The LR8431-20 delivers improved thermocouple measurement accuracy and reference junction compensation accuracy. Evaluating motors and inverters used in electric and hybrid vehicles The LR8431-20 enables stable, low-noise measurement of high-speed, high-resistance targets. Efficiency measurement and performance evaluation of air conditioning equipment The LR8431-20 supports simultaneous, multi-point measurement, for example of input and output at multiple air conditioning registers or the temperature of internal components. Temperature measurement and performance evaluation of internal components in electronic equipment Used with a wind velocity converter, the LR8431-20 can measure cooling ef?ciency inside equipment enclosures. This compact logger excels in a broad range of settings, from production lines to research and development. Ten Isolated Analog Input Channels There's no need to worry about differing potentials of measurement objects when measuring temperature and voltage. All ten analog channels are isolated. Even when measuring temperature and voltage at the same time, interchannel interference and electric shock hazards are eliminated. The four pulse channels are ideal for counting revolution pulses to measure rotation speed. High-Speed Sampling 10 ms Sampling and Recording Across All Channels Abrupt changes in load need to be measured during development of EV • HV • PHV, for which multi-channel, 10 ms sampling is essential. This HiLOGGER can track waveforms that could not be followed with the 100 ms sampling interval previously available. Enhanced Noise Suppression Noise-resistant measurement circuitry for improved readings Measurement involves the deployment of a delta-sigma type A/D converter. Suppress inverter switching noise and line-frequency hum by digital ? ltering with the HiLOGGER's proprietary oversampling technology
