[1] Input impedance: Refer to Table A on page 8.

[2] Crest factor ≤ 3.0 at full scale, 5.0 at half scale except the 1000 mV and 1000 V ranges where it is 1.5 at full scale, 3.0 at half scale.

For non-sinusoidal waveform, add 0.1% of reading 0.3% of range.

[3] The additional error to be added as frequency >20 kHz and signal input <10% of range: 3 counts of LSD per kHz.

[4] The input signal is lower than 20,000,000 V-Hz (the product of voltage and frequency).

[5] Input current >35 µArms.

[6] Current can be measured from 2.5 A up to 10 A continuously. An additional 0.5% needs to be added to the speciﬁed accuracy if the signal measured is in the range

of 10 A ~ 20 A for 30 seconds maximum. After measuring a current of >10 A, leave the meter to cool down for twice the measuring time used before application of

low current measurement.

[7] Input current < 3 Arms.

[8] For non-square wave signals, add 5 counts.
