4.4.5 Setting up an AUTO-CAL

AUTOCAL is not available for standard configurations of the 4040.

4.4.6 Adjusting the GAIN

The output of the FID is conditioned by an amplification circuit with

3user-adjustable settings:

0)x1

1)x10

2)x100

The resulting signal is converted to a number. Numbers outside the range –262144 to 262143 are unreliable and lead to inaccurate measurements. If the number is outside this range during analysis, the message 'GAIN TOO HIGH' is shown on the 2nd line of the display, and the analyzer is not updated to a new, calculated value. The Gain Too High message may be removed by pressing the ESCAPE key.

The gain has been set at the factory such that the analyzer will work reliably within the prescribed range of operation. The user may change the gain when a different level of sample is to be analyzed.
