1. In the parameter menu, press [
↓] or [↑] to select a parameter (the cursor moves
two rows at a time)
2. When the appropriate parameter is highlighted, press [E] for 2 seconds
3. Enter the password (see Figure 4.2.-1) and press [E]
(the password is only required for the first parameter setting and will apply as
long as the user stays at technical level or the backlight time-out elapses)
4. Set the parameter
• In case of an enumerator (the entire text is blinking), press [
↓] or [↑] to scroll
for the desired item
• In case of a numeric value or a character string (the first digit/character is
blinking):
I Press [
→] or [←] to select a digit/character
II Press [
↓] or [↑] to scroll for the desired digit/character
III Repeat I and II to define other digits/characters
5. Press [E] to confirm the new setting or [C] to restore the previous setting
• When a parameter change is confirmed with [E], the new setting takes effect
immediately. However, all parameter changes need to be saved in the non-
volatile memory as described in section “Saving parameters” on page 23.
• If an illegal setting value is confirmed, a message in the assisting window tells
the user that the setting is out of range, and the previous parameter value
remains unchanged.
Note! The special parameters for measuring devices in MAIN MENU/
Configuration/Current trafo, .../Rogow.sensor,
.../Voltage trafo and .../Volt. divider become valid only
after they have been stored via the parameter “Store” and the terminal has
been reset via the parameter “Software reset” in MAIN MENU/
Configuration/General.
