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 battery observing the correct polarity. 5. Insert the new battery into the battery holder. 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.
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. 2. For current measurements up to 200mA DC, set the function switch to the 200mA DC position and insert the red test lead banana plug into the (mA) jack. 3.
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 !! position. 2. Insert the black test lead banana plug into the negative (COM) jack Insert the red test lead banana plug into the positive ! jack. 3. Touch the test probe tips across the circuit or part under test.
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 0.4V to 0.7V. Reverse voltage will indicate “1”. Shorted devices will indicate near 0mV. Shorted devices will indicate near 0mV and an open device will indicate “1” in both polarities. CONTINUITY TEST 1.
BATTERY TEST 1. Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the positive V jack. 2. Select the 1.5V or 9V BAT position using the function switch. 3. Connect the red test lead to the positive side of the 1.5V or 9V battery and the black test lead to the negative side of the 1.5V or 9V battery. 4. Read the voltage in the display. Good Weak 9V battery: >8.2V 7.2 to 8.2V 1.5V battery: >1.35V 1.22 to 1.35V Bad <7.2V <1.
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 cover. WARNING: To avoid electric shock, do not operate your meter until the battery and fuse cover are 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. If it gets wet, wipe it off. 2. USE AND STORE THE METER IN NORMAL TEMPERATURES.
REPLACING THE BATTERY WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery cover. 1. When the battery become exhausted or drop below the operating voltage, “ ” will appear in the lower left corner of the LCD display. The battery should be replaced. 2. Follow instructions for installing battery. 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 battery is 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.
