4.2Accuracy index
Accuracy: ±( % reading + the number of characters),
gurantee for one year.
Base condition: ambient temperature is from
18˚C to 28˚C, relative humidity is not greater than 80%
• When making AC current measurement, please position
the conductor to the center If the conductor is not
positioned at the center, the max. additional error
resulted is 1.5%.
