AC Current (see fig. 2)
Set the function Switch to A 1. � position.
Select AC current using the SeleCT button. 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 4.
the clamp is entirely closed. The clamp must be positioned around only one conductor. if it
is placed around two or more current carrying conductors, the reading is fAlSe.
Read the displayed value, and if necessary, correct any overload (
5. 0L) conditions.
DC Current (see fig. 2)
Set the function Switch to A 1. � position.
Select DC current using the SeleCT button. 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 4.
the clamp is entirely closed. The clamp must be positioned around only one conductor. if it
is placed around two or more current carrying conductors, the reading is fAlSe.
Read the displayed value, and if necessary, correct any overload (
5. 0L) conditions.
CAUTIoN
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.
Resistance (see fig. 3)
Set the function Switch to 1. Ω.
Connect the test leads: Red to 2. +, Black to CoM.
Turn off power to the circuit being measured. 3.
Discharge any capacitors that may influence the reading. 4.
Connect the test probes across the resistance. 5.
Read the display. if 6. 0L appears on the highest range, the resistance is too large to be
measured or the circuit is an open circuit.
Continuity (see fig. 3)
Set the function Switch to 1. Ω and press the SeleCT button until � is displayed.
Connect the test leads: Red to 2. +, Black to CoM.
Turn off power to the circuit being measured. 3.
Discharge any capacitors that may influence the reading. 4.
Connect the test probes across the resistance or the two points of test. 5.
listen for the tone that indicates continuity (>10 6. Ω and < 120 Ω).
Diodes (see fig. 3)
Set the function Switch to 1. Ω and press the SeleCT button until � is displayed.
Connect the test leads: Red to 2. +, Black to CoM.
