Teledyne 200AH 用户手册

 

There are several ways to check and adjust the calibration of the M200AH. These different 
methods are summarized in the following Table 7-1. In addition, all of the methods described in 
this section can be initiated and controlled via the RS-232 port, see Section 5.7 for details. 

We strongly recommend that NO

X

 SPAN CALIBRATION be done with NO span gas. Since NO 

is unaffected by the converter, both channels can be accurately calibrated. It is also important 
that there be some oxygen in the span gas. Inaccurate calibration of the NO

X

 channel can result 

from calibration gasses containing no oxygen. All calibration gasses must have a dew point of 
< 20

C. 

 

refer to Section 9.2.8 and 9.2.9- Unable to Span or Zero. 

 

1.  Use the SETUP-RNGE menu to set the range the instrument will be operated in. 

2.  If you are using any of the following features, they must be set up before calibration: 

A.  Autoranging or Remote Ranging - See Section 7.8 

B.  Independent Ranges - See Section 7.9 

C.  NO only or NO

X

 only mode, Section 7.6 and 7.7 

Normal calibration assumes that these features are already set up.
