Bit 184:215 – Switch SW3 high threshold
This field contains switch SW3 high threshold in nA units.
Bit 216:247 – Keepalive interval
This field contains keepalive time interval in ms units. When keepalive interval is different from 0
ms the power supply expects to be polled within a period not greater than keepalive interval by
whom last sent to it the enable command, otherwise it stops and sets communication alarm latch.
Keepalive timer resets after any successfully processed command. Keepalive interval cannot be
lower than 1000 ms, the only exception is 0 ms which disables keepalive timer.

This field contains the conversion rate in A/Torr units useful to compute chamber pressure from
output current.
