Auto Power Off (APO)

The Auto Power Off (APO) feature will set the meter to sleep mode after approximately 30

minutes of no activity to extend battery life. Wake up the meter from APO, by set the slide-

switch to the OFF and back to the desired function.

HOLD � function

The HOLD button enables/disables the reading HOLD function. After the reading has

stabilized, momentarily press the HOLD button. You can remove the test leads and the

reading will remain on the display.

The ∆ button enables/disables relative mode. Relative mode offsets the subsequent meter

measurements with the displayed reading as a reference value. The display will now show

readings relative to the stored reference value. That is, display = measured reading - stored

value.

1. Set the Function Switch to V�.

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

3. Connect the test probes to the circuit test points.

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

1. Set the Function Switch to V�.

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

3. Connect the test probes to the circuit test points.

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

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.

4. Read the displayed value.

� CAUTION

Using Resistance, Continuity or Diode 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 measurement reading.

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. 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.
