CALIBRATION

All channels are automatically self-calibrated when the DataPac_USB is initiated and connected to a computer. The self-calibration ensures a linear and precise measurement quickly without the hassle of traditional calibration methods. Limestone Technologies only recommends that examiners manually calibrate the blood pressure channel in the event they are moving between drastically different atmospheric pressures. Examiners can access the easy to use software calibration utility which is built into the FrontEnd for this specific channel.

AUDIO/VIDEO RECORDING

Precisely synchronized video and/or audio dictations can be recorded with any USB or Firewire camera. If you wish to use a composite camera please let our technicians know. Our audio/video recording software is completely integrated into Polygraph Professional Suite which prevents problems associated with OEM software.  At Limestone Technologies we only develop programs that our technicians can support.

PRINTING

Our system supports all of the Pentax and Brother thermal printers for portable real-time continuous printing. Continuous printing is also possible with the Epson “C” series printers. Cut-sheet and banner printing is available for most Windows printers. Examiners also have the ability to pring to jpg. or pdf.
