Resistance Limit Mode

The Tester has a resistance limit mode that allows you to set a maximum

resistance reading. If a resistance reading exceeds the set limit, the Tester

beeps and the >LIMIT icon displays. The limit can be set between 0 and

1999 Ω.

To set the maximum resistance:

1. Set the rotary switch to LIMIT. If the limit mode is on, the Tester

displays the stored limit setting. If the limit mode is off, the Tester

displays OFF.

2. If the limit mode is off, press START. The Tester displays the stored

limit setting.

3. Press DISPLAY to step through the digits to select the digit that you

want to set. The first press of DISPLAY selects the leftmost digit.

(The digit flashes when selected.) The second and third press of

DISPLAY selects the second and third digits. The fourth press of

DISPLAY selects the decimal point to set the resolution of the

measurement.

4. With the digit selected that you want to set, press START to

increment the value. The leftmost digit increments from 0 to 19. The

other digits increment from 0 to 9. Or if you selected the decimal

point, press START to move the decimal point to change the

resolution of the measurement.

5. Repeat steps 3 and 4 until you have set the maximum resistance

value. When you have finished, set the rotary switch to OFF for 5

seconds to store the value.
