Application Note 9505
s
c
Entering s from the Main Menu sends an active low reset
signal to the HI7190 which initializes the HI7190.
Entering c from the Main Menu brings the Change Mode
Menu up. The Change Mode Menu allows the user to
custom con?gure the HI7190 without having to know the
bit positions of the Control Register.
5
Entering 5 from the Change Mode Menu initiates a com-
munication cycle with the HI7190 that invokes the Sys-
tem Negative Full Scale Calibration Mode with a notch
frequency of 10Hz. Other operating parameters are off-
set binary coding, bipolar mode and a gain of one.
Please note, the user should apply the negative full scale
voltage to the HI7190 inputs before issuing this com-

Entering r from the Main Menu brings the Read Menu up.
The Read Menu allows the user to read all registers
without having knowledge of speci?c Instruction Register
address details.
Entering x from the Main Menu exits the program.
The user will be asked a series of questions relating to
HI7190 operation. After completing these questions, the
software compiles the proper data and writes the Control
Register to invoke the desired operating mode. Execut-
ing this command returns the user to the Main Menu.
