Pyroelectric detector models P25, P50, SP25, SP50, P05, and P09 are coated with a special black absorbing
material which provides a very flat spectral response over a broad wavelength band. Pyroelectric detector
models PHD25, PHDX25, PHDX25UV, PHD50, PHDX50, PHDX50UV, SPHD25, and SPHD50 are coated
with a special high damage absorbing material which provides absorption over a broad wavelength band.
Models PHF25, PHF50, SPHF25, SPHF50, PHF02, PHF05, and PHF09 have a partially absorbing, partially
reflecting chromium coating. The relative spectral responses of these detectors are shown in the following
graph. Please be aware of the absorption differences between the detector’s calibration wavelength and your
operational wavelength. Detailed absorption information is contained in the charts at the end of this manual.

Before using your Vector joulemeter system, please review the energy density formulas given in the chart at the
front of this manual. Familiarize yourself with all of the specifications of the detector models which you are
using. A damage test slide is provided with each P and PHF type detectors, but not with PHD type detectors.
Fire the beam at the test slide before using the detector to be sure you are operating under safe conditions.
Note: The default Group Setting for Vector Pyroelectric Detectors is Group #2. The default
Group Setting for Vector HR Pyroelectric Detectors is Group #3. Either select Group #2,
#3, or configure another Group for pyroelectric detectors and select that Group. For
Group configuration, refer to the Group Settings section.
Note: The automatic trigger threshold of the S310 is 7 % of full scale.
1. To Turn On the Meter:
Note: For the most accurate measurements possible, the S310 should be turned on and warmed
up for 30 minutes.
Press the ON switch located in the rear panel of the meter. The S310 will immediately turn on with its
operational state based on the last used detector Group Setting. If you purchased the S310 with one detector,
this detector’s Group settings will be active and you are ready to take measurements.
If you purchased more than one detector with the S310, you must choose the Group setting for the detector you
are connecting to the S310 as described in step 4. The Group Setting for each detector purchased with your
S310 is shown on page 2.
2. To Turn the Analog Needle On or Off (does not apply to the S310D):
To turn the analog meter on or off, press and keep holding the RANGE button down. Then release after the
meter appears or disappears.
