After short press the power button,
the meter will turn on and automatically
start the automatic shutdown function.
The default automatic shutdown time is
10 minutes. To cancel this function, press
and hold the power button when the power
is turned on. When the power button dis-
appears, the automatic shutdown will be
canceled.
Insert the fiber under test into the
VFL interface, press the VFL key to enter
the VFL test interface.

TPV-53 is a combination of optical power meter and VFL. Among
them, the optical power module can be used to measure the optical
power in mw, dB, dBm within the wavelength range of 850~1700nm,
with high display resolution. There are seven wavelengths calibration
points at 850nm, 980nm, 1300nm, 1310nm, 1490nm, 1550nm and
1625nm. It can display both linear and non-linear optical power at the
same time, which can be used for direct measurement of optical power
and relative measurement of optical link loss. The VFL module provides
650nm visible laser output, the test distance can reach 10km, and the
output power can reach 1mW/10mW/20mW. It is suitable for
single-mode or multi-mode fiber measurement and can identify
optical jumpers, jumper boards, distribution frames, and connectors
fault at the place.The instrument has a continuous backlight display
function, a large LCD display, making the measurement work more
conveniently and quickly,it is the construction of cable television
systems, optical fiber communications and other fields Indispensable
equipment for maintenance.

Insert the fiber which is under test into the
OPM interface.After booting, enter the
optical power meter interface, short press
the "REF" key to set the current power value
as the reference power, which can achieve
relative optical power test (insertion loss test)
or absolute power test, enter the relative
power test mode at the bottom of the screen
Display insertion loss (dB).The screen displays
the reference value; short press the "dB" key
to switch between linear power and absolute
power display.The units of linear power,
absolute power, and relative power are nW,
dBm, and dB respectively.

On the optical power meter interface, short
press the "λ" key to switch the measurement
wavelength, select 7 different test
wavelengths, 850nm/980nm/1300nm/
1310nm/1490nm/1550nm, 850nm, 1625nm
to ensure the accuracy of the test, select
the wavelength should be consistentwith the
wavelength of the measured optical signal.
