(Measure Setup): Aperture/PLC sets the integration time of the A to D
converter using the navigational keys, much like Measure Setup in DCV. The
choices are:
• Auto
• Auto Fast
• Manual
When you select Manual, use the softkeys and the numerical keypad to edit the
integration time by PLC and Time. The smallest time aperture is 0 seconds with
200 ns increments and has an upper time limit of 10 seconds. The smallest
aperture that can be set by PLC is 0.01. The upper limit is the PLC equivalent of
10 seconds and is determined by the line frequency setting in the Instrument
Setup menu.
Shunt Corrections: When set to ON (Power-on default), the calculated current
reading is based on the external shunt value and the shunt loading from the
10 Mohm input impedance of the Product. Note that if set to OFF, an Instrument
reset (Instrument Setup > Reset Instrument) retains the OFF setting. If the
Product is power cycled, Shunt Corrections is always set to ON.
Select Shunt Submenu
The section explains the Select 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 three choices. Note that the Basic shunt is
always at the top.
(Delete Shunt): Allows you to delete the selected shunt (indicated by the
darkened circle on the left). A user prompt shows before actual deletion.
(Manage Shunts): Allows you to edit specific characteristics of the shunt
as well as adding a new shunt.
Manage Shunts Submenu
The Manage Shunts submenu is explained in this section. Enter the appropriate
information for each of these fields with the navigation keys and numeric keypad.
• Asset number (shown as the first field on the shunt information line of
the main DCI Ext Shunt screen)
• Manufacturer (displayed as the second field on the shunt information
line)
• Model
• Serial Number
• Resistance value: Use the numeric keypad and to input the
resistance value of the shunt, for example from the most recent
calibration certificate. Resistance value is shown as the fourth field in the
shunt information line.
