Limit Key
The power supply works in 2 modes:
ØØ Limit mode
ØØ Normal mode
In limit mode limit values of voltage and current are displayed. These are the
programmed values (from the front panel or over the remote interface).
Limit key is used to get the power supply to limit mode. In this mode, lmt
indicator and limit values for voltage and current will be displayed.
In limit mode, limit values can be adjusted by turning the knob. To adjust
values in limit mode, > < keys must be used to select the digit you want to
adjust. The selected digit has the cursor underneath it. To increase / decrease
value of digit, knob must be turned.
After setting the limit values, by pressing Limit key, the power supply returns
to normal mode. It also returns to normal mode after several seconds (display
time-out) with no action.
In normal mode, voltage and current values measured at the output terminals of
the power supply are displayed.
When you turn on the power supply, the cursor is placed underneath the voltage
value (units digit). To pass from voltage value to current value Volt/Amp key
must be used. This key toggles between voltage value and current value.
