6. Safety information
The PM 215 instrument emits no optical power itself and does not create any hazards
to the user. WARNING!
•Never use magnifying devices to inspect optical fiber ends unless you are sure
that no optical power is being emitted.
•Use only magnifying devices with a built-in infra-red filter to ensure safety.
•During operation, testing or maintenance of a fiber optic system, never look into
an active fiber optic cable. Infrared radiation may be present and permanent eye
damage can result.
•Avoid direct exposure to the beam.
•Do not activate the laser when there is no fiber attached to the optical output
connector
Under no circumstances should you look into the end of an optical cable attached to
the optical output when the device is operational. Laser radiation can seriously
damage your eyesight.
7. Maintenance
7.1 Battery care
The PM 215 comes equipped with a built-in charger and internal battery pack.
•Before using the PM 215 for first time, charge fully battery pack.
•Use the USB charger, cable and USB port for charging.
•Charging is not recommended until battery status is 30% or less.
Recommended charging time of battery pack is 4 to 7 hrs.
•We don’t recommended charge the battery pack fully before storing PM 215
(optimal value is about 70 %).
•If you are not going to use the PM 215 for long period, charge the battery
pack once every six months.

PM-215 –GL INSTRUCTION MANUAL

•The battery pack is a consumable. Repeated charging and discharging
degreases battery pack life. Please contact OPTOKON for battery pack
replacement.
•Battery status informs about current energy of battery. In case PM-215 has
fully battery charged, is displayed this char „“(figure 2).
Figure 1: Battery status
Figure 2: Status of fully chargered battery
7.2 Instrument care
•During storage and transport keep the instrument in its carry case to protect
against crushing, vibration, dust and moisture.
•Where possible keep the instrument away from strong sunlight.
•Clean the instrument housing using alcohol or other cleaning agents. Acetone or
other active solvents may damage the case.
•The instrument is resistant to normal dust and moisture, however it is not
waterproof. If moisture does get into instrument, dry it out carefully before
using it again.
7.3 Optical connector care
•Cleanliness will affect the performance of an optical fiber system.
•All connectors and fiber end faces need to be clean prior to testing.
•Clean all connectors, adapters, and attenuators before making any connections.
•Use appropriate optical cleaning supplies to keep connectors and adaptors free
from contamination.
•The following cleaning materials are recommended and can form part of your
cleaning kit:
- Lint-free laboratory wipes.
- Isopropyl alcohol in pressurised dispenser
- Lint free pipe cleaners
- Clean, dry, oil-free compressed air

9. Working with the internal memory
The PM 215 memory has a structured,
two-
level organization. The results are
stored in memory positions (MEM) in
folders called Cable (CAB). See the table:
A maximum of 100 results can be stored
in the memory, although the maximum
number of CAB and MEM is 100. This
means, if 50 CAB folders are used, each
CAB folder can contain a maximum of
two memory positions (MEM), a
nd vice
versa; if only two CAB folders are used,
each folder can contain up to 50 memory
positions (MEM).

10. Insertion Loss Measurement
10.1 Basic theory
Loss measures the signal degradation in a fiber optic cable. A light source injects an
optical signal of the appropriate wavelength into the fiber and a power meter
measures the received signal at the same wavelength.
There are two different measurement methods:
•Method 6
•Method 7
according to IEC 874-1 4.4.7.4.
Power measurement is the basis of optical testing and determines the power budget
of the fiber optic link by comparing the power of the transmitter and the sensitivity of
the receiver. This difference is the maximum acceptable loss. Power loss is caused by

PM-215 –GL INSTRUCTION MANUAL
16
different phenomena such as attenuation of the fiber, dirty connector mating faces,
connector misalignment, loss of splices and other issues such as sharp fiber bends.
The "end to end" loss test is the most commonly used acceptance test for power loss
in fiber optic links. The test is based on measurement the power difference at the
input and output of the link.
The PM 215 and LS-800/LS-215 are used for this test, where the light source (LS-
800/LS-215) acts as a transmitter and the optical power meter (PM 215) as a
receiver.
The "end to end" test includes two steps:
1. Setting the reference
2. Measurement the loss
10.2 Method 6
For method 6 two master cords are used to set the reference. Method 6 cancels the
effects of the master cords and one adaptor for all subsequent measurements.
10.2.1 Setting the reference
1. Connect the first master cord to the power meter (PM-215).
2. Connect the second master cord to the light source (LS-800/LS-215).
3. Use the master adaptor to connect the two fiber ends (figure 15).
4. Power on the light source and by pushing [
λ
].select the appropriate wavelength.
5. Power on the power meter and by pushing [
λ
] select the appropriate wavelength
range.
6. On the power meter activate the relative power measurement mode - by pushing
[REL].
7. Set and store the new reference for the selected wavelength - push [REF],
[CONFIRM].
Figure 14: Setting reference by method 6

PM-215 –GL INSTRUCTION MANUAL

10.2.2 Measurement Loss
1. Do not disconnect the master cords from the light source and the power meter.
2. Disconnect one master cord from the adaptor.
3. Connect the trace to be measured between the master cords. An extra master
adaptor is required (fig.16).
4. The power meter display will report the loss in dB.
Figure 15: Measurement Loss by method 6
10.3 Method 7
For method 7, one master cord is used to set the reference. The master cord will be
cancelled for all subsequent measurements.
10.3.1 Setting the reference
1. Connect the master cord to the power meter (PM 215).
2. Connect the second end of the master cord to the light source (LS-800/LS-215).
3. Power on the light source and select the appropriate wavelength - by pushing
[
λ
].
4. Power on the power meter and select the appropriate wavelength range - by
pushing [
λ
].
5. On the power meter activate the relative power measurement mode - by pushing
[REL].
6. Set and store the new reference for the selected wavelength - push [REF],
[CONFIRM].
