10 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. 3. Insert the...

11 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, th...

12 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. WARNING: To avoi...

15 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 ban...

17 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. Keep the probe touchi...

18 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. The area of the surface to be measured must ...

19 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. Insert the black test lead...

20 FREQUENCY MEASUREMENTS 1. Set the function switch to the “FREQ %” position. 2. Insert the black lead banana plug into the negative COM jack and the red test lead banana plug into the positive Hz jack. 3. Touch the test probe tips to the circuit under test. 4. Read the frequency on the display. % ...

22 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 min...

23 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 design...
