Edmund Optics or your local distributor if extra power supplies are needed for a
particular setup.
USB INTERFACE CONNECTOR
This interface allows remote control and data transfers between the USB POWER METER and a
computer that has a USB communication port. With the RS-232 USB POWER METER, this
connector is use as a RS-232 com port.

USB POWER METER User Manual Revision 17.0 4
ANALOG OUTPUT
For monitoring laser average power or energy by using external equipment such as a chart
recorder, a computer with an analog interface, a voltmeter, etc.
The output signal represents a DC analog voltage proportional to the amplified and anticipated
power detector response in the case of a power measurement. In the case of an energy
measurement (energy mode), the output signal is a DC voltage representing the pulse energy
value.
The user must enter the maximum value in the Settings  SET Max Analog Out Range. This
value is the value at which the analog output equals 2.05 V. That provides the best signal-to-
noise ratio. The measured power or energy is then related to the output voltage and to the
selected range according to the following equations:
V
out
= Measurement * 2.05 / Max Analog Out Range
For example, with a 10 W max analog range:
2.05 V corresponds to 10 W
1.025 V corresponds to 5 W
Another useful example: To set the analog output so that 1V corresponds to a measurement of
56W, the Max Analog Out Range must be set to 20.5 according to the following equation:
Max Analog Out Range = 56 * 2.05
Specifications on the analog output:
Maximum output voltage: 2.05 V
Output impedance: 274 
Connector type: Female 1/8” jack
PROBE INPUT JACK
The USB POWER METER uses a DB-15 female connector to mate with the detector heads
(probes).
The USB POWER METER works with all Edmund Optics power detectors. It automatically
recognizes every power detector head, which ensures accurate auto-calibration. More
importantly, it can take advantage of our Personal wavelength correction™. It reads the memory
in the Smart Interface connector (version 5 and higher) to provide a wavelength correction that is
based on spectral data measured from that specific detector.
The USB POWER METER may not recognize some of the earlier heads.
WARNING
This DB-15 connector, though similar to that of the former TPM-310 and TPM-330
monitors, is incompatible with the power detector heads of PS-310 Series Version 1 and
PS-330 Series Version 1. These heads used a different technology and do not have the
same pin-out configuration.
The Edmund Optics C-300 adaptor can be used in order to connect the power detector heads of
PS-310 Series and PS-330 Series Version 1 and 2. Please contact your local Edmund Optics
distributor or the nearest Edmund Optics office for further information.
Any attempt to modify connectors of the early version heads to mate with the USB POWER
METER can result in damage to the monitor.

2. OPERATING INSTRUCTIONS
First, you have to install the PC-PREMIER software on your computer, along with the USB drivers. Please
find the latest version on our website. The software will automatically connect to the first COM port
available. As soon as you are connected, you are ready to adjust the settings (please refer to the PC-
PREMIER manual).
2.1. INSTALLING THE USB DRIVERS
Plug the USB POWER METER into a USB port on the PC. If the PC supports USB 1.1, Windows detects
the new device and prompts you for the software drivers. A window will open that says “Found New
Hardware – USB Device” and after a few moments, the “Found New Hardware Wizard” will appear.
The USB drivers are available on our website.
Please note that old monitors without the (R2) at the end of the product name need different USB drivers
which are available on our website also. They do not support Windows VISTA, unless noted on the
website.
At the end of this process, a new serial COM port will be added to the list of communication ports. It may
be used as any other serial port. You will need to know the COM port number to set up the serial
connection to the USB POWER METER.
Verify COM Port
To verify the USB installation and find the COM port number, open the device manager and scroll down
to Ports (COM & LPT) and double click that line. One of the options should be:
USB-to-Serial Port (COM#)
Note the COM port number, you will need it for the next step.

USB POWER METER User Manual Revision 17.0 6
2.2. QUICK MEASUREMENT PROCEDURE
This section shows you the fastest way of making a laser power measurement with the USB POWER
METER.
The monitor automatically recognizes all the Edmund power heads of version 4 or higher. All custom
technical data required for optimum operation of the detector will be automatically downloaded from the
EEPROM in the DB-15 connector. This data includes sensitivity, model, serial number, version,
wavelength correction factors, and time response. In case of a conflict, use the sensitivity on the most
recent calibration certificate. The USB POWER METER must be disconnected from the PC before
connecting a new head in order to prevent any lost of data from the detector’s head EEPROM.
1 Install the power detector head on its optical stand.
2 First, slide the connector latch to the right to unlock the connector.
3 Connect a version 5 (or higher) power or energy detector head to the USB POWER METER
using the PROBE INPUT JACK while the USB POWER METER is disconnected from the PC.
4 Slide the latch to the left to lock the connector into place.
5 Connect the USB cable to your computer for the USB model or, for model RS-232, plug the
RS-232 cable to your computer and then the power supply.
6 Open PC-PREMIER and click on the Connect button in the Ribbon menu.
7 If you have a photodiode, to obtain measurements in dBm, select Measure Mode / dBm.
Adjust the Zero (Steps 8 to 10)
8 Remove the head’s protective cover.
Put the detector head into the laser beam path. The entire laser beam must be within the
sensor aperture. Do not exceed maximum specified densities or powers. For the most
accurate measurement, spread the beam across 60% to 80% of the sensor area.
Note: Power heads can be used with both CW and pulsed lasers.
9 Block off the laser radiation to the detector.
10 The power read by the USB POWER METER when no laser beam is incident on the detector
may not be exactly zero. This is because the detector is not thermally stabilized OR there was
a heat source in the detector’s field of view when you turned on the USB POWER METER.
11 To reset the zero, wait until the reading has stabilized and select Zero Offset button in the
Ribbon menu. Note that the Zero Offset process can take about 20s for a photodiode. It is
much quicker for other detectors. You are now ready to make an accurate measurement.
Notes:
 Refer to specific power detector documentation for complete installation and operating
instructions.
 The power detectors are thermal sensors sensitive to temperature variations.
 For high-precision measurements, it is recommended to:
 Allow the power detector temperature to stabilize before zeroing the USB POWER
METER.
 Do not touch the detector head when handling the power detector. Touch only the stand.
 Avoid forced airflow or drafts around the detector.
12 Apply the laser beam to the detector head.
13 The laser beam average power will be displayed in three ways for your convenience:
 Digitally for real time measure.
 On a histogram to allow the laser beam’s long-term stability to be evaluated.
 On a digital needle for laser tuning.
