Elenco Digital Multimeter - Manual (Page 13)

Note: Open-circuit voltage between measuring terminals is
approximately 1.5V (measuring current approximately 1.5mA).
Testing for Continuity
Caution
To avoid possible damage to the meter or to the equipment
under test, disconnect the circuit power and discharge all
high-voltage capacitors before testing for continuity.
Continuity is the presence of a complete path for current flow. The
continuity test features a beeper that sounds if a circuit is complete
(the resistance less than 120
Ω approx.). The beeper allows you to
perform quick continuity tests without having to watch the display.
The continuity function detects intermittent opens and shorts lasting
as little as 1 millisecond (0.001 second). These brief contacts cause
the meter to emit a short beep. Refer to Figure 12 for continuity
testing setup instructions.

Measuring DC Voltage
1. Turn on the meter, then set up the meter to measure DC volts as
shown in Figure 6.
2. Insert the black test lead into the COM terminal and the red test
lead into the terminal.
3. Set the Function Rotary Switch to the ~V position (then, “AUTO”
and “mV” symbols are indicated on the display).
4. Connect the black test lead to the negative side of the circuit
under test and the red test lead to the positive side of the
circuit.The measured value is indicated on the display. If you
connect the test leads to the opposite polarity, the “–” symbol
appears on the display.
