50 Local Operation
Table 4-1. Controls and Indicators (continued)
Item Description
3 Electronic Load
Status
Annunicators
CC-Indicates the Electronic Load is in the constant current (CC) mode.
Note that Figure 4-1 shows the Electronic Load is in the CC mode (CC annunciator is on).
CR-Indicates the Electronic Load is in the constant resistance (CR) mode.
CV-Indicates the Electronic Load is in the constant voltage (CV) mode.
Tran-Indicates that transient operation is enabled.
Unr-Indicates that the Electronic Load is unregulated (applies only in the CC mode and in the
middle and high ranges of the CR mode).
Prot-Indicates when any protection features (CC, OV, OP, OT, etc.) are active.
Err-Indicates that remote programming error(s) have occurred.
Shift-Indicates that the shift key, bottom key (blue) in SYSTEM group, was pressed.
4 GPIB Status
Annunicators
Rmt-Indicates that the Electronic Load is in the GPIB remote state. In the remote state, the only
front panel key that will function is the Local key.
Addr-Indicates that the Electronic Load is addressed to talk or to listen over the GPIB.
SRQ-Indicates that the Electronic Load is requesting service over the GPIB; i.e., the service
request line (SRQ) is active.
5 SYSTEM Keys
- Returns the Electronic Load from remote (computer) control to local (front panel)
control.
- Displays the Electronic Load’s GPIB address. You can change the address using the
numeric entry keys. You cannot query or change the address remotely (over the GPIB).
(shifted address key) - Displays error codes that resulted from remote programming.
- Used in conjunction with the ENTRY keys to recall the saved settings from the specified
location (Recall 0 through Recall 7). Recall 7 recalls the factory default settings.
(shifted Recall key) - Used in conjunction with the ENTRY keys to save all of the present
settings (mode, current, resistance, voltage, etc.) in the specified register (SAVE 0 thru SAVE 6).
The settings in locations 1 thru 6 will be lost when ac power is cycled. However, SAVE 0 will
cause the settings to be stored in non-volatile memory; and, the next time the Electronic Load is
turned on, these settings will become the power on settings.
(blue shift Key) - Activates shifted key functions (e.g., Error, Save, Slew, etc.). The Shift
annunciator goes on when this key is pressed.
