1. Improper use of this meter can cause damage, shock, injury or death.

Read and understand this user manual before operating the meter.

2. Make sure any covers or battery doors are properly closed and ured.

3. Always remove the test leads before replacing the battery or fuses.

4. Inspect the condition of the test leads and the meter itself for any

damage before operating the meter. Repair any damage before use.

5. Do not exceed the maximum rated input limits.

6. Use great care when making measurements if the voltages are

greater than 25VAC rms or 35VDC. These voltages are considered a

shock hazard.

7. Always discharge capacitors and remove power from the device

under test before performing Diode, Resistance or Continuity tests.

8. Remove the battery from the meter if the meter is to be stored for

long periods.

9. To avoid electric shock, do not measure AC current on any circuit

whose voltage exceeds 250V AC.
