4-28 General Operation
1403-IN001A-US-P
Oscillography (1403-MM only)
The Powermonitor II provides two types of
oscillography. Both are triggered simultaneously and
sampled at 10.8 kilo-hertz. The types are:
•
Simultaneous 7-channel 2-cycle oscillogram
•
User configurable simultaneous 2-channel 12-
cycle oscillogram with up to eight cycles of
pretrigger data
These oscillograms can be triggered manually or as
the result of a setpoint. Oscillogram configuration
and retrieval can only be accomplished through the
Smart Communication Card.
Oscillography has two modes of operation:
•
Hold
•
Overwrite
Hold fills a buffer when an oscillograph is triggered,
and it does not allow another oscillograph to trigger
until the Master Module is commanded to cancel the
hold. Overwrite allows oscillographs to be
overwritten when multiple triggers occur.
The pretrigger data of the 2-channel simultaneous
12-cycle oscillogram is disabled by setting the
number of pretrigger cycles to a -1. This action
makes the real time metering update slightly faster.
Self-test/Diagnostic Information
The Powermonitor II and its accessories have an
extensive array of internal self-tests. Complete self-
tests are executed at device powerup, and critical
tests are continuously run during operation of the
device. The results of these self-tests are used to
insure the integrity of the information provided by
Powermonitor II and its accessories. Improper self-
test results cause the device to cease normal
operation.
Bulletin Number
For the Powermonitor II, this parameter returns 1403.
Master Module Firmware Revision Number
This parameter returns the firmware revision number
of the Master Module. This value is returned through
the Smart Communication Card as an integer such
that 1.00 is represented as 100.
