“■”表示标配
,
“□”表示选配
“■”
means standard,
“□”
means optional
注:
1
:外置互感器规格时,谐波测量为标配,其余规格均为选配。
2
:默认无功脉冲、时钟脉冲、开关量输出三选一;
3
:有源开关量和第二路通讯二选一;
4
:选配测温功能时
1
、
2
所述选配功能均不可选。
Note:
1:
Harmonic
is a standard while choosing outlay transformer, optional for other situation.
2: Reactive pulse output, clock pulse output and switching output: Choose one of these
three.
3: Active switching, the second communication path: Choose one of these two.
4: Both 1 and 2 cannot be chosen while choosing temperature measurement.
