Electrical measurement standard source
The MOEORW-W3067 electrical measurement standard source, also known as a multi-functional calibrator, is a high-precision AC/DC signal generator and a professional standard instrument for the calibration and verification of electrical measuring instruments.
It features a wide output range, high accuracy, strong stability, multiple adjustment modes, multiple automatic protections, and convenient operation.
Suitable for departments involved in instrument manufacturing, repair, and metrology verification, for calibrating various voltage, current, and resistance meters.
Product Introduction
The MOEORW-W3067 electrical measurement standard source (hereinafter referred to as the standard source) is an AC/DC standard voltage and current generator with a six-digit LCD display output value. It can be used for calibration, verification, and measurement of digital and pointer-type multimeters and various voltage and current meters of grade 0.2 and below. A standard resistor bank is also provided for convenient calibration of resistance meters.
The standard source employs a new type of composite high-power amplifier, offering high output power, high reliability, and low distortion. A superior 16-bit A/D converter chip significantly improves conversion speed and accuracy; the AC/DC converter uses a true RMS chip, ensuring accurate AC output and better linearity. The window simultaneously displays the actual output value, percentage, and frequency. Output adjustment can be performed either by bit or by percentage. The entire unit adopts a closed-loop control circuit design, greatly improving output stability. The unit also features automatic overvoltage and overcurrent protection.
This standard provides 22 AC/DC voltage output ranges (0~1000V); 22 AC/DC current output ranges (0~30A); 11×2 ranges of medium-value resistance (10Ω~20MΩ); and AC frequencies of 50Hz, 60Hz, and 400Hz (digitally synthesized, selectable via buttons). All these parameters and ranges are switched via precision switches. It features digital display, wide range, fine range division, high accuracy, good stability, and ease of use. It is widely used by instrument manufacturing, repair, and metrology verification departments.
