CAUTION
• Always remove the test leads before replacing the battery.
• Inspect the condition of the test leads and the meter itself for any damage
before operating the meter.
• Use caution when making measurements if the voltage > 35 V DC or V AC
RMS.
• Always discharge capacitors and remove power from the device under test
before performing Diode, Resistance or Continuity tests.
• If the equipment is used in a manner not specified by the manufacturer,
the protection provided by the equipment may be impaired.
• Do not directly view, point, or reflect the laser pointer towards the
eyes.
• Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
