PCURrent and SEARch time for pulse high measurement
NOTE
If a pulse is not present, timeout needs to elapse (TOUT). This (TOUT elapsing)
paces the unit for processing bus commands.
• If DETECT ON (only), search time needs to elapse before responding to a
bus command
.
• If SEARCH OFF or FAST ON, search time and TOUT are not incurred
while processing non-user triggered commands (refer to
Section 9
of the
User’s Manual for examples of user triggered).
• Search time or TimeOUT needs to elapse when checking TLEV command
for valid setting, if enabled.

TOUT setting must account for Search Time and Period.
P
=Search for Pulse High edge started
R
=Reading time taken
D
=Detected pulse edge (Rising for pulse high
and average measurements)
Search Time:
Measured from when unit starts looking for the
pulse until the first detectable desired edge. This
is a rising edge for HIGH and AVG measurements,
and falling edge for LOW measurements.
Period: Time between consecutive pulse edges.
