I. Applications and Features:
XF30B-2Multi-functional Calibration InstrumentSuitable for calibration and verification of various current and voltage meters below 0.2 class. Also serves as a high-stability test power source, when paired with high-grade standard meters, for calibration of current and voltage meters above 0.2 class.
II. Main Features:
1：51/2The LED digital display has output volume, which can be shown in actual value or percentage format.
2: Output range for AC and DC current is 0~100uA~500uA~2mA~5mA~20mA~50mA~200mA~500mA~2A~5A~20A.
3：AC/DC VoltageOutput range: 0~200mV~1V~2V~5V~10V~20V~50V~100V~200V~500V~1000V.
4: Available frequencies for selection include three types: 50Hz, 60Hz, and 400Hz.
5: Overload protection with automatic shutdown and manual reset.
Each voltage and current level can withstand an overload of 20%.
7: Clamp Meter Measurement: Equipped with our standard coil, capable of measuring AC 0～750A (some models can measure up to over 1000A); DC 0～1000A with an error of ±0.3%.
III. Technical Performance:
Stability: DC < FullRange0.01% / 2 minutes
AC < FullRange0.03% / 2 minutes
2: Communication Distortion: <0.5%
3: Direct Current Ripple Factor: ＜0.1%
4: Output Frequency & Accuracy: 50Hz / 60Hz / 400Hz < 1%
