B.29 [SOURce:]LIST:VOLTage:POINts? QUERY
LIST:VOLT:POIN?
Syntax: Short Form: LIST:VOLT:POIN? Long Form: LIST:VOLTage:POINts?
Return Value: (0 to 250)
Description: Identifies the total number of points in a list and the next location to be filled by LIST:VOLT
command. The LIST:VOLT pointer is initially at 0 via *RST or LIST:CLE. For each data point entered
by a LIST:VOLT command the list pointer is incremented If LIST:VOLT:POIN? returns 5, the
LIST:VOLT pointer is at 5 indicating there are 5 data points comprising the list (locations 0 though 4)
and location 5 is the next to be filled. If LIST:CURR has any entries, an error message: -221,”Settings
conflict” is posted in the error queue. Related Commands: LIST:VOLT. (See example, Figure B-2.)
B.30 MEASure[:SCALar]:CURRent[:DC]? QUERY
MEAS:CURR?
Syntax: Short Form: MEAS[:SCAL]:CURR[:DC]? Long Form: MEASure[:SCALar]:CURRent[:DC]?
Return Value: (digits with decimal point and Exponent)
Description: Measures actual current. This query returns the actual value of output current (measured at the out-
put terminals) as determined by the programmed value of voltage and current and load conditions.
NOTE: Current measurement error may be as high as 0.5% for open circuit conditions. (See example,
Figure B-1.)
B.31 MEASure[:SCALar]:VOLTage[:DC]? QUERY
MEAS:VOLT?
Syntax: Short Form: MEAS[:SCAL]:VOLT[:DC]? Long Form: MEASure[:SCALar]:VOLTage[:DC]?
Return Value: (digits with decimal point and Exponent)
Description: Measures actual voltage. This query returns the actual value of output voltage (measured at the out-
put terminals) as determined by the programmed value of voltage and current and load conditions.
(See example, Figure B-1.)
B.32 MEMory:LOCation COMMAND
MEM:LOC
Syntax: Short Form: MEM:LOC Long Form: MEMory:LOCation
int_value = 1 to 40 (memory cell location)
Description: Stores power supply parameters in memory cell specified. Stores voltage, current, overvoltage,
overcurrent values and output on/off state as 0 (off) or 1 (on). Related Commands: MEM:LOC?.
B.33 MEMory:LOCation? QUERY
MEM:LOC?
Syntax: Short Form: MEM:LOC? Long Form: MEMory:LOCation?
int_value: 1 to 40 (cell location)
Return value: ,,,,boolean
val1 = current; val2 = voltage; val3 = overcurrent; val4 = overvoltage,
boolean = 0 (output off) or 1 (output on)
Description: Used to determine contents of 40 memory locations without applying values to KLR output.
Returns the contents of the memory location specified by int_value without affecting KLR output.
Memory locations 1 to 40 are programmed to store settings using *SAV or MEM:LOC. The settings
can also be recalled and applied to the output by *RCL. If a memory cell has not been programmed,
this command returns 0,CURR MIN value,VOLT:PROT MAX value,CURR:PROT MAX value,0 (0
Volts, minimum Amps, overvoltage protection value, overcurrent protection value and output off).
Related Commands: MEM:LOC, *SAV, *RCL.
