Notes for U1252A AC voltage specifications:
1The additional error to be added as frequency > 20 kHz and signal input <10 %of range: 3 counts of LSD per kHz.
2Input impedance: > 1GHz for 50 mV to 1000 mV. Input impedance is 1.1 MΩ (nominal) with <100 pF for 5 V to 1000 V ranges.
3The input signal is lower than the product of 20,000,000

Notes for U1252B AC current specifications:
1The additional error to be added as frequency > 20 kHz and signal input< 10 % of range: 3 counts of LSD per kHz.
2Input current > 35 µArms.
3Current 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.
4Input current < 3 Arms.
