4.6 Ammeter &
voltmeter

18. Input marked A. This is the external panel

input to the Sverker ammeter. It is acti-
vated by pressing the button marked A
(item 19) which is located at right beneath
the display window. The indicator lamp
adjacent to this input is lighted to indicate
that the input is activated. F4 6A: Miniature
circuit breaker for the ammeter.

19. Button marked A at right beneath the

display window. This button is used to
transfer the ammeter test point to current
outputs 1, 2, 3 or to select the external
panel input to the Sverker ammeter (item
18). The current value is shown on the
display.

Note!

In the setting mode (MODE activated):
The SEL (blue text) button selects the
menu option that is displayed.

20. Input marked V. This is the input to the

Sverker voltmeter, and it is always acti-
vated. The voltage value is shown on the
display.

21. Button marked HOLD. This button freezes

the prevailing current and voltage values
when the object being tested is tripped or
when generation stops. If tripping does not
occur, the prevailing value is frozen when
Sverker changes to the OFF state. The hold
(freeze) function is toggled on and off by
pressing this button.

When you turn the hold function off, the flashing
trip indicator 15 is reset. Moreover, Sverker senses
the state of timer stop input 14 (STOP), thus making
it possible to respond if a change occurs at this
input. This is valid only while the input is in change
sensing state (b + c, see item 14).

Note!

In the setting mode (MODE activated):
The CHG (blue text) button opens the
displayed menu option so that it can be
changed.
