3. OPERATION

The Models 414D and 414B Batch Controllers use a low power CMOS

microprocessor to perform all control functions and calculations.

Both instruments are 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.
