3.3.3.1 SELECTING BIPOLAR/INDEPENDENT PROTECTION LIMITS
The BOP can be configured to allow the protection limits to be displayed and changed from the
front panel as either a single value that applies to both protection channels or as individual set-
tings for positive and negative protection limits. Selecting Independent protection limits means
that the positive and negative limits are displayed (and can be modified) independently. Bipolar
means that for each protection limit (voltage or current) a single value applies to both the posi-
tive and negative limits; only one value is displayed and can be edited for both ± protection lim-
its.
If the MAX/MIN Protect Settings are not symmetrical when Protect Entry is set to Bipolar, the
protect setting can be adjusted from 0 to the higher protection limit from the front panel; the unit
automatically limits the lower protection limit to the MAX/MIN settings value.
For example, if the unit is in Current mode with +V Protect Max set to 10, -V Protect Max set to
5 and Protect Entry set to Bipolar, setting VPROTECT to 4 from the front panel sets both the
positive and negative protection levels to 4. Adjusting VPROTECT to 6 sets the positive protec-
tion level to 6 but the negative protection level is automatically limited to 5 by -V Protect Max
with no errors or warnings generated.
