    Safety This meter is intended for origin of installation use and protected, against the users, by double insulation per EN61010-1 and IEC61010-1 2 Edition (2001) to Category IV 600V and Category III 1000V; Pollution Degree 2. The meter also meets UL 61010-1, 2 Edition (2004), CAN/CSA C22.2 No.

  • Page 11: Battery Installation

    BATTERY INSTALLATION WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery cover. 1. Turn power off and disconnect the test leads from the meter. 2. Open the rear battery cover by removing two screws (B) using a Phillips head screwdriver.

  • Page 12: Operating Instructions

    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 “OL” appears in the display during a measurement, the value exceeds the range you have selected.

  • Page 13: Ac Voltage Measurements

    AC VOLTAGE (Frequency, Duty Cycle) MEASUREMENTS AC VOLTAGE: 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 14: Dc Current Measurements

    DC 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 15: Ac Current Measurements

    AC CURRENT (Frequency, Duty Cycle) 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 16: Resistance Measurements

    RESISTANCE MEASUREMENTS WARNING: To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any resistance measurements. Remove the batteries and unplug the line cords. 1. Set the function switch to the ΩCAP position. 2.

  • Page 17: 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 Ω CAP position. 2. Insert the black lead banana plug into the negative COM jack. Insert the red test lead banana plug into the positive ...

  • Page 18: Capacitance Measurements

    CAPACITANCE MEASUREMENTS WARNING: To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any capacitance measurements. Remove the batteries and unplug the line cords. 1. Set the rotary function switch to the Ω CAP position.

  • Page 19: Temperature Measurements

    Note: The supplied thermocouple is rated for 482°F (250°C). For higher temperatures you can purchase a high temperature thermocouple from www.craftsman.com. FREQUENCY SENSITIVITY (ELECTRICAL) The frequency sensitivity is range dependent when the function is selected from while in the voltage or current measuring function.

  • Page 20: Autoranging/manual Range Selection

    AUTORANGING/MANUAL RANGE SELECTION When the meter is first turned on, it automatically goes into Autoranging. This automatically selects the best range for the measurements being made and is generally the best mode for most measurements. For measurement situations requiring that a range be manually selected, perform the following: 1.

  • Page 21: Auto Power Off

    AUTO POWER OFF The auto off feature will turn the meter off after 30 minutes. To disable the auto power off feature, hold down the MODE button and turn the meter on. LOW BATTERY INDICATION icon will appear in the display when the battery voltage becomes low.

  • Page 22: Maintenance

    MAINTENANCE WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the back cover or the battery cover. WARNING: To avoid electric shock, do not operate your meter until the battery cover is in place and fastened securely. This multimeter is designed to provide years of dependable service, if the following care instructions are performed: 1.
