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).
Tables 30 through 32 lists the possible error codes and their descriptions.

Error Code Error Text Description
-102 Syntax error Invalid syntax was found in the command string. You may have
inserted a blank space before or after a colon in the command
header, or before a comma, or a character such as #, $, or % \.
This error will occur when the command header is not formed
properly and fails to pass header rules syntax. Example:
SAMP:COUN ,1 or CONF:VOLT#DC
-115 Missing parameter Fewer parameters were received than expected for the
command. You omitted one or more parameters 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, if 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.
