Warning:
 Pre-requisites: Remove the power from the circuit before connecting the test
leads to the DUT.
 Select the correct terminal input and turn the rotary switch to select the
measurement function. If the correct range is not known, select the highest
range and work your way down to a lower range if needed.
 Fuses are located on the mA and 10A current input terminals. Never attempt
connecting the test leads to any circuits that are connected to mains power.
 For safety purposes, ensure each measurement over 5A is performed for less
than 10 seconds with a 15 minute interval between measurements.
