U1251A/U1252A FREQUENCY SPECIFICATIONS
[2]
[1] The additional error to be added as frequency >20 kHz and signal input <10% of range: 3 counts of LSD per kHz.
[2] The input signal is lower than the product of 20,000,000 V-Hz (product of voltage and frequency).
[3] Input current >35 mArms.
[4] 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 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.
[5] Input current < 3 Arms.
