Can I measure Vibration Acceleration using IRD531?

No, Vibration Acceleration cannot be measured using IRD531. You can only measure Vibration Velocity or Vibration Displacement using IRD531. If you wish to measure Vibration Acceleration, then please look at IRD521 or other Accelerometers

How frequently IRD531 needs to be Calibrated?

IRD531 is hermetically sealed and is therefore having an Ingress Protection of IP68. Once made in the factory, it cannot be altered or recalibrated. It can only be checked for proper calibration. ISO recommends checking Calibration of Test and Measurement Apparatus such as Vibration Sensors at a frequency interval of 1 year
