  • 1.  Calibration - Data Sheet Template for Calibrating a Resistor

    Posted 21 hours ago

    I need some help understanding how I would configure a Data Sheet Template for calibrating a resistor. This is the first simple use case for calibration that I am configuring for our Cal Shop. This is a 250Ω resistor and they just check to make sure it is 250Ω ±0.03%. They will adjust the resistance if needed and retire the asset if it cannot be adjusted into spec. This resistor will be used as M&TE for other calibration work orders.

    I've tried several different methods of configuring the data sheet, but it seems I have to have an Input and an Output in order to specify a Tolerance. I understand how this is useful for pressure transducers and the like where the input might be PSIG and the output mA, but I don't understand what I should be entering for a single measurement.

    Dear Wesly, 

    I may suggest to use function checks with a True / False result. Used generally for external calibrations for that we do not have measurements.

    Wes,

    I setup a sheet/Asset Function with the Input range being 240 - 260 Ohms, with the Range Limit -0.0075 to 0.0075 EU ohms. Then the Tolerance is checked on the Output and the Output range is also 240-260 ohms. Tolerance 1 is -0.0075 to 0.0075 EU and If exceeded is Fail. On the Cal Point record is 250 nominal and desired is 250.

    While in hindsight I might have messed up the 0.03% to EU, the form seems to accept values/reacts with Pass/Fail as I expected once on a work order.

    (I am using MAS Manage 9.0, not Maximo 7.6)
