FIGURE B-3. PROGRAMMING VIRTUAL MODELS
B.41 [SOURce:]CURRent:PROTection[:LEVel] COMMAND
CURR:PROT
Syntax: Short Form: [SOUR:]CURR:PROT[:LEV]
Long Form: [SOURce:]CURRent:PROTection[:LEVel]
= digits with decimal point and Exponent, e.g., 2.71E+1 for 27.1
Description: Sets overcurrent protection level for power supply. If the value is out of the acceptable overcur-
rent range for the power supply model, error message -222,"Data out of range" is posted in the output
queue. If the power supply output exceeds the current protection level programmed, then the power
supply output is disabled (programmed to 0V, minimum current (see Table 1-1) and the OC bit in the
Questionable Condition status register is set. (See example, Figure B-4.)
B.42 [SOURce:]CURRent:PROTection[:LEVel]? QUERY
CURR:PROT?
Syntax: Short Form: [SOUR:]CURR:PROT[:LEV]? {MIN | MAX}
Long Form: [SOURce:]CURRent:PROTection[:LEVel]? {MIN | MAX}
Return Value: = digits with decimal point and Exponent, e.g., 2.71E+1 for 27.1
Description: Returns value representing current protection level.CURR:PROT? returns value set by
CURR:PROT. CURR:PROT?MAX returns maximum current protection value (see Table 1-2). This
value is determined at the factory and cannot be changed by the user. CURR:PROT?MIN returns the
minimum current protection value (see Table 1-1). (See example, Figure B-4.)
Description: Returns the current value established by CURR:TRIG command. (See example, Figure B-1.)
NOTE: The following example assumes KLP 75-33-1200 with virtual model set for 75V, 16A.
SYST:PASS:CEN 7533 Enables access to the protected commands. NOTE: Password
shown is factory default value for KLP 75-33-1200; values will
vary for other models (see Table 4-1) and can be altered by user.
VOLT:LIM:HIGH? Returns 7.5E1 (75V, virtual model voltage rating).
VOLT:LIM:HIGH 70 Programs virtual model voltage to 70V.
VOLT:LIM:HIGH? Returns 7.0E1 (70V, new virtual model voltage rating).
CURR:LIM:HIGH? Returns 1.6E1 (16A, virtual model current rating).
CURR:LIM:HIGH 30 Programs virtual model current to 30A.
CURR:LIM:HIGH? Returns 3E1 (30A, virtual model current rating).
VOLT:LIM:HIGH? Returns 4 E1 (40V, new virtual model voltage rating). Since model
is limited to 1200W maximum output, programming the maximum
virtual model current to 30A automatically forces the maximum
voltage to be no more than 1200 / 30 = 40V.
VOLT:LIM:HIGH 33 Programs virtual model voltage to 30A. Virtual model limits are now
set to 33V and 30A.
SYST:PASS:CDIS 7533 Disables access to the protected commands (password value must
match).
