SPEED
The SPEED parameter sets the integration time of the A/D
converter, the period of time the input signal is measured (al-
so known as aperture). It is discussed in paragraph 3.4.1, DC
and AC voltage. Only the differences for 2-wire and 4-wire
resistance are noted here.
The SET-BY-RSLN parameter optimizes the integration
time for the present resolution setting. The defaults for set-
by-resolution integration times of Ω2 and Ω4 are listed in
Table 3-18.

FILTER
The FILTER parameter lets you set the digital filter response
and control its on/off operation. It is described in paragraph
3.9. Only the specifics for 2- and 4-wire resistance are cov-
ered here.
The AUTO parameter for a digital filter optimizes its use for
the present measurement function. The defaults for
automatic filtering of Ω2 and Ω4 are listed in Table 3-19.
