[1] Input 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.
[2] The input signal is lower than the product of 20,000,000 V-Hz (product of voltage
and frequency).
[3] Input current >35 μArms.
[4] 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.
[5] Input current < 3 Arms.
