Description
The Tempo Communications berTOOLS™ instruments are handheld
ber optic tools designed to measure optical power levels and link loss
on multi-mode and single-mode ber optic cabling networks.
• The OPM510 power meter measures optical power at 850 nm, 1300
nm, 1310 nm, 1490nm, 1550nm and 1625 nm between a power range of
+10 to -65dBm. The OPM510 is supplied standard with a SC bulkhead
adapter with LC, ST and FC adapters optionally available.
• The OPM520 power meter measures optical power at 850 nm, 1300
nm, 1310 nm, 1490nm, 1550nm and 1625 nm between a power range of
+27 to -50dBm. The OPM520 is supplied standard with a SC bulkhead

Important Safety Information

6
The SLS520, SLS530, SLLS535 and SLS5336 instruments are a laser
device conforming to the requirements of CDRH, CFR 1040. While there
is no potential for eye damage due to unaided direct exposure, users
should always avoid looking directly into the output port. The use of
optical viewing instruments, such as microscopes, magniers, etc.,
should always be avoided. The use of such devices around active bers
can focus an intense beam of light energy onto the retina of the eye,
which can result in permanent damage.
Laser hazard:
• When performing measurements on ber optic systems, avoid eye
exposure to any open-ended bers, optical connectors, optical
interfaces, or other sources because they may be connected to
active laser transmitters.
• Do not look into the optical port when a source is turned on.
• Avoid looking at the free end of a test ber, i.e., the end not con-
nected to the instrument. If possible, direct the free end toward a
non-reective surface.
Failure to observe these precautions may result in injury.

damage the unit.
Instrument damage hazard:
• Do not leave the unit in direct sunlight or near direct sources of
heat.
• Protect the unit from strong impacts or shock.
• Do not immerse the unit in water or store in areas with high
humidity.
• When necessary, clean the case, front panel, and rubber cover with
a damp cloth. Do not use abrasives, harsh chemicals, or solvents.
• Replace the interface dust cap(s) when the unit is not in use.
• Store the unit and interface adapters in a cool, dry, and clean place.
Failure to observe these precautions may result in injury and may
damage the unit.

General Information
This section provides general instructions on how to use the ber-
TOOLS instruments.
If circumstances require that the instruments be serviced and
maintained in-house, contact Tempo Communications for technical
assistance.
Battery
The OPM510, OPM520, SLS520, SLS525, SLS530, SLS535 and SLS536
instruments are powered by one 9V alkaline battery or one 9V Lithium
battery.
The external power supply can be used to power and charge all OPM
and SLS versions.
Do not attempt to charge alkaline batteries with the external power
supply.
When the battery power is low the low battery indicator will be dis-
played on the LCD.
Auto Power Off.
The instrument will automatically turn off if there are no keypad pushes
for approximately ve minutes.
To deactivate the auto power off hold the [On/Off] when turning on until
“AUTO OFF” is displayed on LCD. To reactivate the auto power off hold
the [On/Off] button until “AUTO OFF” is no longer displayed.

Battery Installation or Replacement
To replace the batteries, follow these steps:
1. Turn instrument off.
2. Remove battery cover by sliding down.
3. Install new battery to the wire leads observing correct polarity.
Connector Interface
All berTOOLS OPM and SLS units utilize a screw on adapter for SC,
LC, FC and ST congurations. The OPM and SLS instrument bulkheads
are unique in that the adapters for the OPM are different from the SLS.
Do not attempt to use a OPM adapter on a SLS or vice versa. Please
consult the accessories section of this instruction manual for adapter
part numbers.
Battery Installation or Replacement (cont’d)
To replace the batteries, follow these steps:
1. Turn instrument off.
2. Remove battery cover by sliding down.
3. Install new battery to the wire leads observing correct polarity.

Cleaning the OPM and SLS Interfaces
Make sure that the instrument is powered off. Do not look into the
output of any SLS port. Unscrew the OPM adapter and use a clean lint
fee wipe to clean the exposed OPM detector window. Always use a new
2.5mm cleaning swab to clean the SLS bulkhead.

Applications
The following applications for the berTOOLS instruments are
described in this manual:
• Connector/cable insertion loss measurements
• Link loss measurements
One Test Jumper Method: Connector Loss
1. Connect an appropriate light source to the optical power meter
using a suitable reference cable with a length of about 2 to 3
meters (6 to 10 feet).
2. Ensure that the light source is in continuous wave (CW) output
mode. Set the optical power meter to the appropriate wavelength
(using the [ ] key) and to dBm units (using the [dB/dBm] key).
3. To store the reference level, press the [dB/dBm] key on the optical
power meter until the display reads 0.00 dB. See below.

Two Test Jumper Method: Link Loss (cont’d)
1. If a complete test set (light source and optical power meter) is
available at each end, it is advisable to test the output power of
the sources and the condition of the test jumpers before
commencing measurement of the link.
Connect each source and optical power meter with a test jumper,
as shown above. The sources should be set to continuous wave
(CW) output mode. The power meters should be set to the correct
wavelength and to dBm measurement units. Note the P1 and P2
dBm readings. For example, a SLS520 1310 NM laser source
should read approximately -1dBm on the optical power meter.

optical power meter (P3) and the nominal source output value,
corresponding to the light source in use.
Note: Make sure the optical power meter supports the wavelength
of the light source in use.
4. It is advisable to measure the loss in both directions. Reverse
the source and optical power meter connections, as shown above.
