memory to the GPIB output buffer, they are converted to the overload number
for the specified output format. (See the
reading assuming a certain scale factor. This scale factor is based on the
present measurement function, range, A/D setting, and enabled math
operations. When you recall a reading, the multimeter calculates the scale
factor based on the present measurement function, range, A/D setting, and
enabled math operations. It then multiplies the scale factor by the stored
reading and sends the result (recalled reading) to the display or the output
buffer. Therefore, always ensure that the multimeter's configuration is the
same when storing and recalling data in the SINT or DINT format.
