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.
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.
AC VOLTAGE MEASUREMENTS AC VOLTAGE: 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 20A 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 WARNING: To avoid electric shock, do not attempt to measure AC A in circuits that have voltages which exceed 250V AC. CAUTION: Do not make current measurements on the 20A scale for longer than 30 seconds. Exceeding 30 seconds may cause damage to the meter and/or the test leads.
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 position. 2. Insert the black test lead banana plug into the negative (COM) jack Insert the red test lead banana plug into the positive...
CONTINUITY CHECK WARNING: To avoid electric shock, never measure continuity on circuits or wires that have voltage on them. 1. Set the function switch to the position. 2. Insert the black lead banana plug into the negative (COM) jack Insert the red test lead banana plug into the positive ( ) jack.
CONTACT TEMPERATURE MEASUREMENTS 1. Set the function switch to the (K) ºF or ºC position. 2. Insert the Temperature Probe into the input jacks, making sure to observe the correct polarity. 3. Touch the Temperature Probe head to the part whose temperature you wish to measure.
NON-CONTACT TEMPERATURE MEASUREMENTS 1. Set the function switch to the Non-Contact (IR) ºF or ºC position. 2. Point the meter at the surface to be measured. 3. If needed, press the red IR Laser Pointer button to locate the exact spot being measured. 4.
CAPACITANCE MEASUREMENTS WARNING: To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any capacitance measurements. Remove the batteries and unplug the line cords. 1. Set the function switch to the CAP position. 2.
FREQUENCY MEASUREMENTS Set the function switch to the “FREQ %” position. Insert the black lead banana plug into the negative COM jack and the red test lead banana plug into the positive Hz jack. Touch the test probe tips to the circuit under test.
AUTORANGE/MANUAL RANGE SELECTION When the meter is first turned on, it automatically goes into AutoRanging. 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.
DATA HOLD The hold function freezes the reading in the display. Press the HOLD key momentarily to activate or to exit the hold function. Note: In the Frequency mode, Data Hold will function only while a frequency is applied. AUTO POWER OFF The auto off feature will turn the meter off after 20 minutes.
MAINTENANCE WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the back cover or the battery cover. WARNING: To avoid electric shock, do not operate your meter until the battery 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.
BATTERY REPLACEMENT WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the battery cover. 1. When the battery becomes exhausted or drops below the operating voltage, “ ” will appear in the left-hand side of the LCD display.
FUSE REPLACEMENT 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 protective rubber holster. 3. Remove the battery cover (two “B” screws). 4.
