Notes for U1252B AC + DC voltage specifications:
1 The additional error to be added as frequency > 15 kHz and signal input < 10 %of range: 3 counts of LSD per kHz.
2 Input impedance: Refer to

Table 7-7 U1252B true RMS ac+dc current specifications

Function
500.00 µA
Current
Notes for U1252B AC + DCcurrent 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.
