E. Low Battery LED:
LED illuminates when the battery
needs to be replaced.
F. 6 Foot Coiled Cord:
Insulation black color PVC
G. Banana Plug:
Industrial Standard .175" (4.4 mm) Banana
Plug, fits banana jack ≥ .157".
Operation
USING THE TESTER
1. Use the slide switch to select a test range.
2. Connect the coil cord banana plug end to known ground.
Use adapters where needed. NOTE: The Desco Low
Resistance Tester may be used with an outlet polarity
checker such as the Desco 19219 to determine a known
ground.
3. Connect or touch the tester end to a banana jack or
other equipment that is being tested for resistance to
ground.
4. Press and hold the test button.
5. An audio and visual indication will activate for a PASS
condition.
6. A FAIL condition is indicated when the buzzer does not
sound and the PASS does not illuminate.

- Auxiliary grounds (ground rods)
ANSI/ESD S20.20*
* ANSI/ESD S20.20 requires <25 ohms from the Auxiliary
Ground to the Equipment Grounding Conductor. Desco’s
Low Resistance Tester only tests to <20 ohms. In cases
of a no pass result with the Low Resistance Tester when
testing an Auxiliary Ground, an Ohm meter should used to
determine the actual resistance from the Auxiliary Ground to
the Equipment Grounding Conductor
