Power value：
it displays the current output power under
absolute test mode
it displays the difference between the current
output power and reference power under
relative test mode
Unit：mW、uW、nW、dBm、dB
Relative test：press dB to start relative test
Auto-off：activate the 10-minute auto off function
Battery level：real-time indicate the battery level.
When blank, it indicates the power is too low
6.2 Function
1) ON/OFF ：click ON/OFF to turn it on. press
for 3 seconds to turn it off. Under power-on
mode, press this key shortly to activate or
deactivate the 10-minute auto off function
2) dBm/W ：press dBm/W to enter absolute test
mode. Press it again to switch the test unit.
3) λ ：switch the wavelength from 6 calibrated
wavelength
4) dB ：press dB key once to enter relative test
and it has 3 working mode:
A) directly enter the relative test: under
absolute test, press this key to enter the relative
test. now the Ref value shows the previous
power values.

B) Reference value storage：when enter
the relative test, press dB for 2 seconds to save
the current absolute power value as REF value
and show the relative power value in dB unit
c) Enter the relative test and save current
reference value: under the absolute test mode,
press dB for 2 seconds to enter the absolute test
mode and save the current value as reference
value which is showed in Ref position. Now
the value in dB unit on the screen is the
difference between the real test value and
reference value.
5) Backlight is on when turning on the unit. it
would auto turn off 1 minute later. You could
press any key to turn it on for 1 minute again.
7 Operation
7.1 Turn on/off
Press ON/OFF shortly to turn on the unit.
press it for a few seconds to turn it off and
click it to activate or deactivate the auto-off
function.
7.2 Absolute power measurement
Connect the power meter with optical signal
Turn on the power meter
Choose the correct wavelength via λ key.
If the tested wavelength is not exactly same to
the one in the power meter, then choose a

close one from the power meter.
Press dBm/W to choose the display unit. the
default wavelength is 1310nm and working
mode is dBm.
Then the power meter will show the test
power value.
7.3 Relative power test
Set wavelength
Press dB for 2 seconds to enter the relative
test mode. now LCD screen display 00.00dB
Connect it to the test signal. the current value
is difference between the tested value and
reference value.
Reference value is in the Ref position
Press dBm/W to review the current absolute
power value. Press dB to review the current
reference value

Take out the battery and pull up the switch 1
to “ON” position.
Put the battery back to the battery
compartment and turn on the unit to choose
the wavelength for calibration.
Now connect it with pigtail and press REF
or dBm/W to increase or decrease the data by
0.05dB.
When the value is same to the one in the
standard power meter(or lower 0.03dB), press
on/OFF to save the changed result.
Repeat above operation for other wavelength
After recalibrate each wavelength, please pull
down the switch 1 (come back to the position,
the opposition of the “ON” )and turn off the
meter
End the user self calibration operation
7.5 Auto off function
The auto off is on when turning on the unit.
Press ON/OFF to activate or deactivate it.
7.6 Replace battery
If the battery level is very low, please turn off
the unit immediately and replace the batteries
Take out the battery if not in use for a period
of time
NOTE: do not charge the non-rechargeable
battery, dangerous!
