CALIBRATION DATA
Model 3022
Figure 1. Calibration Data Sheet
A calibration data sheet similar to the sample shown data for the sensor. In addition to the test data, the
above is included with each unit. The calibration values of calibration and temperature compensation
sheet provides the measured test and calibration resistors are also included.

Accelerometer Selection Guide–Unamplified
• Rstc sets the excitation voltage ramp to compensate the sensitivity
error due to temperature.
• Rset sets the excitation voltage to 5V at 25°C.
• Rzb1, Rzb2 and Rztc1 and Rztc2 calibrate the zero offset and
compensate the offset error due to temperature.
• Rs calibrates the output span.
• Vcc must be >8 VDC.
