- Provides ten electrically isolated analog input channels for measuring voltage and temperature, plus four pulse-counting input channels. The isolated inputs alleviate constraints when measuring temperatures in live electrical circuits while minimizing interchannel interference
- 10 ms scanning of all channels provides rapid sampling capabilities To meet the demand for measuring sudden changes in load, this model tracks waveforms that earlier 100 ms models could not
- CompactFlash card makes direct recording a snap. For long-term data recording, transfer data to a PC via USB connection
- Widescreen, bright LCD gives excellent viewability. The beautiful, wide QVGA-TFT display is ideal for waveform monitoring
