Setting Measurement Conditions (basic settings)
DC adjustment (reducing measurement error) (DC)
Enabling the DC adjustment function causes the instrument to set the generated voltage to 0 V and
acquire the offset value generated by its internal circuitry in order to reduce measurement error.
(Default setting: ON)
Disabling the DC adjustment function allows high-speed DC resistance measurement since the
offset value is not acquired before each measurement is performed.

•Disabling DC adjustment may cause the measurement error to increase.
• When using the instrument with DC adjustment disabled, acquire the adjustment value with the sample (or
a circuit with equivalent DC resistance [Rdc]) connected.
• Because the adjustment value will vary when the sample’s Rdc or ambient temperature changes, disabling
DC adjustment will prevent accurate measurement.
