according to the input signal frequency.
AC filter is limited to be used in AC voltage and AC current measurement.
Input Frequency

20Hz to 300kHz
Mid-speed filter (default value)

AC filter selection is stored in volatile memory, and after cutting off power or resetting
remote interface, multimeter will select mid-speed filter (20Hz).
During front panel operation, ensure that the current measurement is ACV or ACI, after
pressing
, press the softkey of Filter (
), and select low-speed filter (3Hz),
mid-speed filter (20Hz) and high-speed filter (200Hz) through
and
, among which
mid-speed filter is default option.
3.1.2 Continuity threshold resistance
When measuring continuity measurement, and if measurement resistance is smaller than
threshold resistance, multimeter will send out a continuous individual tone. Threshold resistance
value can be set as any number from 1Ω to 1000Ω, which can only be adjusted on the front
panel.
Threshold resistance is stored in volatile memory, and after cutting off power or resetting
remote interface, multimeter will reelect 10Ω.
Threshold resistance is set as 10Ω when multimeter leaves factory.
After starting continuity function, press the softkey of Setup (
), and press up, down,
right and left keys and the ENTER key
And
can move the movable and flashing cursor to the position specified by you,
and
and
can edit value size of the current position, with
meaning
increasing and
decreasing.
3.1.3 DC input resistance
Generally, multimeter input resistances at all DC voltage shifts are all set as 10MΩ to lower
noise, and if you want to reduce the effect caused by measurement load error, set the input
resistance at 100mVdc, 1Vdc and 10Vdc shifts more than 10GΩ.
DC input resistance is restricted to be used only in DC voltage measurement.
