5 System operation
5.1 Connection and Setup
Connect the detector to the DB15 connector on the flank panel of the optical power meter. The
optional external power supply of the power meter is including rechargeable battery and power
adapter.
Attention: please turn off the power supply when you Connect/Disconnect the detector.
5.2 Starting up
（1）It shows ----after starting up. It will last 1 second and it means the optical power meter is in
self-inspection. When the detector is successfully to connect with the optical power meter, there will
be SN showing on the left of the screen. And then it will enter the measuring mode. If the screen
shows “nC”, that means the detector is fair connection with the optical power meter.
（2）After the optical power meter enter into measurement mode by default, the wavelength will be
shown on the upper left corner. Default wavelength value is determined by the type of detector. For
example, the default wavelength value of Silicon photodetector and Silicon-UV enhanced
photodetector is 650nm, the InGaAs 1350nm and the thermopile 10 um. The middle shows the
measured power value, and the default unit is W; Automatic shutdown and intelligent backlight turn
off by default.
5.3 Setting the Wavelength
For accurate measurement, It is necessary to set the Calibration wavelength to the Incident
wavelength. The Calibration wavelength is indicated in “nm” on the screen. Once starting up, the latest
stored date is used as the Calibration wavelength. (If it is on the first time, the wavelength value is the
default set). If the light source is broadband, use either a value near the center wavelength of the light
or the wavelength with greatest intensity. Pressing the λ▼/λ▲keys will switch the saved
wavelengths .If the customer wants to add a new wavelength,long pressing “Mw/dBm /MODE”key to
enter the setting wavelength model,short pressing λ▼/λ▲to set wavelength and short
pressing”SAVE/DELETE”key to save the wavelength. The number of saved wavelengths will be
displayed in the center of the screen. Long pressing “Mw/dBm /MODE”key again to return the
absolute power measurement mode,and short pressingλ▼/λ▲can switch the saved wavelengths
Chapter 5
Attention
The response of the detector depends on the wavelength of the incident light. Please refer to the manual and
test data to determine suitable wavelength.

5.4 Setting the Attenuator Mode
If the light intensity more than the detector’s Saturation value, you have to order the attenuator to get
the right data.
In the attenuator mode:
a) ATT signal indication
b) The response of detector - attenuator will be used in the process of verification
Please long press the “ATT” to close the attenuator models when the attenuator is removed.
5. 5 Setting the power limit
If you need to define power measurement range, It can be set to measure the power of the upper and
lower limits. In absolute measurement mode, you can enter setting lower limit mode by long pressing
twice. Long pressing twice again, you can enter setting upper limit mode. Waiting
10seconds or long pressing again, you can enter absolute measurement mode. If the measured
power exceeds the upper and lower limits, it will buzzer. The function is very convenient and effective
to the stability testing of the light source. Without attenuator, the lower power limit is 0.001nW and
upper power limit is 10mW by default. When the attenuator is open(10X、100X or 1000X), the upper
power limit will expand to 10×10mW、10×100mW or 10×1000mW as well.
5.6 Measurement
5.6.1 Absolute power measurement （mW/dBm）
The absolute power measuring has two representation, dBm or W, and short press can change
the measurement units to dBM or W.
dBm reading=10*lg[Net Applied Power/1mW]
Measurment steps:
a)Short press , choose watt or dbm measuring mode, set the wavelength of the light source.
b)Shield the light source which you need to measure
c)Short press and remove the initial background signal. Display should read approximately zero,
but will fluctuate depending upon the variations in the amount of light reaching the detector and the
detector dark current fluctuations.
d) Select the appropriate attenuator according to the photometric intensity, (Suggestion: there is no
need to add the attenuation slices when the light source is lower than 1mw.
e)shine the detector with the signal light source and readout.
Attention
Try to reduce the influence of stray light while measuring. For example, turn off the light in the house
and remove other equipment. Avoid the light focusing on the surface of the detector, or it will damage
the detector. For the saturation and optical damage threshold of the detector, please refer to relative
detector manual.
Attention
Please note that different attenuator will have different light transmission characteristics, the SN of the
attenuator should be matched with the detector while using.

5.6.2 Relative measurment（dB）
The dB measurement mode displays the absolute value of 10 times the logarithm (base 10) of the
input power, referenced to a power level which is selected by pressing the REF key. The following
equation illustrates this relationship:
dB reading=10*lg[Net Applied Power/Net Referenced Power]
=10*lg{[(P-PZ)]/[(PSTOREF-PZ)]}
P detector input power
PSTOREF Absolute power value of reference light
PZBackground light power value in zero clearing
Measurment steps:
a)Automatically adjust the signal range and choose the wavelength
b)Shield the light source which you need to measure
c)Short press and Remove the initial background signal. The data should be close to zero. But in
fact the data will be fluctuated because of the flux and the dark current of the detector.
d)Let the reference light shine in the detector .
e)Long press REF until the screen shows REL, keep down the reference signal power value PSTOREF
and enter the relative measuring mode.
f)Use the light which need to be measured shining in the detector.
g)Read out.
5.7 Saving and delete
You can long pressing “save” to store the wavelength, the upper and low limite of the power value and
the status of the attenuator. The last stored measurement condition still can be used after restarting.
There is no need for you to resetting. When you long press the “save”, the new data would be stored,
and it will replace the last stored data. If you do not store the measurment data, it will keep the
factory settings mode after restarting. Long pressing (until a “beep” is heard) can delete all stored
data and go back to the factory settings mode.
5.8 Introductions for reseting
When replacing the different types of detector, if the header fails to identify, you can long press the
button (until a “beep”is heard) to restore the factory settings.
Attention
The reference light source and the light source which you want to measure should measure in the same
condition. The background PZshould try to be consistent, to make sure the reference power and the
measured power bigger than PZ, otherwise the dB measurement is no practical meaning, and an Erro
message is indicated on the screen.

5.9 Shutdown
Long pressing the , when the auto- shutdown function is open, if there is not any operation in
10mins, it will Auto Power -Off . After startup, press the Power Button last more than 1 second again,
the power meter will be shutdown.
Attention
Please read the manual and know well about the specification of the detector, the wavelength and the
power value of the light source before testing. If they are more than detector responsivity and damage
threshold, please choose the right attenuator and do not focus the light source directly on the detector. If
there is something wrong with the power supply system, the host display may be abnormal, please shut
down as soon as possible.And do not start up before the power supply system works well.
