3.5.7 DATALOCK
The AC source allows the user to lock data entries, so the pre-defined parameters can be
protected from being modified by an unauthorized person. The user can set DATALOCK on
SETUP functional list (see 3.5). The user also can set DATALOCK = FUNC to operate
“One-key Recall”. It means the user can recall the voltage output setting which stored in the
memory (see 3.8.1
) only need to press 1 - 9 key directly in Main Page.
The procedures of the setting data lock are shown as below:
1. Move the cursor to the command line
of “DATALOCK=”. DATALOCK = OFF_

3.5.8 Is START, Is INTERVAL
Is is the surge peak current of AC source output shown in MAIN PAGE. Is measurement
starts at Is START after output voltage transition. The length of measurement time is Is
INTERVAL. The user can set both on SETUP functional list (see 3.5).
The procedures of setting Is START=10ms, Is INTERVAL = 200 ms, are described as below:
1. Move the cursor to the command line
of “Is START = ”. Is START= 0.0_ ms
2. Press 1 , 0 then press ENTER to
change the value to “10.0”. Is START = 10.0 ms
3. The cursor moves to the command line
of “Is INTERVAL = ” automatically. Is INTERVAL = 50.0_ ms
4. Press 2 , 0 , 0 then press ENTER
to change the value to “200.0”. Is INTERVAL = 200.0_ ms
