3.5.1 RANGE
The AC source supplies full range of output voltage with four options of 150V, 300V, 600V or
AUTO. Users can set RANGE on SETUP functional list (see 3.5). This parameter controls
relays to parallel (150V RANGE) or series (300V RANGE) power stages to obtain more
current or higher voltage. The 600V range can only work with A615003 fixture. The AUTO
range means that the output range switches automatically between 150V and 300V as
required.
To set the range of output voltage as AUTO as below:
1. Move the cursor to the command line of Range. Range = 300V_
2. Turn the RPG to change the option from
“300V” to “AUTO”, then press
ENTER. Range = AUTO
The AC source will set output voltage as 0 V first in order to eliminate
voltage spike when range changes. Then, it will set output voltage as
set value. It may cause UUT to shut down or get bad if the output is
active, when range changes. Besides, the instrument has AUTO
RANGE function under FIX. MODE. Other LIST, PULSE, STEP and etc
modes are without AUTO RANGE function.
