ANR96 - USER MANUAL
11.3)

GENERAL

The general menu is subdivided in the following sub menu:
• KCT, allows to set the current transforming ratio setting the primary and
secondary values of the CT, if it's used, in order to show the measured
values in primary terms. Primary Range: 1÷5000A; Secondary Range: 1
or 5A (for ANR96-1A is fixed to 1). I.e. Set KCT-Pri.=200 and KCT-Sec.=1
if a CT used is an 200/1 A.
• KVT, allows to set the voltage transforming ratio setting the primary and
secondary values of the VT, if it's used, in order to show the measured
values in primary terms. Primary Range: 1÷400000V; Secondary Range:
1÷750V. I.e. Set KVT-Pri.=20000 and KVT-Sec.=100 if a VT used is an
20000/100V.
• Mode, concerns the operation or measuring mode, it is possible to select
4 wires, 3 wires and Aron, following the connection mode as described on
chapter 6.4).
• Measure Time, is the filter time in the visualization measure. The range is
0÷50. The 0 value indicates none average on the measures, others
values indicates the average time (in seconds). If this value is very big
and the average powers storing is active, the values stored could be
wrong. It's better to set a value less than 5 seconds.
• Warnings, enables [Yes] or disables [No] the visualization every 15 second of the warnings page
alternatively at default page if current transformer connection is wrong or there is an inversion of the
phase sequence. The condition of battery low, it will appear independently of the set of this voice.
• B.Light, is the time (from 0 to 360 seconds) in which the display remains on, after the keyboard's
inactivity. To hold the display always on, it has to be set the value as 0. The brightness of display
declines about 10% every 1000 hour of work.
• Display, it's possible to choose between positive visualization (dark characters on clear
background) and negative visualization (clear characters on dark background).
• Def. Page Time, is the time of wait before to come back to default page. Range 10÷900 seconds.
• Synchronization, to set the fundamental frequency.
Mode: internal or external (V
Freq.: programmable frequency value (range 5÷500Hz).
• Set Clock, sets the internal clock of the instrument with relative date. The
format of the date is: dd:mm:yy and of the time is: hh:mm:ss
Day Light allow to set the yearly summer time change. It's possible to
enable the time shift of the summer time and the return at the solar time
at the fixed data. The instrument manages the summer time from the
1997 to the 2030.
• Password, it's possible to set a numeric password to modify the SETUP.
The default password is 0000: the setup can be always opened and it's always possible to change
any parameter. If the password is different by 0000 (from 0001 to 9999), at the entrance of setup,
the password will be request. if the password is ignored, it will be possible to see every parameter
but it will be impossible to modify it. Only with the correct password it's possible to change every
parameter. To set the new password as 0000, the instrument come back at default status. Call the
constructor to have an emergency password if you lose the password.
• Access, allows to input a code of 6 digits to enable the calculation and
the visualization of the harmonics and/or the time-bands and/or the load
control function. The code is showed on the test report associated to the
instrument and it can be requested to the manufacturer that needs to
know the serial number and the option/s to enable. In basic version of the
instrument no option is enabled, in a H type the Harmonics and
Timebands are enabled.
• User Page, select 5 parameters to visualize in the relative page.
• V Unbalance calculates the voltage unbalance between the line or phase.
