Test Equipment/Forms Required
The following are required to perform the safety tests:
• Fluke 1507 - Insulation Tester, or
• Low Impedance or Bonding Meter capable of supplying 200 mA into 500 milliohm (open
circuit voltage <24 V)
• Megaohm Meter capable of measurements at 250 V or 500 V (for Insulation Resistance test)
• Fluke 360 - Leakage Current Clamp Meter
• Test Results Form or equivalent
Procedures
NOTE:
• The following procedures assume that the recommended test equipment is used. If you use
different test equipment, you will have to adjust the procedure based on the equipment used.
• Tests must to be performed at the ambient temperature, humidity, atmospheric pressure and
mains voltage present at the test site.
Visual Inspection
Perform a visual inspection of system and accessories to include:
• Safety-related markings and labeling are legible and complete
• Integrity of mechanical parts
• Absence of any damage or contamination
• Required documentation is present and reflects the current revision and configuration of the
system
Protective Earth Resistance
Purpose: Measures the protective earth resistance between the ground terminal of the scanner power
cord and grounded metal parts on the scanner.
Test Equipment: Fluke 1507 - Insulation Tester
Acceptable Value: Less than 3 ohms.
1. Power off scanner and disconnect scanner power cord from wall outlet. If retention bracket is
installed over power cord, remove bracket so power cord can be disconnected from outlet.
2. Remove cover from receptor assembly.
