Capacitance Measurement (ACD-21SW / ACD-21SWC only)

When testing a capacitor that is part of a circuit, if "dS.C" is displayed on the

screen, a voltage is present. Discharge the capacitor before testing.

1. Sett the Function Switch to " E " position.

2. Connect the test leads: Red to +, Black to COM.

3. Connect the test probes to the circuit test points. Refer to Fig. 4

4. Read the display. If necessary, correct any overload (0L) conditions.

CAUTION

Using the Resistance or Continuity function in a live circuit will produce false

results and may damage the instrument. In most cases the suspected component

must be disconnected from the circuit to obtain an accurate reading.

1. Set the Function Switch to e. Use the "e/R" button to select the

resistance test (ACD-21SW / ACD-21SWC only).

2. Connect the test leads: Red to +, Black to COM.

3. Turn off power to the circuit being measured. Never measure resistance

across a voltage source or on a powered circuit.

4. Discharge any capacitors that may influence the reading.

5. Connect the test probes across the resistance. Refer to Fig.5

6. Read the display. If 0L appears on the highest Range, the resistance is too

large to be measured or the circuit is an open circuit.

1. Set the Function Switch to e. Use the "e/R" button to select the test

(ACD-21SW / ACD-21SWC only).

2. Connect the test leads: Red to +, Black to COM.

3. Turn off power to the circuit being measured.

4. Discharge any capacitors that may influence the reading.

5. Connect the test probes across the resistance or the two points of test

6. Listen for the tone that indicates continuity (< 25e).
