The leftmost window lists out the detected devices, the middle window shows the selected devices,
and the rightmost window is the information of the selected device.
【Add】button
Select a device in the Available Devices window on the far left and click the Add button, the power
meter would be automatically added to the Selected Devices window, and the measurement channel
is created.
【Remove】button
As a device in the Selected Devices window is selected, then click the Remove button, the selected
device moves back to the Available Devices window.
(2) Bluetooth connection
For Bluetooth communication, please check【Search wireless devices】as shown in Figure 4,
Bluetooth devices would be found out automatically.
Before adding a Bluetooth device, make sure that your computer’s Bluetooth functions well. The
procedure for Bluetooth connection may not be the same in different operation systems or different
Bluetooth manufacturers. Here is an example for WIN7 operation system:
On the taskbar in the lower right corner of the computer screen, right-click the Bluetooth icon and
choose Add Device. As the wireless power meter is detected, a device with BIM-7XXX-XXXX would be
shown as Figure 5:

Sampling frequency, Unit Hz
ATT
OUT: not using attenuator, IN: using attenuator
Range
Optical power range, use mouse to select the range or type-in
manually
Average
Averaging the data and show in the analysis page
NONE: Averaging all data
11sec, 3sec, 10sec, 30sec: Averaging the data collected in 1, 3, 10,
30sec respectively
Offset
Set power offset
Tick for activating the offset ,
Click this to set the current value as the offset
Scale factor
Factor for multiplying the measured values to show as the results
dBm
Use dBm as the unit or not
dB offset
Use dBm as the offset unit. The power offset is invalid once this dB
offset is applied
Trigger mode
Default setting is normal. External trigger mode can be selected,
please see below for the details
Zero
Set zero. Click this to take a measurement under no light
environment , the reading would be set as zero
Logging
Control data logging running or stop
Stop Condition
Condition to stop data logging:
Manual: Stop manually
TimeOut: set timer to stop the data logging
Duration
Set measurement Duration
Trigger Mode
External trigger can adapt TTL with 5V maximum. While the wireless power meter is operating in this mode,
it is stand-by until receiving the first rising edge of the external trigger signal, then power meter starts to
collect data once getting another rising edges of external trigger signal.
Zero
Before measurement, “set zero”function should be used for removing the background noise within the
detector and instrument. This can minimize the influence of background noise to the result.
Shield the detector window such that it is completely in the darkness
Click button to set zero
Take measurement

Real-time graph displays the spectrum when the spectrometer is running, X-axis for the time, Y-axis
for the power.
Setting Spectrum Pane:
Adjust Y-axis range：
Put cursor on the Y-axis until appearing an icon, scroll the mouse wheel, or press the left button
and drag the cursor up or down to adjust the Y-axis range. Alternatively, the range can be selected
in the setup pane.
Adjust X-axis range:
Put cursor on the X-axis until appearing an icon, scroll the mouse wheel, or press the left button
and drag the cursor up or down to adjust the X-axis range. Alternatively, the range can be also
changed by putting the value in Time Frame.
Move pane:
Put the cursor to the pane, press right button, move anywhere wanted.
Zoom-in/Zoom-out
Put the cursor to the spectrum, scroll the mouse wheel.

(11) Analog Output
This power meter has analog output which provides real-time value for close-loop monitoring.
The output range can be controlled by setting the maximum and minimum values.
The minimum and maximum powers can be set to have the interested power range
The analog output voltage and power have linear relationship. Please check the product manual for the
voltage output range of the power meter.
For example, the minimum and maximum power are set 4.5W and 45W respectively, the minimum
and maximum value of analog signal output would be 0.45V and 4.5V. If the power is 30W, the
analog voltage output would be 3V.
Note: For having accurate analog signal output, the maximum output voltage should not be set
greater than 4.8V.
