Specifications - Matco Tools ADMM50 Operating Instructions Manual

Always inspect the tester, test leads and any other acces-
sories for damage prior to every use. If any damage is found,
do not use tester until repairs are done.
Always consider electrical and electronic equipment to be ener-
gized (live). Never assume any equipment is de-energized.
Do not connect probes to any available (unused) terminal
while the meter is connected to a hazardous live circuit.
Never ground yourself when taking electrical measurements.
Isolate yourself from ground by using dry rubber insulating
mats to cover all exposed/grounded metal. Stand on rubber
mats and wear dry clothing.
Never take resistance measurements on energized (live)
electrical or electronic equipment.
Use one hand, instead of two, whenever possible to take
measurements. If two hands must be used, use extreme
caution not to contact any energized conductors with your
hands. Be certain test leads are dry and clean.
Do not hold the tester when taking measurements. Place the
tester on a clean, insulating surface prior to taking any
measurement.
Don't become part of the circuit. Think safety. Act safely.
If working on a vehicle, take the following added precautions:
Only work on vehicle in a well ventilated area.
Always wear safety eye protection.
Avoid moving fan blades or any potentially moving parts.
Avoid hot engine parts.
Put transmission in "park" (automatic transmission vehicles) or
"neutral" (manual transmission vehicles). Set the parking brake.
Turn the ignition "off" before connecting or disconnecting
any testing equipment.
Put blocks on drive wheels.
Avoid wearing loose clothing or jewelry when working on a
vehicle.
Read your vehicle's service manual and follow it's safety
