 ALC
Enable the ALC function when the DUT is to be driven with constant voltage or constant
current.
ALC : Automatic Level Control
CV : Constant Voltage
CC : Constant Current
Set or check the voltage or current value in advance when specifying the CV or CC.
Otherwise, a signal of unexpected level may be given to the DUT.
When ALC function is enabled, “c” is displayed following the measurement signal level.
・ ・ ・ ・ ・ ・ ・ 1.0000k Measurement frequency Hz
・ ・ ・ ・ ・ ・ ・ 1.00 Vc
・ ・ ・ ・ ・ ・ ・ 1.00mAc
_ SHIFT _ + [ ALC ]
Press the _ SHIFT _ + [ALC] keys to display the ALC setting menu.
ALC:OFF Current setting
0)OFF 1)CV 2)CC 3)Current Options
OFF Disables the ALC function (CV and CC).
CV Enables the constant voltage function.
(Voltage  Measurement signal setting menu）
CC Enables the constant current function. (Current  Current setting menu)
If either CV or CC is enabled, the other is disabled.
Current Displays the current setting menu.
If a setting is made or the EXIT operation is performed, the measurement screen comes
back.
Current: The current setting menu is as follows.
Current: 1.00mA Current setting
0.0010mA to 200mA Range of settable values
The setting resolution is 3 digits (0.1A when < 10A).
If a setting is made or the EXIT operation is performed, one-previous menu comes back.
