Readings with all format options ON 310 230 25 K 50 K
[1] Speeds are for 4 1/2 digits, delay 0, display off, USB data logging off, autozero off, auto-ranging off unless otherwise noted. Use MEAS command
for best I/O performance. RS232 at 115 Kbaud.
[2] Maximum, with default delays defeated
[3] Assumes relative time format (time since start of scan)
[4] 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.
[5] For fi xed function and range, readings to memory, scaling/alarms/autozero off
