8-2-2 Setting for Measurement Method
Measurement method is selectable from: 2-wire (2-wire system), 3-wire
(3-wire system),4-wire (4-wire system) and ρ (earth resistivity).
Select Wire with the Cursor Key on the CONFIG̲SETTING Screen and
press the
Key to proceed to the Wiring Setting Screen. (Fig.9)
Select the appropriate Wiring System with the Cursor Key and press the
Key. Then the CONFIG̲SETTING Screen with the selected Wiring
System will be displayed .
8-2-3 Setting for Measurement Frequency
Measurement signal frequencies can be selected from following four
frequency bands with this instrument in order to minimize the influence of
the series interference voltage (earth voltage).
*Auto *94Hz *105Hz *111Hz *128Hz
The instrument automatically select the best suitable frequency when
selecting Auto and output the frequency signal. Select Freq with the
Cursor Key on the CONFIG̲SETTING Screen and press the
Key to
display the Frequency Setting Screen (Fig.11).
