How To Perform Current Testing
In most electronic troubleshooting and repair, you will rarely take current
measurements. Most general purpose digital multimeters allow you to
measure AC current (ACA or Iac) and DC current (DCA or Idc) in a
circuit, although there are often few ranges to choose from. Normally
analogue meter do not have the AC current range.
As with voltage measurements, current is measured in a working circuit
with power applied, but current must be measured in series with the
circuit or component under test.
