RESOLUTION
Except for frequency, temperature, and some special cases of
AC voltage, all functions can operate with 3.5, 4.5, 5.5, 6.5,
or 7.5-digit resolution, or they can default to a setting appro-
priate for the selected integration time. You can program the
resolution parameter as follows:
1. From the normal reading display, press the CONFIG
key and then the appropriate function key to access the
top level of a function configuration menu. For example,
the CONFIGURE DCV menu is displayed as follows:

2. Use the cursor keys ( and ) to highlight RESOLU-
TION and press ENTER. The following typical menu is
shown:
SET DCV RESOLUTION
AUTO 3.5d 4.5d 5.5d 6.5d 7.5d
3. Highlight the desired resolution and press ENTER.
The AUTO selection optimizes the resolution for the present
integration time setting. See Table 3-10 for the default reso-
lutions of the DCV and ACV functions. The default resolu-
tions of other functions are listed in paragraphs 3.4.2, 3.4.3,
and 3.4.5.

Notes:
1. If the DCV resolution is AUTO and the integration time SET-BY-RSLN, the resolution will be 6.5 digits and the
integration time 1.0 PLC.
2. For DCV peak spikes, low frequency RMS, and ACV peak measurements, the integration time setting is ignored.
3. For RMS and average measurements, if the resolution is AUTO and the integration time is SET-BY-RSLN, the res-
olution will be 5.5 digits and the integration time 1.0 PLC.
