5.2.7 - Snapshot Function
During measurements, press the
key to block all measurements immediately – not only
those currently displayed. By doing so, the measurements will remain "frozen" on screen
until the same key is pressed again.
After blocking the measurements, all other menus can be scrolled through to check the
status of the other parameters captured at the same time.
The word STOP appears on the bottom bar to indicate that measurements have been
blocked.
NOTE
: blocking not only interrupts what appears on the display, but also the entire measurement process. This
means that the data during the block will not be recorded.
5.2.8 - EN50160 Menu
This menu allows the user to monitor certain main power quality parameters.
The first page displays the outcome of the EN50160 compliance test (Reference Standard
for power quality), according to the parameters selected in the Setup Menu (Sect. 4.2.10).
A test is performed to check whether frequency, voltage, harmonic voltage distortion, and
unbalance comply with the above-mentioned reference Standard and the nominal values
which have been set.
A table also shows the number of interruptions, dips and swells which have occurred during
the period monitored.
These pages display the last 5 interruptions recorded (if any occurred).
NOTE
: according to Standard EN50160, an "interruption" is defined as the simultaneous
drop of all phase voltages below 5% of nominal V (See Setup, Sect. 4.2.10). However, a
different threshold may be set by the user.
The Start Date and Time and Duration of each interruption are displayed.
When scrolling through the EN50160 Menu, the page of the most recent interruption is
displayed automatically.
To view any previous interruptions, scroll through the relevant pages using the
⊳
and
keys.
These pages display the last 5 dips recorded (if any occurred).
NOTE
: according to Standard EN50160, a "dip" is defined as a drop of one or more phase
voltages below 90% of nominal V (See Setup, Sect. 4.2.10). However, a different threshold
may be set by the user.
The Start Date and Time, Affected Phase(s), and Duration of each dip are displayed.
When scrolling through the EN50160 Menu, the page of the most recent dip is displayed
automatically.
To view any previous dips, scroll through the relevant pages using the
⊳
and keys.
