4.4 Source Resistance (Ω) Signals

4.4 SourceResistance(Ω)Signals

Procedure for Generating Resistance Signals

• The instrument generates a resistance signal by receiving the resistance-measuring current I supplied from the device under calibration (resistance meter, RTD thermometer, etc.) and delivering the voltage V = R × I proportional to the preset resistance R between the output terminals, and thus producing the equivalent resistance R = V/I.

Consequently, the instrument generates the signal correctly only for

such devices that employ this method of measurement.

• The allowable range of the resistance measuring current I that the instrument receives from a resistance measuring device under calibration is rated as 0.01 to 5 mA.

(This varies depending on the generated resistance value. For details,

refer to the specications.)

Obtaining Accurate Measurements

• Since the generated resistance value is calibrated without including the voltage drop component of the lead cables, the resistance

(approximately 0.1 Ω on a round-trip basis) of the lead cables becomes

an error in the case of a load current.

• For accurate generation of resistance signals, use a three-wire connection

for output. (Refer to the gure below.)

• If the capacitance between the terminals of a device under calibration is greater than 0.01 µF, the instrument may be unable to generate correct resistance values.
