  • Page 1 User's Guide Digital Multimeter Extech 410...
  • Page 2 Introduction Congratulations on your purchase of the Extech EX410 Multimeter. This meter measures AC/DC Voltage, AC/DC Current, Resistance, Diode Test, and Continuity plus Thermocouple Temperature. Proper use and care of this meter will provide many years of reliable service. Safety International Safety Symbols This symbol, adjacent to another symbol or terminal, indicates the user must refer to the manual for further information.
  • Page 3 CAUTIONS • Improper use of this meter can cause damage, shock, injury or death. Read and understand this user manual before operating the meter. • Always remove the test leads before replacing the battery or fuses. • Inspect the condition of the test leads and the meter itself for any damage before operating the meter.

  • Page 4: Overvoltage Category

    OVERVOLTAGE CATEGORY III This meter meets the IEC 610-1-2001 standard for OVERVOLTAGE CATEGORY III. Cat III meters are protected against overvoltage transients in fixed installation at the distribution level. Examples include switches in the fixed installation and some equipment for industrial use with permanent connection to the fixed installation.

  • Page 6: Dc Voltage Measurements

    Operating Instructions WARNING: Risk of electrocution. High-voltage circuits, both AC and DC, are very dangerous and should be measured with great care. 1. ALWAYS turn the function switch to the OFF position when the meter is not in use. 2. If “1 ” appears in the display during a measurement, the value exceeds the range you have selected.

  • Page 7: Ac Voltage Measurements

    AC VOLTAGE MEASUREMENTS WARNING: Risk of Electrocution. The probe tips may not be long enough to contact the live parts inside some 240V outlets for appliances because the contacts are recessed deep in the outlets. As a result, the reading may show 0 volts when the outlet actually has voltage on it.

  • Page 8: Ac Current Measurements

    AC CURRENT MEASUREMENTS CAUTION: Do not make current measurements on the 20A scale for longer than 30 seconds. Exceeding 30 seconds may cause damage to the meter and/or the test leads. 1. Insert the black test lead banana plug into the negative COM jack.

  • Page 9: Continuity Check

    CONTINUITY CHECK WARNING: To avoid electric shock, never measure continuity on circuits or wires that have voltage on them. 1. Set the function switch to the position. 2. Insert the black lead banana plug into the negative COM jack. Insert the red test lead banana plug into the positive Ω jack. 3.
  • Page 10 TEMPERATURE MEASUREMENTS 1. Set the function switch to the TEMP position. 2. Insert the Temperature Probe into the Temperature Socket, making sure to observe the correct polarity. 3. Press the ºC or ºF button for the desired units. 4. Touch the Temperature Probe head to the part whose temperature you wish to measure.
