Tomtec has released a new software revision that offers the user the ability to implement an instrument specific calibration curve - increasing the accuracy to better than 98% over the 450uL range of the instrument.

For details, please contact the TOMTEC Customer Service Department toll free at 1-877-866-8323 - Ext. 370. You will need to supply your Quadra 3 Serial Number and Firmware Revision. The Firmware revision can be found by turning on your Quadra 3 and from the main menu pressing the #5 key - System Settings - there will be two numbers at the lower left corner of the screen - such as:

QBA - 2.2.0

QBB - 2.1.0

We will need both of these numbers to determine what revisions your instrument may need.
