IMPORTANT SAFETY WARNINGS

WARNING
Read entire safety notes section regarding potential hazard and proper instructions before using this meter. In this manual the word “WARNING” is used to indicate conditions or actions that may pose physical hazards to the user. The word “CAUTION” is used to indicate conditions or actions that may damage this instrument.
To ensure safe operation and service of the tester, follow these instructions. Failure to observe these warnings can result in severe injuries or death.

  • Before each use, verify meter operation by measuring a known voltage or current.
  • Never use the meter on a circuit with voltages that exceed the category based rating of this meter.
  • Do not use this meter during electrical storms or in wet weather.
  • Do not use the meter or test leads if they appear damaged.
  • Ensure meter leads are fully seated and keep fingers away from the
  • tal probe contact when making measurements. Always grip the leads behind the finger guards molded into the probe.
  • Do not open the meter to replace batteries while the probes are connected.
  • Use caution when working with voltages above 60V DC or 25V AC RMS. Such voltages pose shock hazards.
  • To avoid false readings that can lead to electrical shock, replace batteries if a low battery indicator appears.
  •  Unless measuring voltage or current, shut off and lockout power before measuring resistance or capacitance.
  •  Always adhere to national and local safety codes. Use proper personal protective equipment (PPE) to prevent shock and arc blast injury where hazardous live conductors are exposed.
  •  Always turn off power to a circuit or assembly under test before cutting, unsoldering or breaking the current path. Even small amounts of current can be dangerous.
  • Always disconnect the live test lead before disconnecting the common test lead from the circuit.
  • In the event of electrical shock, ALWAYS bring the victim to the emergency room for evaluation, regardless of victim’s apparent recovery. Electrical shock can cause unstable heart rhythms that may need medical attention.
  • If any of the following occurs during testing, turn off the power source to the circuit being tested: arcing, flame, smoke, extreme heat, smell of burning materials or discoloration melting of components.

WARNING
Higher voltages and currents require greater awareness of physical safety hazards. Before connecting the test leads, turn off power to the circuit under test, set meter to the desired function and range, connect the test leads to the meter first, then connect to the circuit under test. Reapply power. If an erroneous reading is observed, disconnect power immediately and recheck all settings and connections.
This meter is designed for trade professionals who are familiar with the hazards of their trade. Observe all recommended safety procedures that include proper lock-out utilization and use of personal protective equipment that includes safety glasses, gloves and flame resistant clothing.

Test Lead Notes

CATIV 600V Measurement Locations
UEi DL389B TRMS Dual Display Clamp Meter Instruction Manual  & troubleshooting 16

Ensure the test lead shield is pressed firmly in place. Failure to use the CAT IV shield increases arc-flash risk.

CATII 1000V Measurement Locations

UEi DL389B TRMS Dual Display Clamp Meter Instruction Manual  & troubleshooting 17

CAT IV shields may be removed for CAT II locations. This will allow testing on recessed conductors such as standard wall outlets. T ake care not to lose the shields.
WARNING: Test lead category protections apply only to test leads and  should not be confused with the meter’s specific CAT rating. Observe the maximum category protection indicated on the meter the test leads are plugged into.
