(RMS Filter): Push to select various filters for the rms converter, allowing
measurements down to the chosen filter frequency without degradation of
accuracy and excessive reading variation. One of the filters is always in circuit.
The 40 Hz filter is the default selection at power on. The filter choices available
are 0.1 Hz, 1 Hz, 10 Hz, 40 Hz, 100 Hz, and 1 kHz. The filter setting determines
the reading rate in ACI. See Specifications. Use the softkeys or the navigational
keys to highlight the selection and then push . Push to return the
Product to the previous menu.
(Select Shunt): This menu opens up a number of submenus that provide
access to specific current shunts and their characteristics. (Measure Setup) of
the ACI Ext Shunt menu provides access to a menu that allows you to change
how measurements are made and what is displayed. See ACI Ext Shunt
Measure Setup Menu.
Select Shunt Submenu
The section explains the Ext Shunt submenu.
(Page Down) and (Page Up): Allows you to scroll through all of the
current shunts stored in the Product.
(Sort by): Allows you to sort by Asset number, Serial number or Max A.
Push to cycle through the choices.
(Delete Shunt): Allows you to delete the selected shunt (indicated by the
darkened circle on the left). A confirmation prompt appears before actual
deletion.
(Manage Shunts): Allows you to edit specific characteristic of the shunt,
as well as adding a new shunt.
Manage Shunts Submenu
The section explains the Manage Shunts submenu, which is similar to the DCI
Ext Shunt submenu mentioned previously.
Push (Edit AC-DC Differences) to open a menu to enter ac-dc
differences of the current shunt. When using Fluke A40B current shunts, enter
the ac-dc differences at each of the frequency points from the calibration
certificate of the respective shunt. When Shunt Corrections is set to ON (under
(Measure Setup)), the calculated current reading is corrected using a
linear interpolation of the ac-differences based on frequency. See the screen
