Alarm Limits
You can control the slope of the pulse from the alarm outputs
(the selected configuration is used for all four outputs). In the
falling edge mode, 0V ( TTL low) indicates an alarm. In the rising edge
mode, +5V ( TTL high ) indicates an alarm. A Factory Reset (*RST
command) will reset the slope to falling edge.
