Digitizers Specifications
1
Valid within the range of 0°C to 55°C. A zero offset calibration for all channels must be performed if the instrument
experiences a temperature <0°C or >55°C for these specifications to remain valid.
2
Specification is valid when tested at a temperature within ±5°C of the calibration temperature.
3
Amount of error that must be added for each °C outside of ±5°C of the calibration temperature.
