Scientech S200 Vector - Manual (Page 7)

Unpacking and Setup
The indicator and the sensor and accessories are packed in corrugated supports. All packing material should
be saved for future damage free shipments.
Before making any connections, verify that the power (VAC) requirement shown on the power entry module
is compatible with the actual AC power outlet to which the indicator will be connected. The power requirement
of the instrument is easily change by removing the fuse holder and voltage selector which is the center
portion of the power entry module. To remove, insert a screwdriver into the slot on the right side of the
fuseholder and pry out. Slide the voltage selector out, flip over and re-insert into the fuse holder. Plug the
fuseholder back into the power entry module.
Connect the removable power line cord between the power entry module and a grounded AC outlet.
Defeating the ground plug on the line cord will adversely effect the performance of the indicator.
MODELS S200 and D200P
BNC interconnect cables are included with the pyroelectric sensors. Connect the cable between the
pyroelectric sensor and the input and the input connector of the indicator. With the dual channel ratiometer
Model D200P choose either channel A or B. Using an interconnect cable with a different length will
change the capacitance and therefore the joulemeter calibration by a factor of 0.8%/ft. for the 25 mm
sensors and 0.2%/ft. for the 50 mm sensors.
Set the rear panel input switches to the 1 M
Ω and SLOW settings when using the Models P25, SP25, P50,
SP50, PHD25, SPHD25, PHD50, and SPHD50 sensors. Set the input switches to the 1 M Ω and FAST
settings when using the Models PHF25, SPHF25, PHF50, and SPHF50. Set the input switches to the 50 Ω
and FAST settings when using Models P05,.P09, PHF02, PHF05, PHF09.
