Notes
------------------------------------------------------------------------------------------------------------
 When the Autocal function is on, the calibration factor is always used to perform the
calibration as a multiplier.
 If the conditions for setting the [Acal] to [ON] shown in 11.18 are not satisfied, the Autocal
function cannot be turned on. However, if any one of the conditions required for setting [Acal]
to [ON] becomes disabled while the Autocal function is on, the ON setting of the Autocal
function is retained.
 If the difference is out of the "Calibration range" shown in 11.18 , the Autocal function is
forcibly set to off.
 If the limiter operates while the Autocal function is on, the Autocal calibration is still applied,
but the limit is applied on the output. If the protection function is activated, the output is
turned off, but the Autocal setting remains on.
 When the output range is changed, the Autocal function is forcibly set to off.
 When the Autocal function is forcibly set to off, the settings saved in the System Setting
Memory are not updated.
 The Autocal function continues to use the calibration factor obtained when Autocal is turned
on until Autocal is turned off. In contrast, the AGC function updates the calibration factor
continuously while the AGC function is on. Therefore, 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. Meanwhile, 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.

 Turning on the Autocal function
1. Turn on the output.
2. Open the AGC/Autocal set window. Following two methods are available.
(a) Shortcut operation:
＋
(b) Push the [Misc] soft-key and select [1: AGC/Auto Cal].
