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. 5—1. DC Voltage Measuments CAUTION: Do not measure DC voltages if a motor on the circuit is being switched ON or OFF. Large voltage surges may occur that can damage the meter. 1.Set the function switch to the green VDC position. 2.Insert the black test lead banana plug into the Negative COM jack. Insert the red test lead banana plug into the positive V jack. 3.Touch the black test probe tip to the negative side of the circuit. Touch the red test probe tip to the Positive side of The circuit. 4.Read the voltage in the display. ¢== 1| 1| |====0

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 voltagesif a motor on the circuit is being switched ON or OFF. Large voltage surges may occur that can damage the meter. 1.Set the function switch to the green VAG/Hz/% position. 2.Insert the black test lead banana plug into the Negative COM jack. Insert red test lead banana plug into the positive V jack. 3.Touch the black test probe tip to the neutral side of the circuit. Touch the red test probe tip to the "hot" side of the circuit. 4.Read the voltage in the display. 5.Press the HZ/% button to indicate "Hz". 6.Read the frequency in the display. 7.Press the Hz/% button again to indicate "%". 8.Read the % of duty cycle in the display.

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 green »» «4) 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.Press the MODE button to indicate "C2" on the display. 4.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. 5.Read the resistance in the display.

Continuty 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 green Q@ »» «4) position. 2.Insert the black lead banana plug into the negative COM jack. Insert the red test lead banana plug into the positive © jack. 3.Press the MODE button to indicate " «4) " and _ "O" on the display 4.Touch the test probe tips to the circuit or wire you wish to check. 5 .If the resistance is less than approximately 35C2, the audible signal will sound. If the circuit is open, the display will Indicate "OL" 5—7. Diode Test 1.Set the function switch to the green 2 » «4) position. 2.Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the positive V jack. 3.Press the MODE button to indicate » and V on the display. 4.Touch the test probes to the diode under test. Forward voltage will typically indicate 0.400 to 0.700V. Reverse voltage will indicate "OL". Shorted devices will indicate near OV and an open device will indicate "OL" in both Polarities.

TEMPERATURE MEASUREMENTS 1.Set the function switch to the green Temp position. 2.Insert the Temperature Probe into the input jacks, making sure to observe the correct polarity. 3.Press the MODE button to indicate °F or °C. 4.Touch the Temperature Probe head to the part whose temperature you wish to measure. Keep the probe touching the part under test until the reading stabilizes (about 30 seconds). 5.Read the temperature in the display. Note: The temperature probe is fitted with a type K mini connector. A mini connector to banana connector adaptor is supplied for connection to the input banana jJacks. 5—10. Autoranging/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:
