Teledyne API Model 201A NH3 Analyzer Instruction Manual, 04689, Rev. B1

2.1.1 Zero/Span Calibration with Z/S Valves or ECO Option

The zero gas enters through the zero gas inlet port on the rear panel. Make sure that the umbilical cord that makes the control connections between the analyzer and the converter is connected (see Figure 2 below). The zero gas valve can be activated by a variety of methods discussed in Section 7 of the M200A manual. The example below will use the front panel keyboard to activate the valves.

1.

Press

The M201A enters the calibrate mode from

 

CALZ

sample mode. The zero gas is supplied

 

 

through the zero air inlet port on the rear panel.

2.

Wait 20

Wait for reading to stabilize at zero. If the

 

min

instrument has recently been exposed to high

 

 

levels of NH3, you may need to wait up to 2

 

 

hours for the instrument to return to zero.

3.

Press

If you change your mind after pressing ZERO,

 

ZERO

you can still press EXIT here without zeroing

 

 

the instrument.

4.

Press

Pressing ENTR actually changes the

 

ENTR

calculation equations.

5.

Press

M201A returns to sampling. This switches the

 

EXIT

ZS valves so that sample gas is coming in the

 

 

sample port on the rear of the instrument.

 

 

Immediately after calibration, data is not added

 

 

to the DAS averages.

 

 

 

Since the zero gas concentration is defined as 0 ppb, it is not necessary to enter the expected zero value.

The expected value of the span gas is entered into the instrument by the following procedure.
