    • Calculations in Tiki tracker?

    I'm working on a new project using Tiki Wiki. I want to be able to track calibration records of air sampling instrumentation.

    I'm using a tracker to enter calibration values. Let's say the target value is 50.2 PPM. The instrument shows a response of 48.0 PPM. I'd like Tiki to be able to provide an output of the percentage deviation from the target.

    Target Value = 50.2 PPM (known value)
    Response Value = 48.0 PPM (known value)

    • Calculated Percentage Deviation = 4.38%* (calculated value)


    Can Tiki do this?

    I'm reading through other posts and it looks like this can be done. I'm still working it out.


    This is basically the calculation I want to perform.

    Percent Error = ((Instrument - Reference) / Reference) × 100
    or
    ((f_27-f_24)/f_24)*100
