AUTO_CAL Displays the following message.
Auto Calibration: ON or OFF
Press the arrow key to set auto-calibration ON or OFF. Then, press the

The auto-calibration function automatically starts calibration for all modules every
30 minutes if the output switches of all modules are off for 30 minutes.
NOTE To perform calibration correctly, the measurement terminals should be opened
before starting calibration.
If auto-calibration is enabled, open the measurement terminals or disconnect the
device under test from the measurement terminals after measurement.
ADC_ZERO This function is not available for the Keysight E5260. Available only for the
Keysight E5270B.
Displays the following message.
ADC Zero: ON or OFF
Press the arrow key to set the ADC zero function ON or OFF. Then, press the
Enter
key to make the setup effective, or press the
Exit
key to cancel changing the setup.
The ADC zero function is available for the high-resolution A/D converter (ADC)
and not available for the high-speed ADC. This function measures the internal offset
of the high-resolution ADC and compensates it automatically. The measurement
data displayed on the LCD will be the data after compensation.
NOTE This function is especially effective for low voltage measurements. Disable the
function in cases where measurement speed is more important than measurement
accuracy. This approximately halves integration time.
