4 Operational/Functional Description
The PSR Series spectroradiometers operate as portable field instruments with
onboard data storage and an easy-to-use manual control panel for standalone
operation. Combined with a host PC, the PSR can also be controlled for acquisition in
real time and for retrieval and display of the stored scan data.
4.1 Setup
Battery Pack
To use the PSR Series spectroradiometer install a fully charged battery pack by
inserting it into the battery slot located on the instrument’s operating panel. When
inserting the battery into the battery slot, the four copper tabs on the battery should be
oriented towards the outboard side of the instrument.
IMPORTANT: Never attempt to recharge the battery while it is inserted in the
instrument!
Instrument Power-on Time
Switch the power switch to the ON position. When initially switched on, the PSR
Series disables its membrane switches and displays the message “SEI” on Row 1 of the
LCD display. During this initial power-on period the spectroradiometer is waiting for the
thermoelectric coolers to reach operating temperature before data collection can begin.
This initial power-on period lasts less than a minute; when complete, the message “REF
x.xx” is displayed on the LCD readout.
IMPORTANT: each PSR Series spectroradiometer contains a heat sink built into
the instrument base plate that requires unobstructed air flow for proper
operation. Never rest the instrument on its heat sink while the unit is powered!
