Note: Input Jacks for test probes are a firm fit to prevent dislocation.
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. DC VOLTAGE MEASUREMENTS CAUTION: Do not measure DC voltages if a motor on the circuit is being switched ON or OFF.
DC CURRENT MEASUREMENTS CAUTION: Do not make 20A current measurements 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 6000µA DC, set the function switch to the yellow µA position and insert the red test lead banana plug into the µA/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 Ω CAP 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 “ 4. Touch the test probe tips across the circuit or part under test.
TEMPERATURE MEASUREMENTS 1. Set the function switch to the 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 ºF or ºC 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.
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: 1. Press the RANGE key. The “AUTO” display indicator will turn off. 2. Press the RANGE key to step through the available ranges until you select the range you want. 3.
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 covers. WARNING: To avoid electric shock, do not operate your meter until the battery and fuse covers 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 FUSES WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the fuse cover. 1. Disconnect the test leads from the meter. 2. Remove the protective rubber holster. 3. Remove the battery cover (two “B” screws) and the battery. 4. Remove the six “A” screws securing the rear cover. 5. Gently remove the old fuse and install the new fuse into the holder. 6. Always use a fuse of the proper size and value (0.
