Notes for U1252A AC +DC voltage 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 Input impedance: > 1 GW for 50 mV to 1000 mV. Input impedance is 1.1 MΩ (nominal) with <100 pF for 5 V to 1000 V
ranges.
3 The input signal is lower than the product of 20,000,000 V-Hz (product of voltage and frequency).

Notes for U1252A AC +DC current specifications:
1 Input current > 35 µArms.
2 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.
3 Input current < 3 Arms.
