Sequential control fault analysis
Momentary supply dropouts and low AC voltage are often found to
be causes of abnormal interruptions and warnings from sequentially
controlled devices in factory production and testing lines. For optimal
operational analysis, specify
an abnormal power event as
a trigger and simultaneously
record waveforms of associated
sequential relay signals, AC
power and DC voltage systems.
CB timing measurements
Analyze the relationships of multi-point logic signals and analog
waveforms to detect timing issues that can affect power supply
circuit breakers. Use logic probes to record relay operations on up
to four channels, or use Differential Probe
9322 for 440-volt power measurements
and for support of CAT III and CAT IV
overvoltage measurement
categories.
When facility troubles require waveforms right away!
Battery operation is especially convenient in those situations where
no power outlet is available. Just plug in the supplied AC adapter
to recharge the battery, regardless of whether the HiCORDER is
on or off. The battery pack is automatically quick charged (auto-
recharging function) whenever its capacity is depleted. A full
charge provides about two hours of operation.
Synchronize two HiCORDERs together for four-channel recording!
For those times when two channels are just not enough,
synchronize two 8870-20's using the external trigger I/O terminals
(apply the trigger output from one to the external trigger input of
the other). Then use synchronous start
to automatically record four channels of
measurement data to a CF card.
