Readings
Readings with timestamp
Readings with all format options ON
Speeds are for 4 1/2 digits, delay 0, display off, USB data logging off autozero off unless
otherwise noted. Use MEAS command for best I/O performance. RS232 at 115 Kbaud.
Maximum, with default delays defeated
Assumes relative time format (time since start of scan)
Typical rates assuming lightly loaded PC and limited other traffi c on I/Os .
LAN rates assume use of socket connection; VXI11 will be less.
For fi xed function and range, readings to memory, scaling/alarms/autozero off
