The Datron 1071D is a high-precision digital multimeter engineered for calibration laboratories and demanding metrology applications. This AUTOCAL-series instrument delivers 6½–7½ digit resolution with floating-point display, spanning DC voltage, AC voltage, resistance, DC current, AC current, and ratio measurements from a single platform. The 1071D employs Datron’s proprietary Log Feedback true RMS technique for AC measurements, ensuring speed, wide dynamic range, and waveform independence. DC accuracy benefits from an internal offset-and-averaging algorithm that improves repeatability. AC voltage accuracy reaches 0.02% R + 0.01% FS; AC current achieves 0.1% R + 0.05% FS.
## Technical Specifications
The instrument offers a 160 mS integration period and features standard computing facilities including numerical keyboard and measurement memories. Autoranging capability extends to ratio measurements of widely varying inputs. Full electronic calibration from the front panel eliminates routine cover removal, reducing downtime in production environments.
## Key Features
• 6½–7½ digit floating-point display for enhanced readability
• Log Feedback true RMS for AC measurements with speed and dynamic range
• Proprietary offset-and-average DC measurement technique
