5.7 Freely Selectable Parameter Settings or Limit Values
In addition to fixed values, other values can be freely selected
within predefined limits for certain parameters, if the symbol for
the EDIT menu (3) appears at the end of the list of setting values.
Freely Selecting a Limit Value or Nominal Voltage
1 Open the submenu for setting the desired parameter (no figure, see section
5.6).
2 Select parameter (U
L
) using the ↑ or ↓ scroll key (no figure, see section
5.6).
3 Select a setting value with the help of the icon and the ↑ or ↓ scroll
key.
4 Select the edit menu: Press the key with the icon.
5 Select the desired value or unit of measure with the LEFT or RIGHT scroll
key. The value or unit of measure is accepted by pressing the ↵ key. The
entire value is acknowledged by selecting
✓ and then pressing the ↵ key.
The new limit value or nominal value is added to the list.
Note
Observe predefined limits for the new setting value.
New, freely selected limit values or nominal values
included in the parameters list can be deleted/edited at
the PC with the help of ETC software.
When the upper limit value is exceeded, this value is
accepted (in the example: 65 V), when the limit value is
fallen short of, the predefined lower limit value (25 V) is
accepted.
5.8 2-Pole Measurement with Fast or Semiautomatic Polarity
Reversal
Fast, semiautomatic polarity reversal is possible for the following
measurements:
• Voltage U
• Loop impedance Z
LP-E
• Internal line resistance measurement Z
L-N
• Insulation resistance, R
INS
Fast Polarity Reversal at the Test Plug
The polarity parameter is set to AUTO.
Fast and convenient switching amongst all polarity variants, or
switching to the parameter settings submenu, is possible by
pressing the I
ΔN
key at the instrument or the test plug.
Semiautomatic Polarity Reversal in Memory Mode
The polarity parameter is set to AUTO.
If testing is to be conducted with all polarity variants, automatic
polarity changing takes place after each measurement when the
“Save” button is pressed.
Polarity variants can be skipped by pressing the I
ΔN
key at the
instrument or the test plug.
