Ac Current Measurement; Capacitance Measurement (Acd-23Sw Only); Resistance - Amprobe ACD-22SW Mode D'emploi

4. Read the voltage on the primary display and the frequency on the
secondary display. If necessary, correct any overload (OL) conditions.

AC Current Measurement

1. Set the Function Switch to position ?.
2. Open spring-loaded clamp by pressing the jaw opening lever on the left
side of meter.
3. Position clamp around one wire or conductor. Release the jaw opening
lever. Wire should be center inside the jaws. Refer to Fig.3
4. Read the current on the primary display and the frequency on the
secondary display. If necessary, correct any overload (OL) conditions.

Capacitance Measurement (ACD-23SW 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 (OL) conditions.
CAUTION
W
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.

Resistance

1. Set the Function Selector knob Switch to e (ACD-22SW) or e / R (ACD-
23SW) to select the resistance test. Use the Auxiliary features push button
(°F/°C/R/e) to select resistance (ACD-23SW)
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 OL appears on the highest Range, the resistance is too
large to be measured or the circuit is an open circuit.
