VOLTpoint Features
Figure 2
The key features of VOLTpoint (DT9873) instruments are as follows:
• Direct connection of analog input channels for differential voltage inputs; removable
• One 24-bit, Delta-Sigma A/D converter per channel for simultaneous, high-resolution
• Software-selectable input range of ±10 V or ±60 V per channel (note that for the ±60 V
• Throughput rate of up to 10 Samples/s for all channels
• Software or external, digital trigger on digital input line 0 starts acquisition
• Auto-calibrating front-end resets the zero point on each power-up; in addition, the
• Measurement Calibration Utility allows you to calibrate the instrument in the field (see
• 8 opto-isolated digital input lines; you can read the digital input port through the analog
• 8 opto-isolated digital output lines; the outputs are solid-state relays that operate from
