Command parameters for a rear-terminal adjustment with open circuit
inputs
When calibrating your DMM6500 for a rear-terminal adjustment with open circuit inputs, use the
following command parameters.
Send each command parameter twice. First, send the parameter using the setup command. Second,
send the parameter using the execute command.
The example code below uses the first line of code from the table below. Send all command
parameters using this command.
