• Detects probable improper wiring conditions in 110-125VAC
• Consult the GFCI manufacturer's installation instructions to determine that
  the GFCI is installed in accordance with the manufacturer's specifications.
• Check for correct wiring of receptacle and all remotely connected
  receptacles on the branch circuit.
• Detect faulty wiring in 3 wire receptacle.
• Test for GFCI receptacle for proper operation, 110-125V circuits.
• INPUT VOLTAGE: 120V ± 10%.
• OPERATING TEMPERATURE: 5-40°C (41-104°F).
• STORAGE TEMPERATURE: -20-60°C (-4-140°F)
• OPERATING HUMIDITY: Max 80% with temperature up to 30°C (86°F);
  linearly decreasing to 50% at temperature 40°C (104°F)
• STORAGE HUMIDITY <80%
• ALTITUDE <2000m (7000ft)
• SIZE 108mm x 45mm x 28mm.
• To avoid erroneous readings, unplug any appliances or equipment
  on the circuit being tested.
• Various combinations of three lights tell if wiring is correct or six
  possible faulty conditions.
• With UL and cUL Approval.
• Patented.
