Is there anyone helping me with overall accuracy power measurement? Here is the case. Based on the Power analyzer specification, I figured out what voltage error and current error were, which are accuracy. However, my boss asked me to figure out overall accuracy is. I asked him what overall accuracy is. He can't really explain it to me. Can you guys help me to figure out what overall accuracy is?
Specification of products:
Current Meter reading ±( 0.05%reading + 0.1%range + 1digit):
Power Meter reading ±( 0.04%reading + 0.04%range + 1digit):
Voltage Meter reading based on ±( 0.05%reading + 0.1%range + 1digit):
Input Range (RMS)
Voltage CF=3: 15/30/60/150/300/600V
Current CF=3:0.5/1/2/5/10/20A
Voltage Meter reading based on ±( 0.05%reading + 0.1%range + 1digit):
When Input voltage is 277V, the error range equals to 276.561V to 277.44 (277±277*0.05%+300*0.1%+0.001)
Number Name Reading Range 1 digit Low High Error
Voltage(V) 277 300 0.001 276.5605 277.4395 0.15866%
Current (A) 5 10 0.0001 4.9874 5.0126 0.25200%
Power (W) 1385 3000 0.0001 1383.246 1386.754 0.12665%
Thanks
