Measuring AC Current - See Figure 3
1. Set the Function Switch to A position.
2. Open spring-loaded clamp by pressing the lever on left side of meter.
3. Position clamp around one wire or conductor and release the clamp lever. Make sure
that the clamp is entirely closed. The clamp must be positioned around only one con-
ductor. If it is placed around two or more current carrying conductors, the reading is
FALSE.
4. Read the displayed value, and if necessary, correct any overload (0L) conditions.
Measuring Frequency - See Figure 3
The Voltmeter detects the frequency of the voltage applied to the test leads.
1. Set-up AC voltage measurement and press the Hz button.
2. Read the frequency value on the display .
Using the Resistance, Continuity, Diode or Capacitance functions on a live circuit will
produce false results and may damage the instrument. In many cases the suspected
component must be disconnected from the circuit to obtain an accurate measurement
reading.
Measuring Resistance - See Figure 4
1. Set the Function Switch to Ω.
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.
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.
