Bits 00-01

Missing pulse multiplier bits (channel 1) – used to modify the Minimum Frequency Sampling Time to allow the frequency
bandwidth to be more closely adjusted to the value needed to report the proper frequency and report a missing pulse
more quickly.

Default

= no multiplier; alarm generated immediately

Bits 02-04

Number of pulses to terminate sampling (channel 1) – Lets you calculate Frequency when a specified number of input
pulses have occurred. This allows earlier reporting of the frequency than the Minimum Frequency Sampling Time, when
many input pulses are occurring. Accurate frequency determination is possible without waiting for the full Minimum
Frequency Sampling Time to expire.

Defaul

t = minimum frequency sampling time.
