Functions
The subsequent sections explain the different functions of the Product.
DC Voltage
The DC Voltage function provides 2-wire measurements using the V INPUT HI
and LO Input terminals. Push to use the DC Voltage (DCV) function.
The ranges available are:
100 mV to 1000 V, where the 100 mV to 100 V ranges provide 202 % overrange,
for example, the 1 V range displays up to 2.02 V. The 1000 V range can measure
up to 1050 V.
DCV Menu
This section explains the available DCV menu.
(Range): Each of the dc V ranges can be manually selected or select
Auto to put the Product into Autorange. Make the range selection with the
softkeys or use the navigational keys to highlight the selection and push .
Push to return to the start page of the menu.
(Resolution): DCV has resolution from 4 1/2 digits to 8 1/2 digits. Select
resolution with the softkeys or use the navigational keys to highlight the selection
and push . Push to return to the start page of the menu. The A to D
aperture times associated with each resolution setting are shown in the Product
specifications. See Specifications.
(Z in): DCV has selectable input impedances. Auto provides 1 TΩ for the
100mV, 1V, and 10V ranges, and 10 MΩ for the 100V and 1kV ranges. 10 MΩ
provides 10 MΩ input impedance for all five ranges. Use 1 MΩ for ac/dc transfers
where the ac input impedance is set to 1 MΩ. Make the input impedance
selection with the softkeys or use the navigational keys to highlight the selection
and push . Push to return to the start page of the menu.
(Measure Setup): Sets the integration time of the A to D converter. The
choices are:
• A
