Pre-Operation Inspection

Before each use, inspect your tool and correct any problems to reduce the
risk of serious injury from electric shock and other causes and prevent
tool damage.
1. Make sure the unit is OFF and the leads are not connected.
2. Clean any oil, grease or dirt from the equipment. This aids inspection and helps pre-
vent the tool from slipping from your grip.
3. Inspect the tool.
• For any broken, worn, missing or binding parts or any condition which may prevent
safe and normal operation.
• Con rm that battery compartment cover and back cover (fuse cover) are properly
secured.
• Inspect the test leads for damaged insulation or exposed wire. Check the test leads
for continuity.
• Check that the markings and warning label are present, rmly attached and read-
able.
If any issues are found during the inspection, do not use the tool until it has been properly
serviced.
4. Verify the meter operation (following the Set-Up and Operation Instructions).
• Turn the unit ON and con rm that the Low Battery icon is not ON.
• Perform a continuity test.
5. Do not use the meter if it operates abnormally. When in doubt, have the meter ser-
viced.
