  • Page 13: Battery Installation

    BATTERY INSTALLATION WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery cover. 1. Disconnect the test leads from the meter. 2. Remove the rear battery cover by removing the two screws using a Phillips head screwdriver.

  • Page 14: 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. Press the HOLD button to freeze a displayed reading NOTE: On some low AC and DC voltage ranges, with the test leads not connected to a device, the display may show a random, changing reading.

  • Page 15: Non-Contact Ac Voltage Detector

    NON-CONTACT AC VOLTAGE DETECTOR The EX330 can detect the presence of AC voltage (from 100 to 600VAC) simply by being held very near to a voltage source. WARNING: Test the AC voltage detector on a known live circuit before each use. WARNING: Before using the meter in the AC Voltage Detector mode, verify that the battery is fresh by confirming characters appear on the LCD when the function dial is turned to any...

  • Page 16: 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 17: Dc Voltage Measurements

    DC VOLTAGE MEASUREMENTS CAUTION: Do not measure DC voltages if a motor on the circuit is being switched ON or OFF. Large voltage surges may occur that can damage the meter. Set the function switch to the VDC position. Insert the black test lead banana plug into the negative COM jack.

  • Page 18: Ac / Dc Current Measurements

    AC / DC CURRENT MEASUREMENTS CAUTION: Do not make current measurements at 10 Amps for longer than 30 seconds. Exceeding 30 seconds may cause damage to the meter and/or the test leads. Insert the black test lead banana plug into the negative COM jack.

  • Page 19: 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. Set the function switch to the ! position. Insert the black test lead banana plug into the negative COM jack.

  • Page 20: Continuity Check

    CONTINUITY CHECK WARNING: To avoid electric shock, never measure continuity on circuits or wires that have voltage on them. Set the function switch to the position. Insert the black lead banana plug into the negative COM jack. Insert the red test lead banana plug into the positive ! jack.

  • Page 24: Contact Temperature Measurements

    CONTACT TEMPERATURE MEASUREMENTS Set the function switch to the ºF or ºC position. Insert the Temperature Probe into the input jacks, making sure to observe polarity. The probe can be pressed against a device under test to read its temperature or the probe can be held in air to read the ambient temperature.

  • Page 25: Auto-Manual Range Selection

    AUTO-MANUAL RANGE SELECTION When the meter is first turned on, it automatically goes into the Auto Range mode. 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: Press the RANGE key.

  • Page 26: Maintenance

    MAINTENANCE WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the back cover or the battery or fuse covers. WARNING: To avoid electric shock, do not operate your meter until the battery and fuse covers are in place and fastened securely.

  • Page 27: Low Battery Indication

    LOW BATTERY INDICATION WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery cover. LOW BATTERY INDICATION icon will appear in the lower left-hand corner of the display when the battery voltage becomes low. Replace the batteries when this appears.
