Safety requirements

The following general safety precautions must be taken at any stage of operating the instrument. Failure to take

these safety precautions or to follow the warnings and precautions described elsewhere in this manual will violate

the safety standards for the design, manufacture, and use of the instrument. China Electronics Technology

Instruments Co., Ltd assumes no responsibility for the consequences arising from users’violation of these

requirements.

Use environment

For the working environment and storage environment of this instrument, please refer to the description of the

technical parameters in Chapter XI.

Power supply

For the requirements of the working power of this instrument, please refer to the description of the technical

parameters in Chapter XI. The working power of this instrument must range from 198Vac to 242Vac. Be sure to

use the dedicated three-wire power cord shipped with the instrument or the three-wire power cord of the regular

manufacturer's specifications, and ensure that the grounding is good, so as to avoid inducting voltage generated by

the enclosure. The fuse of the same specification shall be used when replacing the fuse in the fuse holder.

Do not use the instrument in an explosive or flammable environment

Do not use the instrument in the presence of flammable gases or fumes.

Do not disassemble any parts of the instrument

Do not disassemble any parts of the instrument except those that are authorized to be replaced by the users.

Replacement of parts and internal adjustments can only be carried out by the maintenance personnel authorized by

or entrusted by China Electronics Technology Instruments Co., Ltd.

Safety terms used in this manual

: Remind users to pay attention to a process, operation method, or similar situation. Failure to

operate properly or in accordance with the rules may result in personal injury or damage to the

instrument.

: Remind users to pay attention to a process, operation method, or similar situation. Failure to

operate properly or in accordance with the rules may result in partial or whole damage to the

instrument.

: Information that aids in the use and maintenance of the instrument.

Warning!

Caution!

Note!

Warnings for the use of instrument

Requirements for power supply

: The power supply used in this instrument must meet the following requirements: 220VAC ±

10%, 1.5A, 50 ~ 60Hz. Using a power supply that is too high/low or unstable will cause damage

to the instrument. Using a power supply that is too high/low or unstable will cause damage to

the instrument.

Laser safety

The safety standards for the lasers used in this instrument are in accordance with IEC65 and IEC348.

Although the output intensity of the laser used in this instrument is within the safety standard, it

may damage the visual acuity, so the output of the laser should be prevented from directly

shooting into the eye. Do not look directly into the light output connector of the instrument with

your eyes, and do not look directly at the end of the fiber during testing. When the VFL function

of the instrument is turned on, do not look directly at the VFL's output port or the end of the

fiber connected to the VFL output port.

Use of distributed optical fiber strain tester (BOTDR)

(1) It is absolutely not allowed to connect an optical fiber with any optical signal to the test port

of the 6419 distributed optical fiber strain tester. This may result in inaccurate measurement

results and even permanent damage to the instrument. Please ensure that all fibers tested by this

instrument are in a no-signal state.

(2) It is absolutely not allowed to connect and disconnect the optical fiber during the test of the

6419 distributed optical fiber strain tester. This will cause the instantaneous increase of echo of

the optical fiber tested by the instrument, which may cause permanent damage to the instrument.

(3) It is absolutely not allowed to connect the fiber interface that does not match the optical

interface of the 6419 distributed optical fiber strain tester to the test port of the 6419 distributed

optical fiber strain tester. This will not only increase the insertion loss due to the mismatched

optical interface and result in no inaccurate test results, but will also cause permanent damage to

the optical interface.

Transportation and packaging

(1) Please pack the 6419 distributed optical fiber strain tester with the original standard

aluminum alloy box during transportation, and ensure that the 6419 distributed optical fiber

strain tester does not move in the aluminum alloy box. Special note: When placing the

instrument in an aluminum alloy box, no filler is allowed in front of the LCD display to

avoid damage to the LCD display during transportation.

(2) Care should be taken during transportation to avoid damage to the 6419 distributed optical

fiber strain tester caused by severe shock and vibration.

Warning!

Notes for the use of instrument

LCD display

(1) Do not use a sharp object to click on the LCD screen, and do not impact the LCD screen

with big power. This will damage the LCD screen.

(2) Do not drop or splash organic solvents or contaminants on the LCD screen, such as acetone,

oil, antifreeze, grease, etc., otherwise the LCD screen will not work properly.

(3) Wipe the LCD screen with silk cloth or soft fabric. Do not wipe the LCD screen with organic

solvent, otherwise, this may damage the LCD screen.

Use of distributed optical fiber strain tester (BOTDR)

(1) The light output connector of the instrument has a delicate and fragile ceramic positioning

core inside. When the fiber is connected, be sure to insert the fiber plug in parallel and screw it

tightly after aligning the positioning pin.

(2) When using this instrument for measurement, the inside of the light output connector of the

instrument and the end face of the light output connector of the instrument must be kept clean to

prevent the grease and other contaminants from contaminating the light output connector.

Otherwise, it will cause measurement error of the instrument, and may cause the instrument not

be able to test the fiber.

(3) If possible, when testing the instrument, point the end of the fiber under test to a non-

reflective object.

Maintenance and service

(1) Please use the original packaging materials when carrying the instrument to avoid severe

shock and vibration.

(2) The instrument should be stored under the ambient temperature range between 0°C and 50°C,

and it should be kept ventilated and dried without direct sunlight.

(3) When storing the instrument, the dust cover on each optical port of the instrument should be

covered.
