4. Features
- Combining advanced electronic, singlechip and automatic measurement techniques in one instrument, with superior automatic functions and simple operation.
- All measured numerical values can be obtained by just one press on the key without any calculation. The instrument is adequate for continuous, fast and accurate measurements.
- Battery power supply has small size thus easy to carry, suitable for indoor and open-field use.
- With large screen and font. Can display measured values and auxiliary parameters at the same time, including resistivity, room temperature DC resistance at standard size, resistance, temperature, measuring current and temperature compensation coefficient.
- One instrument has multiple applications, and has two measurement interfaces: metal foil room resistivity measurement interface and DC resistance measurement interface.
- The functions of automatic constant current selection, automatic current reversal, automatic zero point correction and overcome the error caused by thermal voltage to line resistance and ensure the accuracy of each measurement.
▶ The instrument comes with the temperature sensor of the environment and the temperature coefficient of various materials, and the temperature is automatically compensated.
▶ Optional series of calibration resistor, with related software, to realize automatic calibration of the instrument.
- Special portable four-terminal measuring fixture is suitable for fast measurements of different foil and belt material.
The build-in data accumulator can record and save 1000 groups of measuring data and parameters. Connecting it to the host computer, the complete report can be generated.
