System Circuit Description
All subsystems in the instrument are microprocessor (CPU) controlled.
Each input module contains an A/D converter that connects to the instrument
through an isolation device. (The isolation devices are in the input modules.)
In addition, separate power supplies are provided for each channel, electrically
isolating them from the instrument.
After processing by the CPU, measurement data is stored in memory for display
on the LCD or output to the printer. Data can be saved to and reloaded from a
PC Card or other external storage media.
