Operational Modes

ZSSC3154 provides several AOUT2 output behaviors based on the

EEPROM settings.

The AOUT2 output is selected by the “Mode” fields

under “Out2” (see Figure 3.10 and Table 3.1). The AOUT1 output always

represents the calibrated sensor signal. Digital filter settings can also be

adjusted in this section with the LPFAVRG and LPFDIFF fields for each

output in the range of 0 to 7. For more details refer to the ZSSC3154

Functional Description.

Note: It is recommended that both outputs have the same filter settings for

LPFAVRG and LPFDIFF.

Calibration Window

The “Sensor – Calibration” dialog is used to perform a calibration of the ZSSC3154 with either the SRB or

the user’s sensor module.

This screen can be accessed by either clicking on the

icon or selecting “Calibration” on the top menu.

Section 4 gives an example calibration using the commands on this screen:
