Calibration Procedure

Teledyne API Model M201E NH3 Analyzer Operator Manual

The first time bottled ammonia is connected to the gas dilution system, regulator/calibrator, the TNx reading may take a number of hours to stabilize.

2.1ZEROING THE ANALYZER

The analyzer can be zeroed by either applying zero air straight to the sample port or through the optional Zero/Span valves, if installed. It is important to remember that if the analyzer was previously sampling ammonia gas, prior to conducting a Zero calibration, it will take some period of time before the zero baseline is reached. The process of zeroing the analyzer consists of delivering dry zero air to the analyzer. The operator then manually zeros the TNx and NOx channels individually through the user interface. The following Tables outline the steps necessary to zero the analyzer.

Important: Each channel (TNx and NOx) must be zeroed individually

1.

Press CAL

The M201E enters the calibrate mode from sample

 

 

mode. Confirm zero gas is flowing past the sample

 

 

port.

2.

Channel Selection

Press TNX or NOx then Press ENTR.

3.

Range Selection

Press LOW or HIGH range then Press ENTR.

 

 

Always calibrate the LOW range, section 3.0 below.

4.

NH3 STB Reading

Wait for the displayed stability reading to fall below

 

 

1.0 PPB. The lower the stability reading the better the

 

 

zero value.

5.

Press ZERO

If you change your mind after pressing ZERO, you

 

 

can still press EXIT without zeroing the instrument.

 

 

You don’t have to enter concentration values. The

 

 

analyzer knows to apply 0 PPB.

6.

Press ENTR

Pressing ENTR actually adjusts the Offset value for

 

 

the selected channel.

7.

Press EXIT

The M201E returns to sampling mode.

8.

Check

All displayed concentrations should read zero. The

 

Concentrations

offset values should be close to zero (-20 to 150 mv)
