Notes


If the output voltage setting is out of the "Operation range" shown in
9.16
, the calibration
is not performed while the AGC function setting remains on and the icon is still
displayed.

If the difference is out of the "Calibration range" shown in
9.16
, the AGC function is
forcibly set to off, and the icon disappears.

If the limiter operates while the AGC function is on, the AGC calibration is not performed.
When the limiter operation is completed, the AGC calibration restarts. If the protection
function is activated, the output is turned off, but the AGC setting remains on.

The on/off setting of the AGC function is kept even if the output range is changed.

When the AGC function is forcibly set to off, the settings saved in the System Setting
Memory are not updated.
 The AGC function updates the calibration factor continuously while the AGC function is
on. In contrast, the Autocal function continues to use the calibration factor obtained when
Autocal is turned on until Autocal is turned off. Therefore, in the AGC function, the
output voltage is calibrated properly even when the load is fluctuated, but there is the
response time to reflect the update of the calibration factor. Meanwhile, in the Autocal
function, the output voltage may not be calibrated properly when the load is fluctuated,
but once Autocal is turned on, there is no response time needed for calibration.
