BATTERY INSTALLATION WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery door. 1. Disconnect the test leads from the meter. 2. Remove the protective rubber holster (if installed). 3. Open the battery door by loosening the screw using a Phillips head screwdriver.
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.
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.
DC CURRENT MEASUREMENTS CAUTION: Do not make current measurements on the 10A 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.
AC CURRENT MEASUREMENTS CAUTION: Do not make current measurements on the 10A 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.
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 highest Ω position. 2.
DIODE TEST 1. Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the positive diode jack. 2. Turn the function switch to the / •))) position. 3. Touch the test probes to the diode under test. Forward voltage will indicate 400 to 700mV.
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 doors. WARNING: To avoid electric shock, do not operate your meter until the battery and fuse doors are in place and fastened securely. This MultiMeter is designed to provide years of dependable service, if the following care instructions are performed: 1.
REPLACING BATTERIES WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery door. 1. When the batteries become exhausted or drop below the operating voltage, “ ” will appear in the lower left corner of the LCD display. The batteries should be replaced.
