ONE YEAR FULL WARRANTY ONE YEAR FULL WARRANTY ON CRAFTSMAN MANUAL RANGING MULTIMETER If this CRAFTSMAN Manual Ranging MultiMeter fails to give complete satisfaction within one year from the date of purchase, RETURN IT TO THE NEAREST SEARS STORE OR OTHER CRAFTSMAN OUTLET IN THE UNITED STATES, and Sears will replace it, free of charge. If this CRAFTSMAN Manual Ranging MultiMeter is used for commercial or rental purposes, this warranty applies for 90 days from the date of purchase.
SAFETY INSTRUCTIONS This meter has been designed for safe use, but must be operated with caution. The rules listed below must be carefully followed for safe operation. 1. NEVER apply voltage or current to the meter that exceeds the specified maximum: Function VAC V DC or V AC mA DC A DC Resistance, Continuity Input Limits Maximum Input 600V DC/AC 600V DC/AC, 200Vrms on 200mV range 200mA 250V fast acting fuse 10A 250V fast acting fuse(30 seconds max every 15 minutes) 250Vrms for 15sec max 2.
SAFETY SYMBOLS This symbol adjacent to another symbol, terminal or operating device indicates that the operator must refer to an explanation in the Operating Instructions to avoid personal injury or damage to the meter. WARNING This WARNING symbol indicates a potentially hazardous situation, which if not avoided, could result in death or serious injury. CAUTION This CAUTION symbol indicates a potentially hazardous situation, which if not avoided, may result damage to the product.

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. 4. Insert the battery into battery holder, observing the correct polarity. 5. Put the battery door back in place. Secure with the screw.
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. Change to a higher range. 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.
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 highest DC mA 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 rotary switch to the / •))) position. 3. Touch the test probes to the diode under test. Forward voltage will indicate 400 to 700mV. Reverse voltage will indicate “I”. Shorted devices will indicate near 0mV. Shorted devices will indicate near 0mV and an open device will indicate “I” in both polarities. BATTERY TEST 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 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. KEEP THE METER DRY. If it gets wet, wipe it off. 2. USE AND STORE THE METER IN NORMAL TEMPERATURES.
REPLACING THE 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, “BAT” will appear in the right-hand side of 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 batteries are 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.
