Quick-Check Wiring Test Procedures

To quickly check a Wire for Resistance we recommend the following:

Audible Continuity

An Audible Continuity feature allows the operator to do a quick resistance test

without looking at the display panel.

 

WARNING:

The circuit being tested MUST be OFF with

NO VOLTAGE PRESENT!

After verifying that the circuit under test is completely OFF and no voltage is present -          

Use the DC/AC test capability of the Meter to make that verification:

 

1. Set meter to Audible Continuity test.

2. Connect test leads to circuit being tested.

3. If resistance is under a predetermined amount (may vary from meter to meter, typically under 100 ohms) the Audible Tone will sound, confirming Continuity. 

Testing a Circuit or Wire for Resistance

Measuring OHMS ""

 A Meter:

1. Sends a voltage from its own power (battery) into the connected circuit.

2. Measures exactly how much the voltage is reduced by resistance in the circuit under test.

3. Then calculates and displays the OHMS of resistance in the circuit.

WARNING:

The circuit being tested MUST be OFF with

NO VOLTAGE PRESENT!

After verifying that the circuit under test is completely OFF and no voltage is present -        

Use the DC/AC test capability of the Meter to make that verification:

 

1.    Turn the rotary function switch to the "" position to measure resistance.

2.    Connect the test leads across the circuit or wire to be tested.

3a.  Some meters have an “autorange” feature which will determine the most         

       appropriate scale for OHMS display -

       "" (OHMS),

       "K" (Thousands of OHMS),

       "M" (Millions of OHMS).

3b.   The operator can manually select the scale by pressing the "RANGE" button.
