Elenco 3 1/2 Digit with Temperature - Manual (Page 17)

Measuring DC Current
1. Turn off power to the circuit. Discharge all high-voltage
capacitors.
2. Turn on the meter, then set up the meter to measure DC current
as shown in Figure 8.
3. Insert the black test lead into the COM terminal and the red lead
into an input appropriate for the measurement range as shown
in Table 6.
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
so the meter is in series with the circuit.
5. Turn the on the power for the circuit under test.
6. The measured value is indicated on the display.
If you connect the test leads to the reverse polarities, a “–” symbol
will be shown on the display.
Note: To avoid blowing the meter’s 500mA fuse, use the mA
terminal only if you are sure the current is less than 400mA.
