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.

Depending on the order code the power meter system comes with one of the sensors

given below:

PM30-120: S120B – Silicon Sensor Power Head; 50nW – 50mW

400 – 1100nm

PM30-121: S121B – Silicon Sensor Power Head; 500nW – 500mW;

400 – 1100nm

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

the system menu.
