Current Measurement; Resistance Measurement - Lutron Electronics DM-9030 User Manual

5-2 Current Measurement

1) Connect red test lead to "10A" input terminal and black
test lead to " COM " input terminal.
2) A. If current to be measured is AC, select " AC/DC
Switch " to the " AC " position.
B. If current to be measured is DC, select " AC/DC
Switch " to the " DC " position.
3) Select the " Function Switch " to the " 10 A " position.
4) Open the circuit in which current is to be measured. Now
securely connect test leads in series with the load in which
the current is be measured.

5-3 Resistance Measurement

1) Connect red test lead to " OHM " input terminal and black
test lead to " COM " input terminal.
2) Determine the highest anticipated resistance ( 200OHM,
2K, 20K, 200K , 2000K or 20 M ( K = 1000)) on the
" function switch " and select to the corresponding position.
3) If the resistance being measured is connected to a circuit,
turn off power to circuit being tested and discharge all
capacitors.
4) Connect test lead probes into circuit ( resistance ) under test.
5) Read resistance value on digital display.
6) APPLICATION 1 : " 2K, 200K RANGE " to measure the
coil's resistance.
7) APPLICATION 2 : " 2M RANGE" to measure whether
the " CAPACITOR " is good or not.
