• 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
instrument supports anytime calibration, performing an auto-calibration function on
software command
• Measurement Calibration Utility allows you to calibrate the instrument in the field (see
page 18
for more information on this utility)
• 8 opto-isolated digital input lines; you can read the digital input port through the analog
input data stream for correlating analog and digital measurements
• 8 opto-isolated digital output lines; the outputs are solid-state relays that operate from ±30
V at currents up to 400 mA (peak) AC or DC
VOLTpoint Features
The key features of VOLTpoint (DT9873) instruments are as follows:
• Direct connection of analog input channels for differential voltage inputs; removable
screw terminal blocks for each channel for quick wiring
• One 24-bit, Delta-Sigma A/D converter per channel for simultaneous, high-resolution
measurements
• ±500 V galvanic isolation channel-to-channel and to the host computer to protect signal
integrity
• Software-selectable input range of ±10 V, ±100 V, or ±400 V per channel
• Throughput rate of up to 10 Samples/s for all channels
• Software or external, digital trigger on digital input line 0 starts acquisition
