Use the < > keys to select the range: 01, 02, or 03. Then press Enter .
Gas Use: SO2
Range: Ø — 10%
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
Δ∇ 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 ACTU-
AL concentration of the span gas being simulated.
If the OUTPUT value shown is not correct, the linearization must be
corrected. 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 6000B 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:
1. Press the System key to start the System function
