1. Power On/Off and Auto-off Function
Press the button to turn on the instrument. Press it again for 2 seconds or
more to turn it off.
This power meter has a power-saving function. If 10 minutes without any
operation, the instrument will automatically shut down. If you need to disable this
function, only need to press the button for 2 seconds when you turn on the
instrument till it displays "PERM".
2. Backlight Function
When the instrument is powered on, short press the button , you can control
the backlight function on or off. The backlight function supports you to use the
power meter at night or darker occasions.
3. Wavelengths
According to the project, we need to measure optical signals of different
wavelengths.
Then we need to select a corresponding wavelength to measure the optical
power. If the wavelength needs to be measured does not match with the
wavelength we select on the optical power meter, it will lead to the measuring
values meaningless.
Press the button , the instrument will change wavelength, and display.
FOPM-201/FOPM-202 optical power meter calibration measured wavelengths are:
850nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm.
4. Unit
button can be used to change the display unit of the measurement data to
meet the different requirement. When press this button for 2 seconds, the display
will successively show the dBm value or mW/uW value.
The numeric relationship between mW value and dBm value is: 10lg (mW) =
(dBm).

EN
5. Reference
button is used to set or check the reference value. Short press this button, the
display will show "REF" and the dBm value saved as reference value. When long
press for 2 seconds or more, the instrument will save the current dBm value as a
new reference value. Meanwhile the "REF" sign will flash 3 times on the display.
After that the display will show the dB value. Each wavelength can set its
reference value.
6. Visual Fault Locator Function (Optional)
When power meter with visual fault locator, you can short press the button to
control VFL status (on, glint, or off).

1. Power On/Off and Auto-off Function
Press the button to turn on the instrument. It will automatically go to test
menu. In test menu, short press the button (less than 2 seconds) to activate
or deactivate the auto-off function. The auto-off function means the instrument
will shut down automatically if the instrument has not been operated for a certain
period of time. The time period can be set and the default is 10 minutes.
2. Test Mode Switch
In the test menu, press the button to switch between normal test mode and
P/F test mode.

directly. In this mode, the LED indicators will not light. The results are displayed in
2 units: dB and dBm, using button to switch. See Fig. 1.
Unit dBm is to display the actual power.
Unit dB is to display a power value relative to a reference value. In this mode,
reference value needs to be preset correctly.
(2) P/F Test Mode
P/F test mode means the measured light power comparing to a preset threshold
value to determine if the measured light power meets user’s requirement or not.
LCD will display the optical power and current state. The LED indicators below the
LCD display will also change color to match the current state of measured light.
This test mode is very useful in some special cases required. See Fig. 2.

3. Threshold Setup
The user can set up the value. The steps are as following:
In the menu mode, select the second "Threshold Setup" enters to threshold setup
menu. See Fig. 3.
In this menu, left side displays wavelength and right side displays threshold value.
Top line indicates system information (date and time) and bottom line indicates
the information of threshold including threshold symbol, threshold number and
name.
In this menu, short press Threshold button (less than 2 seconds) to switch the
wavelength among 1310nm, 1490nm and 1550nm. Press button ▲( ) to
view the previous record, button▼( ) to view the next record, button
to validate the current threshold value. After the above operation, all P/F mode
test results will base on this threshold value.

4. Time Setup
In the menu mode, select the forth "Time Setup" enters to time setup menu. See
Fig. 4.

In the time setup menu, the button becomes arrow button - using it to
move cursor. When the cursor moves to a number, the user can use button ▲to
increase the value and button ▼to decrease the value. When the cursor moves to
"Yes" and press the button for more than 2 seconds, the " Yes" will flash,
means the instrument accepts the time change. During the time setup, the user
can press the button (less than 2 seconds) to exit time menu and back to the
test menu, then the system time setup remains unchanged.
5. Unit Switch
When the instrument is in normal test mode, press the button can switch
the unit between dBm and dB. Here, the unit dBm is the actual power and unit dB
is a power value relative to reference value. Refer to the next section about
"Reference Value Setup". When the instrument is in the P/F test mode, pressing
the button will automatically exit P/F test mode and switch to normal test
mode. Its unit will be in dB.
6. Reference Value Setup
In the test menu, press the button for more than 2 seconds, then the LCD
will display "REF" in red (see Fig. 5). This means the instrument chooses the
current light power as the reference value. The test results afterward are the
values after comparing to this reference value. Now, the unit will be in dB and LED
below the LCD display will not light.

2. OPM Mode
This mode has two main functions, multi-channel power meter (as shown in Fig.

Multichannel optical power meter: it is equivalent to a 12-channel optical power
meter, which supports the selection and release of a single channel or all
channels. The wavelength of individual channels can be edited when selected,
and the global operation of all channels can be carried out when all channels are
selected.
