M300EU	CALIBRATION PROCEDURES
(Addendum to M300EU Manual - P/N 04145)

7.CALIBRATION PROCEDURES

Calibration of the M300EU should be performed according to the procedures described in Chapters 7 & 8 of the M300E/EM Manual - P/N 04288 with the following notes and exceptions:

•Delivering span and zero gases for the higher resolution the M300EU can be difficult. Attention must be paid to the quality of the gasses, the level of contaminants in the gases as well as the history and conditioning of the gas delivery components.

•The analyzer must be continually operating with and adequate flow of sample gas, for 2 hours prior to performing a calibration (12 hours is recommended for the initial calibration).

•DO NOT calibrate the analyzer if it has been turned off or if no sample gas has been flow though it within the last 2 hours.

•After this stabilization period is complete and just prior to performing the initial calibration, force the instrument to perform an auto-reference measurement by following the instructions in Section 6.4.2 .

REQUIRED EQUIPMENT, SUPPLIES AND EXPENDABLES

•Gas lines to and from the analyzer should be PTFE or FEP Teflon, glass, stainless steel or brass only.

•Zero-air source (defined in Section 7.1.2 of the M300E/EM Operators Manual).

•Zero air must include at least 5% O2 (required for the proper operation of the CO scrubber).

•If a zero air generator, such as the Teledyne Instruments M701, is used it MUST be equipped with a hydrocarbon (HC) & CO scrubber option. For the Teledyne Instruments M701, this is Option 2B.

•Span gas source (defined in Section 7.1.3 of the M300E/EM Operators Manual).

•A recording device such as a strip-chart recorder and/or data logger (optional). Data recording device should be capable of bi-polar operation so that negative readings can be recorded.

•For electronic documentation, the internal data acquisition system can be used.

NOTE

If any problems occur while performing the following calibration procedures, refer to Chapter 11 of this

manual for troubleshooting tips.

MANUAL CALIBRATION

The information found in Section 7.2 of the M300E/EM Operators Manual (P/N 04288) is applicable to the M300EU with the following exception(s).

•STEP3 – ZERO/SPAN CALIBRATION

•Set the display to show the STABILITY test function (same as the CO STB function mentioned in the M300E/EM operator’s manual).

•There is no GAS TO CAL step because the M300EU cannot be modified to include the O2 and CO2 sensor packages.

MANUAL CALIBRATION CHECKS

The information found in Section 7.3 of the M300E/EM Operators Manual (P/N 04288) is applicable to the M300EU with the following exception(s).

•Set the display to show the STABILITY test function.
