All sensors are factory calibrated. Some of the calibration parameters are: sensitivity to pressure,
offset, temperature sensitivity and temperature compensation. Calibration parameters will be read
automatically from the internal non-volatile during the start-up of the sensor.
SCP1000 different versions and supported features are presented in Table 1 below.
Table 1. SCP1000 versions.
The SCP1000 pressure sensor has 4 measurement modes plus standby and power down mode. In
all measurement modes, the pressure output word-length is 19 bits and the temperature output
word-length is 14
In the high-resolution measurement mode the pressure is measured continuously with the highest
resolution and the output data refresh rate is typically 1.8 Hz.
In the high speed measurement mode the measurements are performed continuously as well and
the conversion time is shortened at the cost of output resolution. This allows for an increase of the
output data refresh rate up approximately 9 Hz.
In the ultra low power measurement mode the device performs periodic measurements with the
lowest resolution (15 bits) and switches to standby mode between the measurements. In this mode
the updated pressure data is available approximately once per second.
In the low power measurement mode the device stays in standby mode and is ready to perform
single measurement using the selected resolution, 15 bits or 17 bits. After the measurement is
complete and the output data is refreshed, the sensor switches back to standby mode. Average
current consumption in low power mode depends on measurement resolution and trigger
frequency.
Temperature information is available in every measurement mode for each pressure measurement.
