Event List
|
Dips, swells and
interruptions are detected and stored in the
event list. Also any trigger which fires
generates an event added to this list.
The Event list shows the exact time when the
event occurred as well as the duration and
magnitude. Sorting by several attributes of
these events is possible to select one for
further root cause analysis.
RMS values, transients and fast transients can
be stored if a trigger fires. |

In case of a
power supply failure an internal battery
|
| |
maintains
the supply for up to 40 minutes.
Afterwards, or |
| |
in case of
discharged accumulators the Fluke 1760
is turned |
| |
off and
continues the measurement with the
latest settings |
| |
as soon as
the supply voltage returns. the battery
can be |

replaced by
the user. |

Input Filter
|
Each channel is equipped with a passive
low-pass filter, an anti-aliasing filter and a
16-bit A/D converter. All channels are sampled
synchronously with a common quartz-controlled
clock pulse.
The filters protect against voltage transients
and limit the signal rise, reduce high
frequency components and especially the noise
voltage above half the sampling rate of the
A/D converter by 80dB, thus achieving very
small measuring errors in an exceptionally
large amplitude range. This is also valid
under extreme operating conditions like
transient voltages at the output of
converters. |
