BATTERY INSTALLATION WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery/fuse cover. 1. Disconnect the test leads from the meter. 2. Remove the rubber holster (if in place). 3. Remove the two screws securing the rear cover using a Phillips head screwdriver. 4. Lift the cover off and replace the batteries observing the correct polarity. 5. Insert the new batteries into the battery holder. 6. Replace the rear cover and secure with the screws.
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. This is normal and is caused by the high-input sensitivity.
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. Make sure the probe tips are touching the metal contacts inside the outlet before assuming that no voltage is present. CAUTION: Do not measure AC voltages if a motor on the circuit is being switched ON or OFF.
AC/DC CURRENT MEASUREMENTS CAUTION: Do not make high current measurements on the 10A scale for longer than 15 seconds followed by a 15 minute cool down period. Exceeding 15 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. 2. For current measurements up to 4000 A, set the function switch to the A position and insert the red test lead banana plug into the mA jack. 3.
RESISTANCE MEASUREMENTS 1. Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the positive jack. 2. Set the function switch to the position. 3. Touch the test probe tips across the circuit or part under test. It is best to disconnect one side of the part under test so the rest of the circuit will not interfere with the resistance reading. 4. Read the resistance in the display. CAPACITANCE MEASUREMENTS 1.
TEMPERATURE MEASUREMENTS WARNING: To avoid electric shock, disconnect test leads from any source of voltage before making a temperature measurement. Be sure that the thermocouple has been removed before changing to any other measurement function. 1. Insert the type K thermocouple probe into the Temp and COM jacks. o o 2. Turn the rotary switch to the F or C position. 3. Read the temperature on the display. CONTINUITY MEASUREMENTS 1.
DIODE MEASUREMENTS 1. Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the positive V/ /mA jack. 2. Turn the rotary switch to the •))) position. 3. Touch the test probes to the diode under test. Forward voltage will indicate 0.4V to 0.7V. Reverse voltage will indicate “OL”. Shorted devices will indicate near 0mV and an open device will indicate “OL” in both polarities. DATA HOLD Press the Hold button to freeze the reading in the display.
MAINTENANCE WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery/fuse cover. WARNING: To avoid electric shock, do not operate your meter until the battery/fuse 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.Keep the meter dry. 2.Use and store the meter in mild ambient conditions.
REPLACING THE BATTERIES WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery cover. 1. When the batteries become exhausted or drop below the operating voltage, “ ” will appear in the LCD display. The batteries should be replaced. 2. Follow instructions for installing batteries. See the Battery Installation section of this manual. 3. Dispose of the old batteries properly.
TROUBLESHOOTING There may be times when your meter does not operate properly. Here are some common problems that you may have and some easy solutions to them. Meter Does Not Operate: 1. Always read all the instructions in this manual before use. 2. Check to be sure the batteries are properly installed. 3. Check to be sure the battery is good. 4. If the battery is good and the meter still does not operate, check to be sure that both ends of the fuse are properly installed.
