Attention 
All statements regarding safety of operation and technical data in
this instruction manual will only apply when the unit is operated
correctly.
Use only the power cord specified for the unit.
Do not operate the power meter if its panels are removed or any of
the interior circuitry is exposed
Do not operate the power meter in wet or damp conditions, or in an
explosive atmosphere.
Operate the power meter only within the specified voltage range
Do not apply voltage outside the specified range of the input connec-
tions

Attention 
This equipment has been tested and found to comply with the limits
for a Class A digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commer-
cial environment. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance
with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is
likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.
Standard shielding and filtering measures have to be undertaken to
avoid interferences with other electronic equipment!
NOTE
Please check prior to operation, if the line voltage range, indicated on the
power supply agrees with your local supply

2 Description
The Thorlabs PM30 Power Meter system is an easy to use, flexible optical power
measurement system with optical sensor. Its mechanical analog needle display
features best readability and real time response for fast laser tuning. The additional
digital display allows accurate power readings and a convenient system setup.
The Thorlabs’ optical power meter sensors feature NIST traceable wavelength
calibration over the specified wavelength range. Please refer to www.thorlabs.com
for new sensors that will enhance the PM30 system.
The console is powered by a 6V, 150mAh nickel-metal-hybrid (NiMH) battery for long
life operation and fast recharging times. The included external power supply is
provided to recharge the battery pack as well as to operate the unit.
2.1 Parts List – Accessories
The power meter system consists of the following items:
•PM30 power meter console
•Operation manual
•PMPS12 Power supply (12V, 0.85A), 90 .. 264V line voltage,
line adaptors for US, EU, UK.

Analog Meter Shows the measured power level on the scale that
corresponds to the selected power range. An up showing
arrow in the digital display indicates that the 10-division
scale is used, a down-showing arrow indicates the 3-
division scale.
LC Display The 12 digit LCD allows precise power measurements
along with additional system information and input capabili-
ties. The LCD can be backlit in two brightness settings in
