replacement is required.
Refer to §. 3.2.2.

3.4.10. Parallel / Series Mode

The IX 3131B is capable of displaying Parallel and Series mode data for all ranges.
The parallel mode is default for Capacitance and Resistance measurements and the
series mode is default for Inductance measurement.
However, each data can be transformed to the other mode reading in the following
step. To get parallel mode data under the Inductance measurement, press the
« L / C / R » key for one second to enter the « SER » and « PAL » mode.
Following tables are shown which range is specified for application mode.
The " √ " means the ranges may use for Parallel and Series modes.
For " ◊ " means, the accuracy of ranges is specified for default measuring mode.
