E. Low Battery LED:
LED illuminates when the battery
needs to be replaced.
F. 6 Foot Coiled Cord:
Insulation black colour 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 coiled cord’s banana plug end to known
ground. Use adapters where needed. NOTE: The
Vermason Low Resistance Tester may be used with
an outlet polarity checker such as the Vermason
222606
or
222607
to determine a known ground.
3. Connect or touch the tester end to a banana jack,
common ground point, earth bonding point 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 LED does not illuminate.
Example of Test Range Uses
<1 OHM Range
- ESD Technical element Grounding Conductors:
Banana Jacks, Common Ground Points, Earth Bonding
Points, Grounding Blocks, Mat Ground Cords
ANSI/ESD S6.1 Grounding, sections 6.4 Technical
Elements,
6.4.1, 6.4.2 and 6.4.3
- New AC Powered Hand Tools
ESD Handbook ESD TR20.20 section 5.5.2.2 Electrical
Hand Tools
<2 OHM
- Soldering Irons
ESD Handbook ESD TR20.20 section 5.5.2.2 Electrical
Hand Tools
- Other AC Powered Hand Tools
ESD Handbook ESD TR20.20 section 5.5.2.2 Electrical
Hand Tools
<20 OHM
- Soldering iron compliance verification
ESD Handbook ESD TR20.20 section 5.5.2.2 Electrical
Hand Tools
- Functional auxiliary grounds (ground rods)
ANSI/ESD S20.20*
* ANSI/ESD S20.20 requires <25 ohms from the Auxiliary
Ground to the Equipment Grounding Conductor. Vermason’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 Functional Ground, an Ohmmeter should used to
determine the actual resistance from the Auxiliary Functional
Ground to Protective Earth Ground
