3.1.4 Resolution

Resolution is expressed by digits which can be measured or displayed by multimeter, which can
be set as 4, 5 or 6 integrated digits, and add [1/2] single units represented by [0] or [1]. If it is
expected to increase measurement accuracy or control noise, please select 6 1/2 digits, while to
increase measurement speed, please select 4 1/2 digits.
Resolution setting is suitable for all the measurement functions. Resolution of math operation
(zero-digit value, limits, dB, dBm and limit test) is the same as that of measurement function.
Corresponding relation between resolution digit and integral time (within power period) is as
follows:
Resolution
High speed 4 1/2
Low speed 4 1/2
High speed 5 1/2
Low speed 5 1/2
High speed 6 1/2
Mid speed 6 1/2
Low speed 6 1/2
Resolution is stored in volatile memory, and after cutting off power or resetting remote

interface, multimeter will set resolutions of all the measurement functions as mid speed 6
1/2.
During DC continuity and diode test, resolution is fixed as high speed 5 1/2.

During DC and resistance measurement, change of resolution digit number does not only

change multimeter resolution, but also integral time, namely, during one certain
measurement, input signal period in sampling of simulation/digit converter (A/D Converter)
on multimeter. Meanwhile, please refer to the chapter of [Integral Time].
During AC measurement, actually resolutions are all fixed as 6 1/2 digits.

During ratio measurement, resolution refers to the resolution of receiving signals at input

terminal.
During front panel operation, there are two methods to change resolution.
