Multipoint Precision Check 

A multipoint precision check is used to determine the linear response of the instrument across its 
operating range. The instrument is supplied with span gas at multiple known concentrations, 
typically a zero point and at least four up-scale points, spread across the operating range of the 
instrument. The observed concentrations are compared to expected values and the linearity of the 
instrument assessed against local applicable standards. 

Note:

 The instrument is inherently linear and the instrument gain should 

not

 be adjusted at each 

individual point. Non-linearity indicates a problem with the instrument (refer to Section 7). Ensure 

that the instrument has been running for at least one hour before any calibration is performed to 

ensure the instrument’s stability.

 

Several methods for producing multiple known concentrations are available to use, such as 
connecting multiple certified gas cylinders at different concentrations. However, Ecotech strongly 
recommends the use of a dilution calibrator and a certified cylinder of NO at an appropriate 
concentration (typically a cylinder of 40 to 100 ppm NO, balance in Nitrogen).  

1.

 

Connect your calibration system to the 

Calibration Port

 of the instrument (Ecotech recommends 

the Serinus Cal 2000, refer to Figure 45)

2.

 

Generate and record the displayed span concentrations for (at least) five stepped points (of 
known concentrations) evenly spaced across the instruments measurement range (see the 
example below). 

3.

 

Then using a program such as MS Excel, create an X Y scatter plot of expected concentration 
versus the recorded instrument response and use linear regression to calculate the line of best fit 
and the correlation factor (R

2

) – refer to the users local applicable standards. 

Example for an instrument measurement range of 500 ppb: 

a.

 

For the 1st concentration, set the gas dilution calibrator to supply 

400 ppb 

NOx

 

gas to the 

instrument. 

b.

 

Allow the instrument to sample the calibration gas until a prolonged stable response is 
achieved (the amount of time this takes is impacted by the calibration setup). Record the 
instrument response. 

c.

 

Repeat the above steps using concentrations of 

300ppb

200ppb

100ppb

 and a 

Zero

 point. 

d.

 

Graph the results and use linear regression to determine a pass or fail as per your applicable 
local standards. 

𝑦 = 𝑚𝑥 + 𝑐

 

Note:

 To highlight hysteresis errors, it is advisable to run the multipoint check in both 

descending

 

and 

ascending

 order - refer to applicable local standards.
