STORING/RECALLING POWER SUPPLY OUTPUT SETTINGS
The power supply settings (mode, main channel reference type and setting, protection limit type
and setting and output status) can be stored in one of 99 memory locations for later recall. This
feature is accessible from the front panel by pressing
Saved Settings screen (Figure 3-8). For a description of abbreviations used, refer to PAR.
3.3.8.1 To view previously saved settings refer to PAR 3.3.8.2. To save the power supply set-
tings or modify previously saved settings refer to PAR. 3.3.8.3. To recall saved settings and
apply them to the output refer to PAR. 3.3.8.5.
3.3.8.1
UNDERSTANDING ABBREVIATIONS USED FOR SAVED SETTINGS
The parameters listed in Table 3-8 are displayed, followed by a listing of the first 20 memory
locations, displayed in two rows of ten. Use
navigate to the desired location.
Locations that are not empty show an abbreviated representation of the saved settings. (To see
all the pertinent settings for a particular location, highlight the location, then press
to exit without modifying the settings.)
If either Voltage or Current mode were saved, the main channel setting is listed under the Main
heading followed by V (voltage) or A (current), followed by either f (Output OFF), n (Output ON).
If the reference type is ExtRefLvl (instead of Internal or External), the uppercase V or A is
replaced by lowercase v or a. The protection setting is listed under the Prot heading.
If External mode was saved, the protection setting is followed by C, indicating that the mode
(voltage or current is Conditioned by the external signal applied to pin 2 of the Analog I/O Port
(see Table 2-10).
If the protection setting is followed by a minus sign (–) it indicates that the negative protection
value (displayed) is set larger (absolute value) than the positive protection value (not shown on
the list). Similarly, if the protection setting is followed by a plus sign (+) it indicates that the posi-
tive protection value (displayed) is set larger than the negative protection value (not shown on
the list).
If Main channel reference was saved as External, EXT is listed under the Main heading. In this
case the main channel reference uses the external voltage applied to pin 11 of the Analog I/O
Input Port (see Table 2-10).
