Calibrating the USB-2416
Measurement Computing calibrates the USB-2416 using an NIST-traceable calibration method. This method
stores a correction factor for each AIN range in non-volatile memory on the device at the time of calibration.
Allow a 45 minute warm-up period before calibrating the USB-2416.
Calibration methods
Factory calibration
Measurement Computing's Manufacturing Test department performs the initial factory calibration. You can
return the USB-2416 once a year for a new factory calibration and calibration certificate.
Self calibration
Use InstaCal to calibrate the USB-2416 whenever the ambient temperature changes by more than ±10 °C from
the last self-calibration
You can perform this procedure with thermocouple and voltage inputs connected to the input terminal blocks.
