reading. If the meter reading minus the probe resistance is less than 0.1 ohms, the two points have electrical
continuity.
RESISTANCE
To measure the resistance between two points.
1. Set your meter to measure resistance (usually labeled with the ohm symbol).
2. Hold the two probes apart from each other in the air. The meter must indicate infinite resistance (usually indicated
by the infinity symbol or on digital multimeters, "++++" or "0L" for overload).
3. Hold the two probes together. The meter must indicate a very low resistance, less than 1.0 ohms. The resistance
measured will vary depending on what scale the meter is set to
4. If the expected resistance is less than 20.0 ohms ohms, go to 6.
5. Place one probe on one point and the other probe on the other point. It does not matter which probe is placed on
which point when measuring resistance. Read the resistance indicated in the meter
6. Since we are expecting to measure a resistance less than 20.0 ohms, set the meter to an appropriate scale, likely
the lowest available.
7. Hold the two probes together. The meter must indicate a very low resistance, less than 1.0 ohms. Record or
memorize this resistance. This is the probe resistance.
8. Place one probe on one point and the other probe on the other point. It does not matter which probe is placed
on which point when measuring resistance. Subtract the probe resistance measured in 7 above from the meter
reading. The meter reading minus the probe resistance is the resistance between the two points.
