Safety
DANGER
Engines produce carbon monoxide which is
odorless, can cause slower reaction time and
can lead to serious injury. When the engine is
operating, always keep service areas WELL
VENTILATED or attach the vehicle exhaust
system to the shop exhaust removal system.
Set the parking brake and block the wheels
before testing or repairing the vehicle. It is
especially important to block the wheels on
front-wheel drive vehicles; the parking brake
does not hold the drive wheels.
Wear an eye shield when testing or repairing
vehicles.
Exceeding the limits of this meter is dangerous.
This may expose you to serious or possibly fatal
injury. Carefully read and understand the
cautions and the specification limits of this
meter.
Voltage between any terminal and ground
must not exceed 600V DC or 600V AC.
Use caution when measuring voltage above
25VDC or 25VAC.
Circuit tested must be protected by a 20A fuse or circuit breaker.
Do not use the meter if it has been damaged.
Do not use any test leads if the insulation is damaged or if metal is
exposed.

…
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 on circuits limited to 400mA or
20A for 30 seconds.
