• Shunt resistance

• 0.01 W to 100 W for 500 μA to 10 A ranges

• Response time

• Approximate 1.0 second when the displayed reading reaches 99.9% DC value of the tested

input signal at the same range.

AC voltage (True RMS AC Coupling Mode)

• Measurement method

• AC coupled true RMS – measure the AC component with up to 400 VDC bias on any range

• Crest factor

• Maximum 3:0 at full scale

• Input impedance

• 1 MΩ in parallel with <100 pF of all ranges

• Maximum input voltage
