COMPLIANCE
FDA-CDRH Compliance
Under the US Food and Drug Administration (FDA) Center for Devices and Radiological Health (CDRH), the
unit complies with the Code of Federal Regulations (CFR), Title 21, Subchapter J, which pertains to laser
safety and labeling. See following link for more information:
•http://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/CFRSearch.cfm?CFRPartFrom=1000&C
FRPartTo=1050
CSA / IEC Compliance
The unit complies with certain standards of the Canadian Standards Association (CSA) and the
International Electrotechnical Commission (IEC).
The unit falls in the Installation Category (Overvoltage Category) II under IEC 664. IEC 664 relates to
impulse voltage levels and insulation coordination. The category is defined as: local level, appliances,
portable equipment, etc., with smaller transient overvoltages than Installation Category (Overvoltage
Category) III.
The unit falls in the Pollution Degree 2 category under IEC 1010-1 and CAN/CSA-C22.2 No. 1010.1. The IEC
standard on Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use
relates to insulation coordination. The CSA standard is on Safety Requirements for Electrical Equipment

SAFETY INFORMATION
To avoid situations that could result in serious injuries or death, always observe the following precautions.
The safety instructions must be observed whenever the unit is operated, serviced, or repaired. Failure to
comply with any of these instructions or with any precaution or warning contained in the user manual is
in direct violation of the standards of design, manufacturing, and intended use of the unit. JGR Optics Inc.
assumes no liability for the customer’s failure to comply with any of these safety requirements.
Safety Markings on the Unit
See Table 1 for symbols and messages that can be marked on the unit. Observe all safety instructions that
are associated with a symbol.
Table 1: Safety symbols
Laser radiation may be present. Refer to the user manual for instructions on handling
and operating the unit safely. Avoid looking into any ports near which this symbol
appears.
Frame or chassis terminal for electrical grounding within the unit.
Protective conductor terminal for electrical grounding to the earth.
WARNING
Procedure can result in serious injury or loss of life if not carried out in proper
compliance with all safety instructions. Ensure that all conditions necessary for safe
handling and operation are met before proceeding.
CAUTION
Procedure can result in serious damage to or destruction of the unit if not carried out
in compliance with all instructions for proper use. Ensure that all conditions necessary
for safe handling and operation are met before proceeding.
Classification
The PT1 consists of an exposed metal chassis that is connected directly to earth via a power cord and is
therefore classified as a Class 1 instrument.
The laser (or lasers) contained in the PT1 is (are) Class 2 laser(s) as specified under the laser classification
of the US Food and Drug Administration (FDA) Center for Devices and Radiological Health (CDRH). See
Table 2 for laser specifications.

Important Safety Information
Laser Hazards
Warning
•Never look directly into the end of an optical cable connected to an optical
output device that is operating. Laser radiation is invisible and direct
exposure can severely injure the human eye.
Electrical Hazards
Warning
•Some of the circuits are powered whenever the unit is connected to the AC
power source (line power). To ensure that all circuits are powered off,
disconnect the power cord from either the power inlet on the unit’s rear
panel or from the AC line-power source (receptacle). The power cord must
always be accessible from one of these points. If the unit is installed in a
cabinet, the operator must be able to disconnect the unit from the line power
by the system’s line-power switch.
•Use only the type of power cord supplied with the unit. If you need to replace
a lost or damaged cord, make sure to replace with a power cord of the same
type.
•Connect the power cord only to a power outlet equipped with a protective
earth contact. Never connect to an extension cord or any receptacle that is
not equipped with this feature.
•If using a voltage-reducing autotransformer to power the unit, ensure that
the common terminal connects to the earthed pole of the power source.

•Do not interrupt the protective earth grounding. Such action can lead to a
potential shock hazard that can result in serious personal injury. Do not
operate the unit if an interruption to the protective grounding is suspected.
•Do not operate the unit when its cover or panels have been removed.
•To prevent potential fire or shock hazard, do not expose the unit to any source
of excessive moisture.
•Do not use the unit outdoor.
•Operating the unit in the presence of flammable gases or fumes is extremely
hazardous.
•If the equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired. Only technicians
authorized by JGR Optics Inc. should carry out repairs. In addition to voiding
the warranty, opening the unit (even when unplugged) can expose you to
potential shock hazards.
•Some of the unit’s capacitors can be charged even when the unit is not
connected to the power source.
•Do not perform any operating or maintenance procedure that is not
described in the user manual.

GETTING STARTED
Caution
•To avoid injury or death, always observe the precautions listed in SAFETY
INFORMATION on page 4.
This manual contains complete operating instructions for safe and effective operation of the PT1 Polarity
Tester. It is recommended that users of the PT1 familiarize themselves with contents of this manual
before using the instrument.
The inspection report and a description of any customer-requested information may be found in the
calibration document envelope included with the instrument.
Initial Inspection
Warning
•To avoid electrical shock, do not initialize or operate the unit if it bears any
sign of damage. Ensure that the unit and any devices or cords connected to it
are properly grounded.
✓Inspect the package and contents for signs of damage.
✓Ensure all contents are included.
✓Read the user manual thoroughly and become familiar with all safety symbols and instructions to
ensure that the unit is operated and maintained safely.
✓If the initial inspection reveals any damage or missing components, immediately notify JGR Optics
Inc. and if necessary, the carrier.
Operational Requirements
For the unit to meet the warranted specifications, the operating environment must meet the conditions
outlined in Table 3.

Product Overview
PT1 Front Panel
A front view of the PT1 meter is shown in Figure 2. It features a touchscreen which displays information
such as results, VFL, test plans and setup.
The MTP/MPO output and receive panel is located on the front of the unit. The connectors are 12 fiber
MTP/APC male (SM) for the output and 12 fiber MTP/PC male (MM) for the receive. This allows the PT1
to test both SM and MM assemblies.
When testing assemblies with more than 12 fibers, fanout cables are required to connect from the PT1
output/receive to the DUT (Figure 10).

Notes:
•By using SM output and MM receive cables, the DUT can be either SM or MM. The PT1 can
accurately measure polarity as long as the direction of light is going from a core of size d1to a core
of size d2where d1≤ d2
•The non-contact adapters (NCA) are ideal for high volume testing as they negate the risk of
contamination or damage during mating. No connector end-face inspection is required. The NCA
should be used between the output/receive cables and the DUT.
•When testing DUTs with more than 12 fibers, fanouts are required for the output and receive
cables. For an example, see Figure 10.
