Function Description
A/DTST Display A/D test
Press and hold Enter key to display raw count from A/D converter.
ADOFFS A/D offset calibration (–0.5 mv/V)
Read Caution! statement on page 36 before using this function. Press and hold the setup switch, then press the
Enter key to perform offset calibration.
ADGAIN A/D gain calibration (+4.5 mv/V)
