10.9 2-Pole Measurement with Rapid or Semiautomatic Polarity
Reversal
Rapid, semiautomatic polarity reversal is possible for the following
measurements:
• Voltage U
• Loop impedance Z
LP-E
• Internal line resistance Z
L-N
• Insulation resistance R
INS
Rapid 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
N
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 after sav-
ing.
Polarity variants can be skipped by pressing the I
N
key at the
instrument or the test plug.
