•
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 cau-
tion 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 meas-
urement.
•
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 pro-
cedures.
