Accuzact AZ-DAQ-USB 16-Bit Data Logger is an easy-to-use, low-cost, low-speed USB data acquisition system designed for DC voltage measurement, sensor testing, battery testing, and long-term voltage data logging. The unit provides 1 to 4 analog input channels and supports either single-ended or differential input configurations. It measures DC signals in the 0 to +5V or -5V to +5V ranges, with up to 16-bit resolution and enhanced resolution when using the software gain setting. Simply connect the data logger to a compatible Windows PC or laptop through USB. No external power supply is required and the device uses USB HID Plug-and-Play technology, eliminating the need for a separate hardware driver.

- Monitoring low-level DC signals
Important Limitations & Buyer Notice:
- This is a low-speed USB HID data logger, not a high-speed oscilloscope or high-speed DAQ system.
- USB HID polling is less than 125 Hz for single-channel operation.
- When using multiple channels, changing the polling interval during HID interrupt transfers may cause delays or skipped/lost channel data.
- The analog input can display a floating/unconnected voltage when no signal source is connected.
- For a ground-level reading, connect the analog input (+) to GND/(-), connect the test leads, or connect the input to a known signal source.
- To avoid inaccurate floating-input readings, connect a signal source before pressing the Start Record button.
- Because the system records data to the computer's hard drive in real time, multiple Accuzact AZ-DAQ-USB modules should not be connected to the same computer simultaneously. This includes other Accuzact USB data acquisition modules such as current, voltage, or wireless DAQ systems.
- Please Verify Compatibility Before Purchase
- This device is intended for low-speed DC voltage data acquisition and logging.
