Notes for U1251B AC voltage specifications:
1 Input impedance: Refer to Ta b l e 7 - 1 9 .
2 AC mV/V and AC µA/mA/A specifications 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 1000 mV and 1000 V ranges, where the crest factor is 1.5 at full
scale and 3 at half scale.

Notes for U1251B AC current specifications:
1 AC mV/V and AC µA/mA/A specifications 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 1000 mV and 1000 V ranges, where the crest factor is 1.5 at full
scale and 3 at half scale.
2 Input current > 35 µArms.
3 Current can be measured from 2.5 A up to 10 A continuously. Add 0.5% to the specified accuracy if the signal measured is
in the range of 10 A to 20 A and for a period of up to 30 seconds. After measuring current > 10 A, leave the meter to cool
down for a period that is twice the measuring time used before application of low current measurement.
4 Input current < 3 Arms.
