1.

Press CALS

The M200AU enters the calibrate mode from sample mode.

 

 

This operates the sample/cal and zero/span valves to allow

 

 

span gas to come in through the cal gas inlet port in the rear

 

 

panel. When the CALS button is pressed, the adaptive filter is

 

 

activated. This allows the instrument to respond rapidly to

 

 

concentration changes regardless of their magnitude.

 

 

 

2.

Wait 10 min

Wait for reading to stabilize at span value.

 

 

 

3.

Press SPAN

If you change your mind after pressing SPAN, you can still

 

 

press EXIT here without spanning the instrument.

 

 

 

4.

Press ENTR

Pressing ENTR actually changes the calculation equations.

 

 

 

5.

Press EXIT

M200AU returns to sampling. Immediately after calibration,

 

 

data is not added to the DAS averages.

7.3 Automatic Zero/Span Check

In a typical air monitoring application it is desirable to have the analyzer automatically check (AUTOCAL) its calibration each day. If provided with the proper options, the M200AU provides this capability by using the time of day clock to signal the computer system to check operations. When enabled, the instrument software will automatically check zero and span (AUTOCAL) each day. Optionally, the Z/S cycle can be moved backwards or forwards a fixed time each day.

AUTOCAL setup is covered in Table 6-2.

7.4 Dynamic Zero/Span Calibration

The AUTOCAL system described above can also optionally be used to calibrate the instrument once each 24 hours. Dynamic Calibration is enabled by the CALIBRATE attribute in the AUTOCAL setup menu, see Table 6-2 and Table 7-7. If calibration is initiated using the rear panel contact closures, the DYN_ZERO and DYN_SPAN variables must be set to ON in the VARS menu.

Before proceeding with enabling DYNAMIC Z/S you must setup the AUTOCAL feature. Enabling AUTOCAL is described in Table 6-2. To enable DYNAMIC Zero/Span Calibration:
