If a query (?) command results in a “command” or “execution” error, the error value +9.90E+37 is sent
to the output buffer.
Input Message Terminators
In RS-232 mode, all messages sent to the instrument must terminate with either a <lf> character or a
<cr> character. It is also permitted to send both <cr><lf> to terminate a message; the <lf> is ignored.
For IEEE-488 mode, messages can be terminated in one of two ways;
- by sending a <lf> character at the end of the message
- by asserting the EOI line with the last character sent
It is also permitted to combine these, and assert EOI when sending the <lf> character.
Message termination always forces the command path back to the root-level ready for the next
command message.
Input Buffer
The instrument receives messages into an input buffer and only starts executing commands after receipt
of a message terminator. The buffer can store up to 100 characters including separators and terminator.
Sending a new command before the existing command is executed may cause unreliable operation. It is
advisable to query the Status Byte (*STB?) to check on the current status of the microhmmeter before
sending a new command.
Sending a command whilst the microhmmeter is transmitting (following a ? command) may result in
the transmitted response being corrupted. It is advisable to wait for the expected response to be
transmitted before sending a new command.
6.3.2 Configuration & Measurement Commands
Configuration Group
These commands allow the measurement configuration to be set up, but they do not trigger a
measurement.
SENSe:FRESistance:RANGe <range>
Sets the resistance measurement according to the following parameters. The current measurement
is aborted.
