Calibrating The Ares-G2 - TA Instruments ARES-G2 Getting Started Manual

Calibrating the ARES-G2

To obtain accurate experimental results, calibrate the ARES-G2 when you first install it. For the best
results, you should recalibrate periodically. The calibration procedures that you need to perform will vary.
See the chart below for a general guide to types of calibration. For details on how to perform that cali-
bration, refer to the online documentation accessed through the TRIOS software.
The table below lists required calibration tasks and the recommended calibration interval for each task.
The table also shows when certain calibrations must be performed following repairs.

This section provides a brief description of each type of calibration. For the procedures needed to perform
the calibration, refer to the online help accessed through the TRIOS software.
