Teledyne 200AH 用户手册

 

1. 

Preparation 

Make sure a calibration is completed before setting up 
Converter efficiency. 

2. Press 

 

CAL-CONC-CON-NO2 

Enter the expected NO

2

 concentration, then press ENTR. 

3. 

Input a known 
concentration of NO

2

 

calibration gas. 

Allow reading to stabilize for 10 minutes. 

4. 

Press CAL-ENTR 

By pressing ENTR the M200AH will calculate the ratio of 
the observed to expected NO

2

 and will use that ratio to 

compensate future NO

2

 readings. The calculated value can be 

seen by pressing the SET button. 

NOTE:  The CAL button will come on only if the Instrument is 
measuring NO

2

 gas and ratio is between the limits of 0.80 - 1.20. 

5. 

Press EXIT 

EXIT will return instrument to SAMPLE mode. 

 

Method 2. If the converter efficiency is determined by some external means, the value can be 
directly entered. Press CAL-CONC-CON-SET, then key in the ratio and press ENTR, then 
EXIT. 

The following is our recommendation for calibration gasses and equipment for the M200AH. 

Regulator Specifications:  

Ultra high purity, two-stage stainless steel body with stainless steel diaphragms, Tefzel and 
Teflon seats and seals, CGA 660 type. Gauges are 0-4000 psig inlet with 0-100 psig outlet. 

Nitric Oxide Calibration Gas specifications: 

Use NO in nitrogen, EPA protocol 1, NIST traceable (long lead item, order early) for CEMS 
Certification Test gas and acid rain applications.  

Use NO in nitrogen at 80% of calibration range 

 2% for routine calibration. 

Example: Order 80 ppm NO in N2 if calibrating the 0-100 ppm range.
