Teledyne M300EM User Manual

This section contains a variety of information regarding the various methods for calibrating a M300E/EM as well 
as other supporting information.  For information on EPA protocol calibration, please refer to Section 10.   

This section is organized as follows:  

SECTION 9.1 – BEFORE CALIBRATION 
This section contains general information you should know before about calibrating the analyzer.   

This section describes the procedure for checking the calibrating of the M300E/EM and calibrating the instrument 
with no zero/span valves installed or if installed, not operating.   
It requires that zero air and span gas is inlet through the SAMPLE port. 
Also included are instructions for selecting the reporting range to be calibrated when the M300E/EM Analyzer is 
set to operate in either the DUAL or AUTO reporting range modes. 

SECTION 9.3 – MANUAL CALIBRATION AND CAL CHECKS WITH VALVE OPTIONS INSTALLED 
This section describes: 

  The procedure for manually checking the calibration of the instrument with optional zero/span valves 

option installed.   

  The procedure for manually calibrating the instrument with zero/span valves.   
  Instructions on activating the zero/span valves via the control in contact closures of the analyzers external 

digital I/O. 

SECTION 9.4 – AUTOMATIC ZERO/SPAN CAL/CHECK (AUTOCAL) 
This section describes the procedure for using the AutoCal feature of the analyzer to check or calibrate the 
instrument.   

  The AutoCal feature requires that either the zero/span valve option or the internal span gas generator 

option be installed and operating.  NOTE: This practice is not approved by the US EPA. 

SECTION 9.5 – CO CALIBRATION QUALITY ANALYSIS 
This section describes how to judge the effectiveness of a recently performed calibration. 

SECTION 9.6 – CALIBRATION OF M300E/EM ANALYZER’S ELECTRONIC SUBSYSTEMS 
This section describes how to perform calibrations of the M300E/EM Analyzer’s electronic systems, including: 

  Dark Calibration of the optical bench. 
  The pressure and flow sensors. 

SECTION 9.7 – CALIBRATION OF OPTIONAL GAS SENSORS 
This section describes how to perform calibrations of the various optional sensors available on the M300E/EM 
Analyzers, including: 

 The O

2

 Sensor, and; 

 The CO

2

 Sensor.
