Resistance
This function measures the following resistances.
Range Measurement Range Notes
400Ω 0.00 Ω ~ 440.00 Ω
Voltage applied current measurement method
Typical values: 1 mA@0 Ω, 781 μA@400 Ω, 240 μA@4 kΩ
4000Ω 0.0 Ω ~ 4400.0 Ω
Wiring Systems
The following wiring systems are available: two-wire, three-wire, and four-wire.
Two-wire system: Because measurements include the resistance of measurement lead
cables and contact resistance, errors become large. Use this when the
resistance of the DUT is sufficiently larger then the resistance of the
measurement lead cables and contact resistance.
Three-wire system: By making the length of the three measurement lead cables the same,
measurements can be made without hardly being affected by the
resistance of the lead cables.
Four-wire system: Measurements can be made by eliminating the resistance of measurement
lead cables and contact resistance. Use this when you want to make
accurate measurements.
Temperature Measurement Using Thermocouples
Temperature is measured using the following thermocouples.
