    8.1 Replacing the Batteries 8.1 Replacing the Batteries • To avoid electric shock when replacing the batteries, first disconnect the test leads from the object to be measured. • Do not mix old and new batteries, or different types of batteries.
  • Page 103 8.1 Replacing the Batteries • To avoid corrosion from battery leakage, remove the batteries from the instrument if it is to be stored for a long time. • The supplied battery pack contains NiMH batteries. Continuing to operate the meter when the indicator appears can over- discharge the batteries and shorten their useful life.
