• • • • • • • • • • DO NOT apply more than the rated voltage, as marked on the meter, between terminals or between any terminal and earth ground. Use caution when working above 30V AC rms, 42 V peak, or 60 V DC. Such voltages pose a shock hazard. To avoid false readings that could lead to possible electric shock or personal injury, replace the batteries as soon as the low battery indicator displays. Always inspect the multimeter, test leads and any other accessories for damage prior to every use.

be switched during a test, ALWAYS remove the test leads from the circuit being measured before switching settings. • To avoid possible electric shock, instrument damage, and/or equipment damage when taking voltage or current measurements, DO NOT exceed the maximum value of the selected range. • If the unit is used near high noise Radio Frequency (RF) generating equipment (spark plug wires, ignition coils or alternator), the display may become unstable or indicate large errors.
Ω" jack of the multimeter; 1. Plug the RED test lead into the "Ω plug the BLACK test lead into the "COM" jack. Ω" 2. Set the meter’s Function/Range Selector Switch to the "Ω range function (see Controls and Indicators, Item 3). NOTE: To obtain accurate readings, disconnect at least one side of the item under test from the circuit or circuit board before measuring resistance. 3. Place the RED test lead onto one side of the item being tested and the BLACK test lead onto the other side of the item.
D. CONTINUITY TEST WARNING To avoid electric shock, shut off the power to the test article before testing it for continuity. 1. Plug the RED test lead into the jack of the multimeter; plug the BLACK test lead into the "COM" jack. 2. Set the meter’s Function/Range Selector Switch to the position (see Controls and Indicators, Item 6). 3. Place the RED Test Lead to one end of the wire or device being tested for continuity and the BLACK Test Lead to the opposite end. 4.
NOTE: To measure current on a particular circuit, you must open up the circuit and connect the test leads in series with the circuit before a reading can be obtained. 4. Disconnect one end of the wire or device, from the circuit where current will be measured. 5. Place the RED test lead on the disconnected wire and place the BLACK test lead at the location from which the wire was disconnected (series connection). 6. Reconnect the battery, or apply power to the circuit being tested. 7.
BATTERY AND FUSE REPLACEMENT WARNING When replacing the battery or the fuse, remove only the rear panel. Do not remove or disassemble the circuit board or the front panel, these items are not serviceable and if disassembled there is the possibility of loose metal parts shorting the circuit board and causing an electrocution danger to the user. 1. Turn the Digital Multimeter “OFF” and remove the test leads. 2. Remove the two screws on the back of the meter and separate the case. 3.
SERVICE PROCEDURES The Manufacturer warrants to the original purchaser that this unit is free of defects in materials and workmanship under normal use and maintenance for a period of one (1) year from the date of original purchase. If the unit fails within the one (1) year period, it will be repaired or replaced, at the Manufacturer's option, at no charge, when returned prepaid to the Technical Service Center with Proof of Purchase. The sales receipt may be used for this purpose.
