5.2.2 AC current measurement
Current measurement is designed for low and high current respectively with different
methods of connection.
Range for low current: 200uA, 2mA, 20mA, 200mA
Range for high current: 2A, 10A.
Measurement method:
1. Press

Notes: the measured current value is shown on the main display, and the value on
the secondary screen represents the measured frequency of the current input signal
2. Choose different test terminals according to the measurement level. See Fig.
2.2.5 for current of 200mA and below, and connect the red and black test leads
respectively to the proper input terminals. See Fig. 2.2.6 for current from 200mA to 10A,
and connect the red and black test leads respectively to the proper input terminals.
