To turn the instrument on:
15) Press the switch <ON> at the analyzer frontal cover. The analyzer introduction
screen appears. The user can now select the operation mode program for the
analyzer
16) After some seconds, a screen allowing the choice of the analyzer program to be
used is shown up.
17) One the desired program has been selected, analyzer will check the type of
ammeter clamps connected to the analyzer. This process is only performed
when analyzer is turn on, and in case that the connected clamps does not
matches with the programmed ones, then the analyzer will automatically give the
option to change the ammeter clamp setting:
- Press <ENTER> to validate the suggested clamp setting. The new
transformation ratio will be set at the ratio detected in the clamp L1.
- Press <ESC> to exit the auto-checking process with no change in
the analyzer setup.
18) After some seconds the principal electrical parameters of the network are
displayed.
NOTE : If nothing is shown on display, a discharged battery or any problem
with the display contrast might exist.
Initial considerations after the analyzer start-up:
- Format the memory if necessary (see section 6.4.-FILES Menu).
- Clear maximum & minimum values as well as energy counters if necessary
(see section 6.5.- CLEAR menu: Deleting data).
- Open a file with the desired name (see section 6.1.2.3.- NAME: recording file
name). All data will be automatically saved in this file until a new one is
opened. The analyzer internal memory can contain several files (different
analysis).
Warning :
Take into account that when the memory is formatted all previously stored
data is lost. When opening a new file (a different name that the previous one) the
internal memory is not deleted.
When starting new measurements at any installation the meter
programming must be checked and modified if necessary (following steps attached
at Section 6.- PROGRAMMING THE ANALYZER) Otherwise, the analyzer will work
according the last used program (this is saved in memory even after powering the
meter off).
Points to be mainly checked would be:
- Ratio of Current clamps (see section 6.1.1.2.-)
- Voltage transformer ratio (see section 6.1.1.2.-)
- Recording period (see section 6.1.2.1.-)
