I. Usage, Features:
DO30-E+ Digital Triple-Function Meter Calibrator, Multi-Function Calibration Instrument is suitable for calibration of various 0.5-class and below current, voltage, and multi-meters. It can also be used as a high-stability test power supply, paired with high-grade standard meters, for calibration of 0.5-class and above current and voltage meters.
II. Main Functions:
1. 5 1/2-digit LED digital display for output quantity, available in both actual value and percentage formats.
2. DC and AC current output range: 0~100uA~500uA~2mA~5mA~20mA~50mA~200mA~500mA~2A~5A~20A.
3. Output voltage range for AC and DC: 0 to 200mV to 1V to 2V to 5V to 10V to 20V to 50V to 100V to 200V to 500V to 1000V.
4. Available frequency options include three types: 50Hz, 60Hz, and 400Hz
5. Overload protection with automatic shutdown and manual reset.
6. Each voltage and current rating can withstand an overload of 20%.
7. Clamping meter measurement function: Equipped with our standard coil, capable of measuring AC 0-1000A; error ±0.3%.
