DC and AC Current Measurement
WARNING
• Before measuring current, ALWAYS
make sure the power supply for the
circuit has been switched off. Check
if the leads are connected to the
correct input terminals and that the
rotary switch has been turned to the
correct measurement range.
• ALWAYS connect the test leads in
series. DO NOT connect the test
leads in parallel with any circuit while
taking measurements. Doing so may
result in damage to the multimeter or
injury to the user. [Figure 4.1]
• If the current being tested is greater
than 10A, measure the current for
less than 10 seconds, then wait at
least 15 minutes before taking the
next measurement.
