PM30 / page 8
2.3 Operating Instruction
2.3.1 Battery Charging
The PM30 has a built in NiMH rechargeable battery for an operation up to 50hrs
(without backlight). When the batteries need recharging an empty battery sign
appears on the right side of the digital display.
The batteries are not fully charged when shipping. A battery that is new or has not
been used for a longer period does not develop its full capacity until after
approximately 2.5 hours of charging.
Plug the in the delivery included 12DC power supply to the input connector in the top
panel and the power supply into a suitable AC outlet. Attach the right adapter
depending on local power requirements to the power supply, adapters for US, Europe
and UK are provided with the instrument. If the adapter is lost, contact Thorlabs for
replacement.
When the charger is plugged a filled battery sign in the LC display indicates that the
charger works in “full-charge” mode, the charging circuit goes automatically in
“trickle-charge” mode when the batteries are fully charged. In this case the indicator
in the LCD changes to a wall-plug sign.
Do not exceed the line voltage that is stated on the power supply. The power supply
gets warm after longer time of use; this is normal and not dangerous.
The unit can be operated normally while the 12VDC adapter is plugged in.
2.3.2 Connecting the Optical Sensor
Plug the DB-9 connector of the optical head into the jack located on the top of the
console and secure the two screws. Thorlabs S1xxX Sensors can be plugged or
changed while the power meter is switched on. The display unit will automatically
recognize the sensor and work with the appropriate calibration data, that are
downloaded from the non-volatile memory in the sensor connector.
2.3.3 Switching on and off the PM30
If the unit is not already switched on, turn the main switch from the OFF position, the
PM30 will power up and show the connected sensor data and for approximately 3
seconds the set wavelength. The unit will stay on until the selected auto-shutdown
time that can be set in the system menu is reached. After this time the PM30 will
Page 13
2.3 Operating Instruction
PM30 / page 9
automatically switch of for battery saving. To power up the unit again the rotary
switch has to be put to the OFF position and then back to one operating position, the
unit will continue measuring with the set conditions prior to shut-off.
To manually shut down the PM30 turn the main switch to the OFF position. All
system and measurement settings will be present when turning the unit on again. To
keep set values the unit must be on for a minimum of 10 seconds after changing the
set value.
2.3.4 Setting the Operating Wavelength
Turn the left rotary switch into the λ-position, the digital display will show a
wavelength in nm. Click on the control button to enter the wavelength set menu, by
each click a digit of the set wavelength will get underlined. By turning the control
button each digit can be scrolled up and down in the sensor wavelength range. The
set values are immediately used for the power calculation. To leave the menu turn
the main switch back to the P-position. After 10s the wavelength set value will be
stored in the PM30 console and is present after shutting off and on the unit (when
using the same type of sensor!).
The minimum and maximum settable wavelength is sensor dependent and
downloaded to the instrument when connecting the sensor.
2.3.5 Measuring the Optical Power
Turn the unit into the P-position, place the sensor in the path of the laser beam,
conduct one-time auto-ranging by clicking the control button, or select a power range
manually by turning the control button, and read the optical power on the range
corresponding scale or in the digital display.
The PM30 usually works in manual-range mode. The power ranges can be set in x3,
x10 steps, after setting the current power range is indicated for approx. 1s in the LC
display. After this time the LCD switches back to the power reading, that includes the
power units and the corresponding scale of the analog meter.
The minimum and maximum settable power range is sensor dependent and
downloaded to the instrument when connecting the sensor.
Attention
Refer to the sensor data sheet and pay attention to the optical
damage threshold!
Exceeding these values will permanently destroy the sensor!

PM30 / page 10
2.3.6 Relative Measurement
This feature can be used either for backlight subtraction or performing a relative
measurement.
Turn the unit into the ∆-position. Click the control button to subtract the current
reading. The digital display shows the subtracted power reading, the analog needle
goes to zero.
Turn the main switch back in the P position. The digital display now shows the
difference to the subtracted reading followed by a ∆ sign. Power ranges can be set
only in the Up position.
2.3.7 System Menu
To enter the system menu turn the main switch to the SYSTEM position. The system
menu allows the following settings / contains the following information:
The menu can be navigated by turning the control button. Submenus are entered by
clicking the control button.
Shutdown: Sets the time after that the unit automatically switches off.

System SN: Shows the serial number of the device.
Version: Displays the firmware version
Sensor Name: Displays the type of the connected sensor
Sensor SN: Shows the serial number of the connected sensor
2.3.8 Photodiode adapter
Instead of a calibrated power meter sensor the optional available photodiode adapter
PM30PDA allows to use the PM30 as a current and power display for any floating or
anode grounded photodiodes with a photo current up to 4mA.
Plug the adapter on the PM30 sensor connector input and tighten the fixing screws.
The photodiode cathode has to be connected to the center, the anode to the shield of
the adapter’s SMA input connector.
The operation is similar to the standard operation. Instead of the wavelength a
responsivity value can be set to perform a single point power calibration. The setting
Page 15
0
PM30 / page 11
range is 1mA/W to 99999 mA/W. The default responsivity value is 1000 mA/W, so
the power reading will correspond directly to a current reading in A.
Refer to www.thorlabs.com for directly connectable anode grounded photodiodes
from the type SM05PD and SM1PD and for suitable SMA connection cables.
2.4 Remote Control
The PM30 has a built in serial interface to operate the unit remotely or upload new
firmware.
It is not possible to change device settings locally while the device is in remote
operating mode. If the Interface is connected and active, the device will not shutdown
automatically regardless of the Shutdown setting.
The device is considered to be a Data Terminal Equipment (DTE). To connect it with
a control PC use a 9 pole null-modem cable which is connected like shown in the
following figure.
Set up your control PC to meet the following communication setup:
Line setup: 9600-8N1-RFR/CTS

4.6 Thorlabs “End of Life” policy (WEEE)
As required by the WEEE (Waste Electrical and Electronic Equipment Directive) of
the European Community and the corresponding national laws, Thorlabs offers all
end users in the EC the possibility to return “end of life” units without incurring
disposal charges.
This offer is valid for Thorlabs electrical and electronic equipment
• sold after August 13
th
2005
• marked correspondingly with the crossed out “wheelie bin” logo (see fig. 1)
• sold to a company or institute within the EC
• currently owned by a company or institute within the EC
• still complete, not disassembled and not contaminated
As the WEEE directive applies to self contained operational electrical and electronic
products, this “end of life” take back service does not refer to other Thorlabs
products, such as
• pure OEM products, that means assemblies to be built into a unit by the user
(e. g. OEM laser driver cards)
• components
• mechanics and optics
• left over parts of units disassembled by the user (PCB’s, housings etc.).
If you wish to return a Thorlabs unit for waste recovery, please contact Thorlabs or
your nearest dealer for further information.
4.6.1 Waste treatment on your own responsibility
If you do not return an “end of life” unit to Thorlabs, you must hand it to a company
specialized in waste recovery. Do not dispose of the unit in a litter bin or at a public
waste disposal site.

4.6.2 Ecological background
It is well known that WEEE pollutes the environment by releasing toxic products
during decomposition. The aim of the European RoHS directive is to reduce the
content of toxic substances in electronic products in the future.
The intent of the WEEE directive is to enforce the recycling of WEEE. A controlled
recycling of end of live products will thereby avoid negative impacts on the
environment.
