Calibration With Independent Or Auto Ranges; Calibration In Auto Range Mode - Teledyne 200E Instruction Manual

Calibration Procedures
• Perform the zero/span check. Zero and span checks using the zero/span valve or
IZS option are similar to that described in Section 7.3, except:
On units with an IZS option installed, zero air is supplied to the analyzer through the zero
gas inlet and the same gas stream is used to create span gas internally using the permea-
tion device.
On units with a zero/span valve option installed, zero air and span gas are supplied to the
analyzer through the zero gas and span gas inlets from two different sources.
The zero and calibration operations are initiated directly and independently with dedicated
keys CALZ and CALS.
Note that there is no option to use a dedicated span gas port if the IZS option is installed.
Span gas from a gas tank would need to be supplied through the Sample port or through
one of the auxiliary ports available on the rear panel (with modified internal plumbing),
although the user could modify the plumbing to have the span gas go through the IZS oven
(without the permeation tube installed).
Scroll to the NOX
STB test function.
Wait until NOX
STB falls below
0.5 ppb. This may
take several
minutes.
The value of NOX
STB may jump
significantly. Wait
until NOX STB falls
below 0.5 ppb. This
may take several
minutes.

7.7. Calibration With Independent or AUTO Ranges

Additional considerations apply when calibrating a Model 200E with reporting ranges set to
AUTO (automatic) or IND (independent) mode (Sections 6.5.4 and 6.5.5).

7.7.1. Calibration in AUTO Range Mode

If the analyzer is operated in AUTO range mode, the high and low ranges must be indepen-
dently calibrated. After pressing the CAL, CALZ or CALS keys, the user is prompted for the
range to be calibrated as seen in the zero calibration example below.
