voltage with respect to earth ground exceeds (in this case) 500 VAC or VDC. This symbol adjacent to one or more terminals identifies them as being associated with ranges that may, in normal use, be subjected to particularly hazardous voltages. For maximum safety, the meter and its test leads should not be handled when these terminals are energized. - Page 5 Function switch 10A jack COM jack Positive jack Data Hold Button Backlight Button Note: Tilt stand, fuse and battery compartment are on rear of unit.

random, changing reading. This is normal and is caused by the high-input sensitivity. The reading will stabilize and give a proper measurement when connected to a circuit. DC VOLTAGE MEASUREMENTS CAUTION: Do not measure DC voltages if a motor on the circuit is being switched ON or OFF. -
Page 11: Dc Current 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. - Page 12 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.

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. -
Page 15: Battery Test
BATTERY TEST Insert the black test lead banana plug into the negative COM jack and the red test lead banana plug into the positive V jack. Select the 1.5V or 9V BAT position using the function select switch. Connect the red test lead to the positive side of the 1.5V or 9V battery and the black test lead to the negative side of the 1.5V or 9V battery. -
Page 16: Replacing The Fuses
Follow instructions for installing batteries. See the Battery Installation section of this manual. Dispose of the old batteries properly. WARNING: To avoid electric shock, do not operate your meter until the battery door is in place and fastened securely. REPLACING THE FUSES WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before removing the fuse door. - Page 17 WARNING: To avoid electric shock, do not operate your meter until the fuse door is in place and fastened securely.
