Ac Current Measurement; Dc Current Measurement (200A Range) - Martindale Electric ET5 Instruction Manual

The AC voltage function defaults to auto ranging and the 5V range.
If the 500mV range is required it is manually selected.
Taking all necessary safety precautions connect the test leads to
the circuit being measured and read the measured voltage from the
lower display.

3.14 AC Current Measurement

Set the rotary switch to the
activate the upper display.
Taking all necessary safety precautions position the fork of
the electrical tester around the conductor to be tested so the
centre of the conductor aligns with and is central to the
marks on the fork.
Read the measured AC current from the upper display.
If required press the SEL button once more to measure the
frequency of the AC current. The frequency value is displayed on
the upper display.
Pressing the SEL button again will return the upper display to the ac
current measurement.

3.15 DC Current Measurement (200A range)

Set the rotary switch to the
