capacity. In the high voltage range, 0 – 300V, the current capacity is one-half (see
Product Specifications, Chapter 2).
During TEST (Output ON), you can switch between high and low voltage modes.
Switching between high/low voltage modes will not affect the voltage setting.
However, there will be a brief interruption of the output (about 20 milliseconds), during
the change.
If your test is unable to tolerate a 20 millisecond drop-out, you should not exercise this
feature.
The system remembers your previously entered limit settings. Thus, the system will
not accept a switching command which would direct operation outside the range limits.
For example, if you have specified a 200V lower voltage limit, the system will not
allow you to switch to the low voltage (150V max) range.
Voltage Display OUTPUT / RESET Button
Use the OUTPUT / RESET button to turn the system output ON or OFF. The LED
above the pushbutton switch will be illuminated when the system is ON.
CAUTION: Before turning the system output ON, please determine that the load
is properly connected, the instrument leads are safely configured, and all
personnel are in a safe location.
Note: Manual voltage adjustments will not automatically change the voltage values
stored in memory locations M1, M2, or M3. To change stored voltage parameter
values, please refer to the Section Program Memory Setting Procedure.
