SAVE
Press the SAVE button to save the current setup to memory. This enables you to power cycle the indicator
and return to the same indicator setup. The SAVE button must also be pressed after a calibration.
OPERATING PROCEDURES
Joulemeter sensor 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. The PHF25, PHF50,
SPHF25, SPHF50,PHF02, PHF05, and PHF09 have a partially absorbing and partially reflecting chromium
coating. The relative spectral responses of these sensors are given in Figure 1.

Before using you Vector joulemeter system, please review the energy density ratings given in the chart on
page 2, which apply to all models of Vector pyroelectric joulemeter sensors. Familiarize yourself with all of the
specifications of the sensor models which you are using (given at the front of this manual).
HR Battery Installation
A 9 volt alkaline battery comes installed with all HR Series detectors. Always select the OFF position of the
power switch when the detector is not in use to spare the lifetime of the battery. Replace the battery when
the low battery LED indicator lights up.
