Example
You want to measure in a 3P4W 10 kV system using voltage transformers (10000 V/100 V)
and current transformers (100 A/5 A).
1. Select the "BASIC PARAMETERS" submenu of the "SETTINGS" menu.
Specify the connection type and the ratio of the voltage transformers you are using in the
"VOLTAGE INPUT" menu item.
The ratio of the voltage transformer used can be adjusted only when the setting USE
PTs? is activated.
2. Confirm your entry and press <ESC> to return to the "BASIC PARAMETERS" submenu.
Specify the ratio of the current transformers you are using in the "CURRENT INPUT"
menu item.
3. You can configure the resolution of the current display in the "DISPLAY RANGE" menu
item.
The setting has no impact on the measurement accuracy of the device.
