FOUR: LOCAL OPERATION
(MODELS PDXX-XXA WITH GPIB IEEE4888.2 &
RS232 INTERFACE ONLY)
INTRODUCTION
These sections contain information on how to locally program the PD Series. Upon powering up, the power
supplies default to local mode operation. All front panel keys may be used to control the power supply.
All operations performed in local mode, may also be performed in remote mode. The unit indicates remote
operation when the RMT’s indicator is shows on the display.
STANDARD OPERATION
This power supply has two basic operating modes: Constant Voltage Mode (CV) and Constant Current Mode
(CC), and two control modes: Local Control Mode (default setting) and Remote Programming Mode. Both
operating modes are available regardless of which control mode is used.
GENERAL INFORMATION
1. The power supplies are able to directly accept programming values of voltage, current and over voltage.
"When a valid input is made, the unit will round off the value to the nearest multiple of the resolution".
If a non-valid input is made, the unit will display " --- OVER --- " and return to previous values.
2. The actual programming voltage and current values via front panel keypad is straightforward. To change
this value, simply use the numeric keys to enter a value. If an error is made, press the "CLEAR" key
and then reenter the correct value. Once the final value is set, press the "ENTER" key. After pressing
the "ENTER" key, the LCD module returns to the metering mode. If a user wishes to recall a setting,
press the function key pertaining to the operation.
For example, to recall a set voltage, press "VOLT" and then press "ENTER" or "CLEAR" key to return
unit to metering mode.
3. To reset any of the output parameters (i.e. VOLT, CURR, OVSET, and VLIST) simply press the desired
function keys, enter the new value and press "ENTER".
