Note: [1] RD is the reading value, RG is the range value; [2] The 0.01 level only supports DC, 45 ~ 65 Hz frequency range. |
• Output range: range below 1 kA (excluding 1 kA): 10%~112%*RG
Range above 1 kA (including 1 kA): 10%~100%*RG (maximum expandable output to 6 kA ）
• Fineness adjustment: 5 ppm*RG, 7-digit decimal display
• DC ripple coefficient: ≤ 0.5% @ 5 kHz or less, AC distortion: ≤ 0.5%.
• Settling time: Using the slow rise output mode, the time to stabilize to the output accuracy is about 3 s
• Protection function: open circuit protection, overload protection, overheating protection
