Averaging

Moving average, 1 to 16 samples, software-selectable

Calibration

Calibration is performed with each channel scan to remove offset and gain error.

CJC channel is also measured with each calibration.

Processor reset

On power-up, watchdog timeout, or software command. Processor boots within one

second of reset. Active low.

Watchdog timer

1.6 seconds nominal. Processor generates watchdog disable signal after boot-up.

Temperature units

Programmable for conversion to C or F

Interrupts

2, 3, 4, 5, 6, or 7

Interrupt enable

Programmable

Interrupt sources

Dual port RAM when the processor mailbox has data.

Crystal Oscillator

Configuration

CJC centered in an isothermal block on which the screw terminals have been

mounted.

Channels

16 (plus CJC output)
