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 DC and AC current are covered
here.
The AUTO parameter for a digital filter optimizes its use for
the present measurement function. The defaults for
automatic filtering of DCI and ACI are listed in Table 3-14.
RESOLUTION
The RESOLUTION parameter sets the display resolution. It
is discussed in paragraph 3.4.1, DC and AC voltage. Only
the differences for DC and AC current are noted here.
The available resolution on all current functions and types is
3.5 digits to 7.5 digits. If the DCI or ACI resolution is
AUTO, refer to Table 3-15 for the resolution associated with
the integration time.
MEASUREMENT-MODE
This option selects the DC current measurement mode,
either normal or in-circuit measurements. It is programmed
as follows:
1. From the CONFIGURE DCI menu, select
MEASUREMENT-MODE and press ENTER. The
following menu is shown:

Notes:
1. For normal DC current, if the resolution is AUTO and the integration time is SET-BY-RSLN, the
resolution will be 6.5 digits and the integration time 1.0 PLC.
2. For DC in-circuit current, the integration time setting is ignored.
3. For AC current, if the resolution is AUTO and the integration time is SET-BY-RSLN, the resolution
will be 5.5 digits and the integration time 1.0 PLC.
