Teledyne Model 300EU manual Initial Calibration, Pre-Calibration Stabilization, Calibration Gases

M300EU	GETTING STARTED
(Addendum to M300EU Manual - P/N 04145)

3.5. INITIAL CALIBRATION

3.5.1. PRE-CALIBRATION STABILIZATION

Before initially calibrating the M300EU it must be allowed to operate for a minimum of 12 hours.

After this stabilization period is complete and just prior to performing the initial calibration, manually initiate an auto-reference measurement by following the instructions in Section 6.4.

3.5.2. BASIC CO CALIBRATION SETUP

NOTE

The following procedure assumes that the instrument does not have any of the available Zero/Span

Valve Options installed.

To perform the following calibration you must have sources for zero air and span gas available for input into the sample port on the back of the analyzer. See Section 3.1.3 of the M300E/EM Operators Manual (P/N 04288) for instructions for connecting these gas sources.

NOTE

All Gas lines should be PTFE (Teflon), FEP, glass, stainless steel or brass

3.5.2.1. Calibration Gases

The information found in Section 3.1.3.2 of the M300E/EM Operators Manual (P/N 04288) is applicable to the M300EU with the following exception:

ZERO AIR

A gas that is similar in chemical composition to the earth’s atmosphere but scrubbed of all components that might affect the analyzers readings, in this case CO and water vapor.

For the M300EU this gas MUST include at least 5% O2 (required for the proper operation of the analyzer’s CO scrubber).

For analyzers without an IZS or external zero air scrubber option, a zero air generator such as the Teledyne Instruments Model 701 can be used.

NOTE

The zero air generator MUST be equipped with a hydrocarbon (HC) & CO scrubber option.

For the Teledyne Instruments M701, this is Option 2B
