pH or ORP display.
The model 6309 POT comes with a RS485 interface that 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
6309 POT may also be remotely controlled from main display mode
to all calibration/setting modes.
