1. To avoid problems with remote programming, it is good practice to routinely clear the buffer (
of a program that performs multiple measurements (
the buffer.
2. FACTory defaults place the instrument in a continuous measurement mode. *RST places the instrument in a non-
continuous measurement mode.
3. READ? triggers and returns 15 readings. These 15 readings are automatically stored in the buffer. See Exercise 4 and 5 for
more information on the READ? command.
4. Statistics for buffer readings are also stored in the buffer. For remote programming,
ings that were stored. It does not return buffer statistics.
(see Section 6 for details).
See Section 4 for details on setting range, digits, rate, bandwidth, and filter.
