Product Introduction

The XL-9600 DC Standard Source (DC Energy Meter Calibration Device) series is based on the "JJG-842-2017 Electronic DC Meter Calibration Regulations" and "GBT 33708-2017 Static DC Energy Meter" (co-drafted by Xinglong Technology). It can serve as a standard voltage source, standard current source, standard small signal voltage source, direct or indirect standard power source, and standard energy meter calibration device. It meets the output requirements for DC voltage, current, small signal voltage amplitude, power, and energy with accuracy levels of 0.05/0.02 (voltage and current) and 0.1/0.05 (energy). It is suitable for DC testing and calibration, applicable to State Grid Metrology Centers, research institutions, energy meter manufacturers, and enterprises related to DC metering.
 

Functional Features
 

• High Output Accuracy: Power and Energy Output Accuracy Level 0.1/0.05 Level Optional Voltage and Current Output Accuracy Level 0.05/0.02 Level Optional, suitable for DC metering and calibration.
• Wide Output Range: Output Range 10mV-1150V, 100uA-600A, 100uV-5V Meets the testing and calibration requirements of DC voltmeters, DC ammeters, small signal voltmeters, DC wattmeters, DC energy meters, and other DC metering devices.
• Automatic Range Switching Across Full Output Range: Voltage, current, and small signal voltage automatically switch to appropriate output ranges throughout the entire output range to ensure accuracy indicators across the full output range.
• Superimposed Ripple Output: Voltage, current, and small signal voltage can superimpose ripple output with frequencies of 20-500Hz ripple output to calibrate the ripple effect on DC energy meters.
• Comprehensive Calibration Items: Meets the "JJG-842-2017 Electronic DC Meter Calibration Regulations" requirements for creep test, start-up test, basic error, instrument constant test, and clock daily timing error.
• High Small Signal Accuracy: Output uses 4-wire feedback output to eliminate the influence of line impedance on small signal output, ensuring small signal output accuracy.
• High Output Stability: Uses linear power amplifier, typical output stability can reach 0.005%RG/min 。
• Auxiliary Power Supply (some models): Built-in 12V, 24V DC, 220V AC three types of auxiliary power outputs and supports ±20% adjustable to meet power supply voltage variation test requirements.
• High Accuracy Second Pulse: Built-in high accuracy crystal oscillator clock, typical accuracy is 200ns/s convenient for clock testing and calibration.
• Safe, Reliable, and Flexible Use: Voltage and current (including direct and indirect current) are fully electrically isolated. Accurate measurement can be achieved regardless of whether the measured voltage and current are isolated or whether voltage and current share high or low terminals .
• Professional Software: Supports automatic or semi-automatic calibration of DC energy meters, supports calibration data recording and management, and can automatically generate calibration certificates according to templates after calibration, with freely editable templates.
• Human-Machine Interaction, Simple and Flexible: Equipped with a large touch display screen, clear and intuitive value display, and multiple interfaces including RJ45, RS232, and USB, facilitating the construction of automatic test systems.
