Warning: You must exercise caution when using HD detectors. They exhibit spectral reflection of
between 7% and 18%, of the input power, back out of the aperture. Please refer to 
Figure 1 to determine the reflectance for the wavelength you are measuring. These 
detectors should be treated as a partial mirror or any other type of reflective optic and 
the appropriate caution level observed, especially at the CO
2
wavelength.

Note: HD calorimeters might show “beam” marks on the absorbing surface. These marks are 
characteristic of the material and do not affect the performance of the calorimeter. Do not rub off 
or remove the marks. Polishing or cleaning the absorbing surface might change the performance 
of the calorimeter. 
 
Please see the table at the end of this manual for specific absorption vs. wavelength information.

EQUIREMENTS
:
This product is intended for indoor use at altitudes up to 2000 meters, Pollution Degree 2 in accordance with 
IEC 664 and transient overvoltages according to Installation Categories (Overvoltage Categories) II. Note that 
each of the above detectors will not pass the IEC 801 Publication, Part 3, Radiated Electromagnetic Field 
Requirements. The system, meter and detector, is designed to measure radiation within the test's radiation band. 
The detectors were held outside the radiated electromagnetic field during this test. It is up to the user to be 
aware of RF fields present during measurements and their effects if any on those measurements.

:
The calorimeter and accessories are shipped in custom packing materials. All packing materials should be 
saved for future damage free shipments. 
 
A ½” diameter mounting post is included. Screw the post into one of the mounting holes in the body of the 
calorimeter. Mount the post to your optical bench or working surface. An optional mounting base, Scientech 
Model 301-019, is available for this purpose. 
 
A 3 meter mini DIN interconnect cable is also included. If you are using a Scientech indicator, connect the 
calorimeter to the indicator with the interconnect cable. Follow the detailed set up instructions that are in the 
indicator’s instruction manual. If you are not using a Scientech indicator operating requirements are contained 
in this manual.
