3. OPERATION

The Model 414A Batch Controller uses a low power CMOS microprocessor to

perform all control functions and calculations.

The instrument is fully programmable with all operating parameters and

calculation constants user programmable. (See Section 5 entitled "Calibration"

for information on programming.) All parameters and constants are stored in a

non-volatile memory which retains data without battery backup for a minimum

of 10 years.

A block diagram of the instrument is shown below.
