[1] Input impedance: Refer to Table A on page 9.
[2] AC mV/V and AC µA/mA/A specifi cations are true RMS AC coupled, valid from 5% to 100% of range. The crest factor may be up to 3 at full scale, up to 5 at half- scale, except for
[3] For U1251A / U1252A / U1253A, the input signal is lower than 20,000,000 V-Hz (the product of voltage and frequency).
[4] Input current >35 µArms.
[5] 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 of 10 A ~ 20 A for 30
[6] Input current < 3 Arms.
[7] The additional error to be added as frequency >20 kHz and signal input <10% of range: 3 counts of LSD per kHz.
[8] The additional error to be added as frequency >15 kHz and signal input <10% of range: 3 counts of LSD per kHz.
[9] 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
1000 mV and 1000 V ranges, where the crest factor is 1.5 at full scale and 3 at half scale.
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.
