3 MENUS
3.1 INSTANTANEOUS MEASUREMENT MENUS
Voltage (L-N and L-L), current, neutral current, cosØ, power factor, active power, reactive power, apparent power,
THDV and THDI values are shown in instantaneous menu.
Menu are given the name of which is shown in Menu bar.
The values shown on the display is expressed in what phase or phases at the lower left corner of the display
numbers.
Phase Numbers are not displayed at Menus which display avarege, total and other properties of network. In this
case phases are displayed in 2. Level.
Next to each index value unit of respective rows are indicated. It also states that inductive or capacitive phases
are indicated next to the relevant indicators.
Table 1-3 for parameters displayed in the menus.

CAUTION!
When the product is mounted on a panel which consumes power, active power (P) must be positive. If active power is
negative, operator should cross connect k-l leads of the current transformer.
When the product is mounted on a panel which generates power, active power (P) must be negative. If active power is
positive, operator should cross connect k-l leads of the current transformer.
