Performance Tests
The following performance tests verify the complete operability of the Meter and check the
accuracy of each Meter function against the Meter’s specifications.
Accuracy specifications are valid for a period of one year after calibration, when measured at an
operating temperature of 18°C to 28°C and a maximum of 80% relative humidity.
To perform the following tests, it is not necessary to open the case, no adjustments are necessary,
merely make the required connections, apply the designated inputs, determine if the reading on the
Meter display falls within the acceptable range indicated.
If the Meter fails any of these tests, it needs calibration adjustment or repair.
Testing the Display

position to hold the display in the
Display Test Mode. Compare the display with the example in Figure 2. Turn off the meter to

Maintenance - continued
To reduce the risk of personal injury and damage, never immerse your tool, battery pack or
charger in liquid or allow a liquid to flow inside them.
Maintaining Tool
Keep your tool, battery pack and charger in good repair by adopting a regular maintenance program.
After six months to one year, depending on use, return the tool, battery pack and charger to a
MILWAUKEE service facility for service. If the tool does not start or operate at full power with a fully
charged battery pack, clean the contacts on the battery pack. If the tool still does not work properly,
return the tool, charger and battery pack, to a MILWAUKEE service facility for repairs.
Cleaning
Clean dust and debris from charger and tool vents. Keep tool handles clean, dry and free of oil or grease.
Use only mild soap and a damp cloth to clean the tool, battery pack and charger since certain cleaning
agents and solvents are harmful to plastics and other insulated parts. Some of these include gasoline,
turpentine, lacquer thinner, paint thinner, chlorinated cleaning solvents, ammonia and household deter-
gents containing ammonia. Never use flammable or combustible solvents around tools.
