Since the PLT is often used as a DMM or signal generator, it may be desirable to have a mode in which is can be calibrated on a periodic basis without opening the housing.

  Full calibration is not implemented yet but we have implemented a calibration offset. (See https://docs.pltcloud.com/TestPlanReference#calibration)
  
  
  Example usage:

  title: "ICT test plan"
  calibration:
  - impedance: -100Ohm
    voltage: +20mV # Default for all voltage channels
    voltageDATP01: +40mV
    voltageMUX2: +20mV
    voltageMUX3: +30mV
    currentVARV: -20mA
  - ppc: 39c8db # Additional offsets for this PPC
    impedance: +120Ohm
    voltageDATP08: -10mV
    current5V: +100mA
  suite:
  - title: Impedance Measurement
    steps:
    - command: mux 0 RATP02
    - command: mux 1 RATP17
    - command: mux 2 RA
    - command: mux 3 RVREF
    - command: short 0 2 set
    - command: short 1 3 set
    - command: measure impedance 10-20Ohm

  Could also be desirable to take a measurement at the start of a test plan and use this as a calibration offset.

  It would also be nice to be able to auto-calibrate the VARV output, given that the voltage measurement is a lot more accurate than VARV appears to be.

  It would be nice to have ISO-13485:2016 standards
