[1] Typical measurement rates with auto-zero off, delay = 0, display off, auto range off and math off.
[2] Maximum measurement rates for 0.01 % of ac step. When dc input varies, additional settling delay is required.
[3] For remote operation or external trigger using default settling delay
[4] Speeds available in OutG SW 1.0.700.18 or higher. Note that the measurements rates for RS232 can vary depending on the
baud rate chosen. If the baud rate selected is 115,200, the maximum measurement rate is 711 measurement/s. The LAN bus
has a maximum measurement rate of 963 measurement/s.
