TH0370 DC Characteristics Analyzer for Precision Resistors
暂无内容


Overview

Model TH0370, an analyzer to measure resistance and DC characteristics for precision resistors. The measuring range of 4-wire ohms is from 100 μΩ to 12 kΩ, the measuring range of 2-wire ohms is from 100 Ω to 1 GΩ. The optimal accuracy is up to ±3 ppm. The maximum output current is up to 100 A, the maximum voltage is up to 1000 V.

Applied to measure following parameters: TCR, thermal EMF, thermal stability time, power coefficient. In addition to this, it also can be used for following tests: short-time overload power, rated load long-term life, self-heating characteristic, thermocycling, thermo-shock, high temperature exposure, low temperature operation, resistance-to-humidity.

10.4-inch HD touch screen can display various measurement data and curves (waveforms), and makes operation convenient. Connect to a computer via RS-232, USB or IP interfaces, easy to build computer automatic test system.

Functions

● Resistance Measurement: Fast measurement by setting current (or voltage, power) and estimating resistance. The optional modes are high precision measurement and unidirectional fast measurement.


● Display: 8.5 digits

● TCR Measurement and Thermocycling Test: The high-low temperature test box is extra.

● Thermal EMF Measurement

● Thermal Stability Time Measurement

● Power (Voltage / Current) Coefficient Measurement

● Short-time Overload Power Test: E.g., 2.5x, 5x and 6.25x overload power test for 5 seconds. Power and time can be set freely based on your needs.

● Rated Load Long-term Life Test: Test time(e.g. 2,000 h and 10,000 h), switching time and testing power can be set freely based on your needs.

● Self-heating Characteristic Test: Automatically record the test curve when loading.

● Thermo-shock Test

● High Temperature Exposure Test

● Low Temperature Operation Test

● Resistance-to-humidity Test
