RoHS Compliance
Software Installation
This manual contains user information for the FieldMaxII-TOPlaser power/energy meter.
This Coherent product is RoHS compliant.
For complete software installation instructions, refer to the FieldMaxII Software Installation Quick Start Guide (1096359) that shipped with your product.
If that document is unavailable, insert the FieldMaxII CD into your CD-ROM drive. If Autorun is enabled on your system, installation will start automati­cally; otherwise, select Run from the Start menu and then type D:\Setup.exe (substitute the appropriate letter of your CD-ROM drive for D).
U.S. Export Control Laws Compliance
It is the policy of Coherent to comply strictly with U.S. export control laws.
Export and re-export of lasers manufactured by Coherent are subject to U.S. Export Administration Regulations, which are administered by the Commerce Department. In addition, shipments of certain components are regu­lated by the State Department under the International Traffic in Arms Regulations.
The applicable restrictions vary depending on the specific product involved and its destination. In some cases, U.S. law requires that U.S. Government approval
xi
be obtained prior to resale, export or re-export of certain articles. When there is uncertainty about the obligations imposed by U.S. law, clarification should be obtained from Coherent or an appropriate U.S. Government agency.

Safety
SAFETY
Carefully review the following safety information to avoid personal injury and to prevent damage to this meter or any sensor connected to it. Except for replace­able batteries (discussed under Battery Replacement on page 19), there are no user-serviceable parts in the FieldMaxII-TOP meter. For service information, refer to Obtaining Service on page 91.
Use only the power cord specified for the meter. The grounding conductor of the cord must be connected to earth ground.
Do not operate the meter if its panels are removed or any of the interior circuitry is exposed.
Do not operate the meter in wet or damp conditions, or in an explosive atmosphere.
1
Operate the meter only within the specified voltage range.
Do not apply a voltage outside the specified range of the input connections.
Do not operate the meter if there are suspected fail­ures. Refer damaged units to qualified Coherent service personnel.

Quick Start
QUICK START
This section presents a series of mini-tutorials that explains how to connect a sensor to your Field­MaxII-TOP meter and begin taking measurements within minutes. For in-depth information about the procedures introduced in this section, refer to Opera­tion on page 21.
Follow all laser safety procedures. The laser must be blocked or switched OFF before beginning any of the procedures described in this section.
Power to the FieldMaxII-TOP instrument must be OFF before beginning any of the procedures described in this section.
Do not exceed the power/energy density limits of the sensor.

Measuring Average Power With a Pyroelectric Sensor
Connect a pyroelectric sensor to the 25-pin connector. Note: If your sensor
has a BNC plug, you will need to attach a 25-pin adapter.
If Joules mode is currently selected, press the J/W button to select Watts mode.
The following figure shows how to set up a pyroelectric sensor to take an average power measurement.
J (indicates Joules mode) W
(indicates Watts mode)
Press either the Up or Down arrow to manually select the range.
Note: Auto Range is not available for this type of sensor.
Adjust the trigger threshold from 2 to 20% of range. Make sure the trigger threshold is set below the energy you plan to measure.
Take the measurement and observe the result on the display.

Quick Start
Measuring Power With a Thermopile or Optical Sensor
Connect a thermopile or optical sensor to the 25-pin connector.
If Joules mode is currently selected, press the J/W button to select Watts mode.
The following figure describes how to take a power measurement using a thermopile or optical sensor.
J (indicates Joules mode) W
(indicates Watts mode)
Block the beam and then
press the Zero button to set the baseline for your new measurement.
Press the Auto button to turn on Auto Range.
Unblock the beam, take the measurement, and observe the result on the display.

Measuring Energy With a Pyroelectric Sensor
Connect a pyroelectric sensor to the 25-pin connector. Note: If your sensor
has a BNC plug, you will need to attach a 25-pin adapter.
If Watts mode is currently selected, press the J/W button to select Joules mode.
The following figure outlines how to set up a pyroelec­tric sensor to take an energy measurement.

The following figure explains how to take an energy measurement using a thermopile sensor.
Thermopile Sensor
Connect a thermopile sensor to the 25-pin connector.
Press the J/W button to select Watts mode and then find the appropriate watts range by taking a couple of sample measurements. The appropriate range is the lowest range available that does not give an overrange error during the test measurement.

Block the beam and then press the
Press the J/W button to select Joules mode. The Range (Up and Down arrows), Zero button, and Auto button should not be used from this point on. If an overrange error occurs, the range must be adjusted by returning to the Watts mode.
When FieldMax II-TOP is prepared for the first measurement, the TRIG? annunciator displays at the top of the screen. The TRIG annunciator displays during the measurement, showing that the meter is currently integrating the reading. The Zero button should not be pressed between measurements.
Expose the sensor to a laser pulse, take the measurement, and observe the result on the display.
