4. Use the and keys to choose from the following values: KILO (for kWh / kvarh), X
1 (for Wh / varh), MEGA (for MWh / Mvarh).
5. Press the key to confirm your selection.
 "SET" is displayed. The device goes to the next parameter "Lmt".
6. Press the key.
 The display shows "Lmt" at the top and "ON" in the middle row. In addition "1 %" is
displayed on the bottom left.
7. Press the or keys to switch between "ON" and "OFF".
 If Lmt is active, "1 %" appears on the bottom left of the display. The function is
used to activate measurement signal suppression to suppress incorrect
measurements caused by noise on the measuring cables. This can be required if
the measuring cables - particularly the cables between the multifunction electrical
energy meter and the external current transformers are not shielded and/or are
routed in the immediate vicinity of the primary circuits. The 1% limit always
refers to the full scale value of the power measurement, which results from the
maximum input voltage and the set transformer primary current, while taking the
interlinkage factor into consideration if necessary. If the function is switched on,
"1 %" also appears on the bottom left of the display in the display mode.
8. Press the key to confirm your selection.
"SET" is displayed. The device returns to the first menu level.
6.3.9 Self-test – TEST
This screen contains several functions for performing self-tests on the multifunction
electrical energy meter.
1. Call up the Setup menu.
2. Press the or keys until TEST is displayed.
3. Press the key.
4. Use the and keys to choose from the following values: diSP ON (when selected
by pressing the key, all the segments of the LCD display are switched on to allow
users to detect a segment failure); diSP TOGL (when selected by pressing the key,
the display alternates between two different display modes. This helps the user
identify whether individual segments do not switch off); PHAS SEQ (when selected by
pressing the key, this function checks whether the voltage and current connections
have been established correctly on the energy meter. PSEQ (phase sequence), V 123, I
123 is displayed if all the connections are correct. If PSEQ, V 132, I 123, for example,
is displayed, this indicates that a voltage connection is faulty. If PSEQ, V 12_, I 123,
for example, is displayed, this indicates that a voltage connection is missing.
6.3.10 Displaying the software version – SOFT
This function directly displays the version of the internal software (firmware).
1. Call up the Setup menu.
2. Press the or keys until SOFT is displayed.
3. Press the key.
