B-20 BHK-MG (OPR) 022014
B.90 SYSTem:SECurity:IMMediate COMMAND SYST:SEC:IMM
Syntax: Short Form: SYST:SEC:IMM Long Form: SYSTem:SECurity:IMMediate
Description: Initializes all NVRAM variable to factory defaults. This includes all memory steps to be set to 0 volts,
minimum Amperes, overvoltage and overcurrent to be set to Eomax+10% and Iomax+10%, respec-
tively, time value to be set to 0.01 Sec. It also initializes the power -up state to have DC Output Control
off (see PAR 3.2.7.4). The calibration password is reset per Table 4-2. See PAR. 3.3.6.2 and Figure 3-
2 for special programming considerations.
B.91 SYSTem:VERSion? QUERY SYST:VERS?
Syntax: Short Form: SYST:VERS? Long Form: SYSTem:VERSion?
Return Value: <int_value>.<int_value> (YYYY.V)
Description: Identifies SCPI Version implemented. Returns SCPI Version number:
YYYY = year, V = Revision number for specified year. (See example, Figure B-7.)
B.92 TRIGger:SOURce COMMAND TRIG:SOUR
Syntax: Short Form: TRIG:SOUR {EXT | BUS} Long Form: TRIGger:SOURce {EXT | BUS}
Description: Sending TRIG:SOUR activates either internal (BUS) or external (EXT) trigger. When the external trig-
ger (ground) is applied to J2 pin 3, output voltage and current are set to previously stored values for
VOLT:TRIG and CURR:TRIG.
NOTE: If INIT:CONT 1 was sent prior to sending TRIG:SOUR EXT, continuous mode is disabled and
unit will wait for INIT:IMM

ERROR MESSAGE
ESR ERROR BIT SET
(SEE PAR. A.5)
EXPLANATION
0,“No error” None No error.
-100,“Command error” Command Error bit 5 Command and data understood, but more information
included which is not recognized.
-102,”Syntax error” Command Error bit 5 First 4 characters recognized, subsequent characters not
recognized.
-103,”Invalid separator” Command Error bit 5 For example, VOLT.PROT received instead of
VOLT:PROT.
-108,”Parameter Not Allowed
Error”
Command Error bit 5 Volt12 sequence, channel number is invalid.
-109,”Missing parameter” Command Error bit 5 For example, VOLT instead of VOLT 21.
-111,”Header separator error” Command Error bit 5 Missing space between volt and value or ; missing.
-113,”Undefined header” Command Error bit 5 First 4 characters could not be identified as legal com-
mand.For example, command VLT instead of VOLT.
-120,”Numeric data error” Command Error bit 5 Expected number but other characters were detected.
-121,”Invalid character in number” Command Error bit 5 Volt 1,500 (comma not allowed).
-123,”Exponent too large” Command Error bit 5 Exponent E+3 or greater is invalid.
-141,”Invalid character data” Command Error bit 5 For example OUTP OFD or OUTP STOP instead of OUTP
OFF.
-150,”String data error” Command Error bit 5 Invalid characters were detected in numeric entry. For
example E.1 instead of E+1 or 4d3 instead of 4.3.
-203,”Command protected” Execution error bit 4 Command only valid in password Cenable state.
