are enabled the measurements do not contain high frequency components. To suppress unwanted noise and
harmonic components during measurements, the user can enable the line filter, especially when measuring
small current signals of 1mA or less, to obtain more stable measurement results.
Enabling/disabling Line Filter
1.
Using the [▲] or [▼] key in the SETUP menu to select "Line Filter" (the option is fill with red
shading which means it is selected).
2. Pressing the [ ] or [ ] key to select OFF (disable the line filter) or ON (enable the line filter). The
icon "L.F" will display on the top of the screen when the line filter is enabled.
3. Using the [▲] or [▼] key to select other setting option or pressing the [ESC] key to go back to
the measurement interface.
6.1.3 Frequency Filter
The UTE310's frequency filter is designed for frequency detection circuit, the cut-off frequency is 500Hz. It
is used to accurately detect zero crossing points of synchronized source signals when detecting
measurement intervals. The frequency filter has an effect both on the frequency measurement and on the
measurement interval for detecting voltage, current and power.
Note: The frequency filter is not inserted in the measurement circuit of voltage and current, and even if the
frequency filter is enabled, the measured values contain high frequency components.
Enabling/disabling Frequency Filter
1.
Using the [▲] or [▼] key in the SETUP menu to select "Frequency Filter" (the option is fill with
red shading which means it is selected).
2. Pressing the [
frequency filter). The icon "F.F" will display on the top of the screen when the line filter is enabled.
3. Using the [▲] or [▼] key to select other setting option or pressing the [ESC] key to go back to
