3.1.3 Resolution & NPLC Setting
Definition
Resolution is the number of digits a multimeter can measure. You can select the
resolution for a specific measurement. The choices for the resolution setting are: 4
1/2, 5 1/2, 6 1/2. For a faster measurement, you can select 0.001 PLC. For a stable,
higher accuracy measurement, 100PLC is suggested to select. However, the NPLC
setting is used for DCV, DCI,
Ω
2 &
Ω
4 functions only. The
Table 4-1
is the
relationship between the resolution and the intergration time. The lowest PLC on each
digit range is the rapidest selection, such as 0.001 PLC at 4 1/2 digits, 0.2 PLC at 5
1/2 didits and 10 PLC at 6 1/2 digits.
In addition, 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 present measurement functions. You can select different
resolution for different measurement functions.
Default
The default value for the resolution is 6 1/2 digits with 10 PLC and the default value
will be restored when the meter has been turned off or after a remote interface reset.
The manual selected value for the resolution setting is stored in a volatile memory and
the setting is only valid for the present measurement function. Please refer to
Table
1-1
on
page 16.
How to set the resolution
The resolution can be set either through the front panel or the remote interface
operation.
Front Panel Operation
There are two ways to set the resolution. The locations of the buttons are shown with
