High-Precision AC/DC Calibration with ZX1030E Single-Phase Standard Source
Introduction
The ZX1030E Single-Phase AC/DC Standard Source is a precision instrument designed for calibrating and verifying electrical measurement devices such as AC/DC voltmeters, ammeters, ohmmeters, and multimeters up to 0.2% accuracy. It also serves as a highly stable test source, suitable for validating higher-accuracy instruments (0.2% and above) when used with a reference standard.
Key Features and Technical Highlights
Dual Display Mode
5½-digit LED display shows output values in actual units or percentage.
Wide Output Ranges
AC/DC Voltage: 0–200 mV to 1000 V
AC/DC Current: 0–100 μA to 20 A
Resistance: 10 Ω to 24 MΩ (with ×1 and ×1K multipliers)
Selectable Frequencies
Supports 50 Hz, 60 Hz, and 400 Hz outputs with ≤1% frequency accuracy.
Robust Protection
Automatic overload protection with manual reset.
All voltage and current ranges allow up to 20% overload.
Clamp Meter Support
With an optional standard coil, it extends current measurement to AC 0–750 A (or 1000 A+) and DC 0–1000 A at ±0.3% accuracy.
Performance Comparison
Compared to conventional calibration sources, the ZX1030E offers:
Higher Accuracy:
DC: ±(0.05% reading + 0.02% FS) ±0.02 mV
AC: ±(0.07% reading + 0.03% FS) ±0.04 mV
Resistance: ±0.2% + 20 mΩ
Better Stability:
DC: <0.01% FS/2 minutes
AC: <0.03% FS/2 minutes
Lower Distortion and Ripple:
AC distortion: <0.5%
DC ripple: <0.1%
Technical Specifications
Power Supply: 220 V ±10%, 50 Hz ±1 Hz
Power Consumption: <180 VA
Operating Conditions: 5°C to 35°C, ≤80% RH
Dimensions: 135 × 480 × 420 mm
Weight: 16 kg
Applications
Calibration of analog and digital panel meters, multimeters, and clamp meters.
Used in labs and production lines as a stable voltage/current source.
Compatible with high-accuracy standard meters for secondary calibration.
Conclusion
The ZX1030E combines wide range coverage, high accuracy, and excellent stability, making it an ideal reference source for electrical metrology and calibration workflows. Its ability to support both direct and clamp-meter measurements further enhances its versatility in field and lab applications.
For technicians involved in instrument calibration and electrical testing, the ZX1030E offers a reliable and efficient solution that meets international standards for precision and performance.
