Safety Information
Understand and follow operating instructions carefully. Use the meter only as specified in this manual; otherwise, the protection provided by the meter may be impaired.

WARNING

• When using test leads or probes, keep your fingers behind the finger guards.
• Remove the test lead from the Meter before opening the battery door or Meter case.
• Use the Meter only as specified in this manual or the protection by the Meter might be impaired.
• Always use proper terminals, switch positions, and range for measurements.
• Never attempt a voltage measurement with the test lead inserted into the A input terminal.
• Verify the Meter’s operation by measuring a known voltage. If in doubt, have the Meter serviced.
• Do not apply more than the rated voltage, as marked on the Meter, between terminals or between any terminal and earth ground.
• Do not attempt a current measurement when the open voltage is above the fuse protection rating. Suspected open circuit voltage can be checked with the voltage function.
• Only replace the blown fuse with the proper rating as specified in this manual.
• Use caution with voltages above 30 Vac rms, 42 Vac peak, or 60 Vdc. These voltages pose a shock hazard.
• To avoid false readings that can lead to electric shock and injury, replace the battery as soon as the low battery indicator <appears.
• Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, diodes, or capacitance.
• Do not use Meter around explosive gas or vapor.
• To reduce the risk of fire or electric shock do not expose this product to rain or moisture.

Caution

• Disconnect the test leads from the test points before changing the position of the function rotary switch.
• Never connect a source of voltage with the function rotary switch in Ω/ / A / /Hz position.
• Do not expose the Meter to extremes in temperature or high humidity.
• Never set the meter in A function to measure the voltage of a power supply circuit in equipment that could result in damage the meter and the equipment under test.

Non-Contact Voltage (Volt sense)

1. Volt sense switch will be activated on any function or at OFF status.
2. Test leads are not used for the Volt sense test.
3. Press the Volt sense button. The display goes black, a tone sounds and the red LED lights up to verify the instrument is operational. The Volt sense button must be held down to detect the presence of voltage without use of the leads.
4. If a voltage of 50V to 600V (50 to 500Hz) is detected near the top of the meter a continuous tone sounds and the red LED near the top of the meter Illuminates.

Refer to the following figure to replace the fuse

Caution

• Use only a fuse with the amperage, interrupt, voltage, and speed rating specified.
• Fuse rating: 10A, 500V

Battery Replacement
Refer to the following figure to replace the batteries

Caution

• Replace the batteries as soon as the low batteries indicator ” ” appears, to avoid false reading.
