PRODUCT DESCRIPTION
The Jonard Tools Mini Optical Power Meter is perfect for measuring both the
absolute optical power and relative power loss in fiber optic cables. It also
features a built-in visual fault locator, network cable tester and remote.
The Mini Optical Power Meter measures a wide variety of wavelengths from
800-1650 nm, with a mere 0.01 dB resolution and has 10 preset calibrated
wavelengths with high precision to determine absolute or relative power.
The LED screen is backlit for viewing in low light locations and a 10 minute
auto-off helps preserve battery life.
Built-in 2 mW visual fauit locator (VFL) identifies faults in fiber cable in a
pinch.
Tests RJ45 connected network cables using built-in remote.
The Mini Optical Power Meter also comes with FC and LC adapters so that fiber
connectors can be directly connected to the tool. The FC/SC adapters are for
APC/PC/UPC connectors and the LC adapter is for PC/UPC connectors only.
OPERATING INSTRUCTIONS
POWER ON/OFF AND AUTOMATIC SHUTDOWN
Adter pressing briefly, the meter will tun on and start the automatic shutdown
function. The default automatic shutdown time is 10 minutes. If you want to
cancel the function, press and hold the power button for two seconds, and the
icon disappears, the automatic shutdown will be cancelled.
SET REFERENCE OPTICAL POWER
After powering on, enter the interface of OPM, press REF to set the current
power as the reference power, switch the relative optical power test
(insertion loss test) and absolute power test. In the relative power test
mode, the insertion loss (dB) and the reference value is displayed
simultaneously. Short press the dB key to switch linear power and absolute
power display.
The units of linear power, absolute power and relative power are W, dBm and dB
respectively.
Pabs.p = 10lglin.p/ImW; Prel.p = Pabs.p – Pref.p
SWITCH THE WAVELENGTH
In the interface of OPM, short press the A key to switch the measurement
wavelength. Ten different wavelengths can be selected: 1310nm, 1550nm, 1577nm,
1490nm, 1625nm, 1650nm, 850nm, 1270nm, 1300nm and 980nm.
In order to ensure the accuracy of the test, the selected wavelength must be
consistent with the measured optical signal.
RJ45 CABLE SEQUENCE AND ANALOG CABLE TRACKING
In the test interface of OPM, long press the dB key to display the word “RJ45″
on the screen. At this time, enter the RJ45 cable sequence test, connect one
end of the network cable to the RJ45 port in the bottom, and connect the other
end to the remote tester.
Short press the dB key to exit. Long press the dB key again, “ ” displays on
the upper left corner of the screen, enter the cable tracking mode, and short
press the dB key to exit.
VFL AND LED FLASHLIGHT
After powering on, long press the / VFL key to turn on the VFL, short press to
flash and turn off. Press the power button to control the flashlight to turn
on and off.
CALIBRATION INSTRUCTIONS
At the same time, press the LED+ REF keys to clear the user’s calibration
value, and the screen will full display “-” to restore default value; press
the LED+VFL to enter the calibration mode, and “Cal” will be displayed in the
upper left corner of the screen.
The following operations are only valid in the calibration mode.
