Model 200E Instruction Manual Operating Instructions
The CALS key is used to calibrate the span point of the analyzer. It is recommended that
this span calibration is about 80-90% of full scale of the analyzer’s operating range.
Chapter 7 details all calibration operations, Chapter 1 describes the zero/span valve and
IZS options.
6.3. Calibration Mode
Owing to its importance, calibration is described separately in Chapter 7, EPA protocol
calibration in Chapter 8.
6.4. Setup Mode
The SETUP mode contains a variety of choices that are used to configure the analyzer’s
hardware and software features and to read or configure the internal data acquisition
system (iDAS). For a visual representation of the software menu trees, refer to
Appendix A-1.
NOTE
Any changes made to a variable during one of the following procedures is not
acknowledged by the instrument until the ENTR Key is pressed
If the EXIT key is pressed before the ENTR key, the analyzer will beep, alerting the user
that the newly entered value has not been accepted.
Some of the functions of the SETUP mode are described in separate sections following this
section. In particular, the RNGE function can be found in Section 6.5, the ACAL function in
Section 7.8.
6.4.1. Password (PASS)
The M200E provides password protection of the calibration and setup functions to prevent
unauthorized adjustments. When the passwords have been enabled in the PASS menu
item, the system will prompt the user for a password anytime a password-protected
function is requested.
There are three levels of password protection, which correspond to operator, maintenance,
and configuration functions. Each level allows access to all of the functions in the previous
level.
