CAPACITANCE SPECIFICATIONS
FREQUENCY SPECIFICATIONS
[1] The additional error to be added as frequency >20 kHz and signal input <10% of range: 3 counts of LSD per kHz.
[2] The input signal is lower than 20,000,000 V-Hz (the product of voltage and frequency).
[3] Input current >35 µArms.
[4] Current can be measured from 2.5 A up to 10 A continuously. An additional 0.5% needs to be added to the specifi ed accuracy if the signal measured is in the range
[5] Input current < 3 Arms.
[6] For non-square wave signals, add 5 counts.
