DANGER
Avoid electrical shock: do not touch the
test leads, tips or the circuit being tested.
Do not try a voltage measurement with the
test leads in the 20A or the mA terminal.
When testing for the presence of voltage or current, make sure
the meter is functioning correctly. Take a reading of a known
voltage or current before accepting a zero reading.
Choose the proper range and function for the measurement. Do
not try voltage or current measurements that may exceed the
ratings marked on the Function/Range switch or terminal.
When measuring current, connect the meter in series with the
load.
Never connect more than one set of test leads to the meter.
Disconnect the live test lead before disconnecting the common
test lead.
The mA and the 20A terminals are protected by fuses. To avoid
possible injury or damage, use only in circuits limited to 400mA
or 20A for 30 seconds.
