Press Enter again.

Algorithm setup:

VERIFY SET UP

Select and

Enter

VERIFY to check whether the linearization has been

accomplished satisfactorily.

Dpt INPUT OUTPUT

Ш Ш.ШШ Ш.ШШ

The leftmost digit (under

Dpt) is the number of the data point being moni-

tored. Use the

∆∇ keys to select the successive points.

The

INPUT value is the input to the linearizer. It is the simulated output of

the analyzer. You do not need to actually flow gas.

The

OUTPUT value is the output of the linearizer. It should be the ACTUAL

concentration of the span gas being simulated.

If the

OUTPUT value shown is not correct, the linearization must be correct-

ed. Press

ESCAPE

to return to the previous screen. Select and Enter

SET UP

to Calibration Mode screen. (set-up will not work without a PC being connected
to the analyzer)

Select algorithm

mode : AUTO

There are two ways to linearize:

AUTO and MANUAL: The auto mode

requires as many calibration gases as there will be correction points along the
curve. The user decides on the number of points, based on the precision re-
quired.

The manual mode only requires entering the values for each correction

point into the microprocessor via the front panel buttons. Again, the number of
points required is determined by the user.

3.3.7 Digital Filter Setup

The 6000A has the option of decreasing or increasing the amount filtering

on the signal. This feature enhances the basic filtering done by the analog circuits
by setting the amount of digital filtering effected by the microprocessing. To
access the digital filter setup, you must:
