Guide for Calculator Inputs

Measurement - Select Amps, Volts or Watts
Full Scale Input - Enter full scale value of measurement
Accuracy - Enter % of full scale accuracy. You may need to calculate full scale if accuracy is stated as % of reading.
Output - Select from industry standard typical outputs.
Linearity Offset (optional) - Enter linearity value if stated separately. Many OSI products include linearity in total accuracy.
Electrical Offset (optional) - Enter electrical offset value if stated separately. Many OSI products include electrical offset in total accuracy.
Hysteresis/Magnetic Offset (optional) - Enter hysteresis offset value if stated separately. Many OSI products include hysteresis offset in total accuracy.
Low Temperature - Enter low value temperate operating range. For low temperature range of zero, replace with "0.5".
High Temperature - Enter high value of temperature range.
Temperature Effect/Coefficient - Enter accuracy value of temperature per degree Celsius or Kelvin. If %/°C is not available, please contact factory for assistance.

Please chat with OSI sales representative for assistance with % of full scale temperature calculation.
