Error Codes
Introduction
While operating the Meter remotely, errors may be detected. Each error is stored in a
buffer that is read in a first-in, first-out (FIFO) order. The error buffer will store up to 16
errors. If another error occurs before any of the first 16 are read from the buffer, the last
error is replaced with -350 (Too many errors). No further errors are stored until the errors
are read from the buffer.
The error buffer is cleared whenever the Meter’s power is removed or a *CLS command
is executed. The *RST (reset) command does NOT clear the error buffer. If no errors are
in the error buffer when it is read, the Meter returns +0 (No error).
Error Codes
Tables 33 through 35 lists the possible error codes and their descriptions.
Table 33. Execution Error Codes and Descriptions
Error Code Error Text Description
-102 Syntax error Invalid syntax was found in the command string. A blank space
may have been inserted before or after a colon in the
command header, or before a comma, or a character such as
#, $, %, or \ was used. This error will occur when the command
header is not formed properly and fails to pass header syntax
rules. Example: SAMP:COUN ,1 or CONF:VOLT#DC
-115 Missing parameter Fewer parameters were received than expected for the
command. One or more parameters were omitted that are
required for this command. Example: SAMP:COUN
-117 Parameter type A parameter within the command does not match a valid type
of parameter for the command specification. For example, a
command expected numeric data and received character data
instead. Example: SAMP:COUNT A
-120 Numberic invalid One or more values in a numeric/channel list parameter is
invalid, e.g. floating point when not allowed.
-124 Numeric value overflow The command contains a parameter of type Numeric Value
that was too large to be stored internally. This occurs if the
value has an exponent greater than +/-43. Example
SAMP:COUNT 1e50
-125 Numeric negative A negative numeric parameter value was entered. Example:
SAMP:COUN -3
