Resolution setting (digits)
Definition
Resolution is the number of digits a multimeter can measure. Using the Model 2100 multimeter,
you can select the resolution for a specific measurement. The choices for the resolution setting
are: fast 4 1/2, slow 4 1/2, fast 5 1/2, slow 5 1/2, fast 6 1/2, and slow 6 1/2. For higher
measurement accuracy, select 6 1/2-digit resolution; for faster measurements, select 4 1/2-digit
resolution.
The resolution setting applies to all math operations under the selected measurement function.
The selected value is stored in a volatile memory and the setting is only valid for the current
measurement function. You can select different resolutions for different measurement functions.
Default
The default value for resolution is “slow 5 1/2 digit” and the default value will be restored when the
meter has been turned off or after a remote interface reset. The user-selected value for the
resolution setting is stored in a volatile memory and the setting is only valid for the current
measurement function (refer to
Table 2-2).
NOTE The resolution setting for AC measurements is actually fixed at 6 1/2 digits. When you
select a lower resolution, the meter will mask out the extra digits. Your selection of
resolution for AC function will not affect the actual speed or accuracy.
How to set the resolution
The resolution can be set either through the front panel or a remote interface.
