4.4.3 Measurement tab options
The Measurement tab of the Configure Instrument dialog box specifies the electrical distribution system, voltage ratios,
nominal frequency and current probe options.
Distribution system:
■
A box listing each of the distribution systems supported by the instrument (see §3.6 for available distribution
systems descriptions).
■
An image is displayed to the right of the list illustrating the connection diagram for the selected distribution
system.
Selection of DC 2-, 3- or 4-Wire implies DC measurements only. Selection of other distribution systems implies AC mea-
surements only.
Nominal voltage and voltage ratio:
■
Set a Voltage Transformer Ratio: When checked, the following fields are enabled (based on the selected
distribution system)
-
Primary: Indicates a level on the primary side of the isolation transformer.
-
Secondary: Indicates a level on the secondary side of the isolation transformer.
