3.5.5.2 Setting of Equivalent Circuit
_CKT_
Press the _CKT_ key to display the equivalent circuit selection menu (see below), and select
parallel (suffix p) or series (suffix s) with a numeric key.

Equivalent CKT : Series Auto:OFF Current setting
0)Auto OFF 1)ON 2)Parallel 3)Series Options
Auto OFF Disables automatic selection of equivalent circuit.
ON Enables automatic selection of equivalent circuit.
Parallel Parallel equivalent circuit (automatic selection is disabled)
Series Series equivalent circuit (automatic selection is disabled)
If a setting is made or the EXIT operation is performed, the measurement screen comes back.
AUTO CKT lamp
The AUTO CKT lamp lights up when automatic selection of equivalent circuit is enabled.
When the primary parameter is L, C, R, Z, or Y, the equivalent circuit can be specified or its
automatic selection function can be used. However, |Z| and |Y| values do not depend on the
equivalent circuit.
If automatic selection of equivalent circuit is enabled, the equivalent circuit is automatically selected
based on the automatic selection rule listed below when the primary parameter is L, C, or R.
