2 INTRODUCTION
The SVERKER 650 is a rugged instrument but it still
should be handled with care.
The relay testing unit is electrically fully isolated in all
measuring ranges, except for the mains output. The
set of resistors is not connected with the rest of the
relay testing unit set.
When current measurement is crucial; use an exter-
nal instrument with a more accurate resolution. The
external instrument can be connected to the built-in
current transformer (terminal W2).
Relays with non-linear impedance can cause distortion
of the current. This can be restrained by connecting
a resistance (as high as possible) in series with the
primary winding of the output transformer (terminal
W1).
The output transformer is protected by a thermal
contact. If the thermal contact trips, the display of the
timer will go out. The thermal contact will be reset
automatically when the temperature drops.
The output (U6) is provided with over-current protec-
tion, that will break the circuit in case of overload.
The protection is reset if (S2) is switched off in aprox.
30seconds.

4 OPERATING INSTRUCTIONS
4Operating instructions
4.1 General
Important
Read the manual and comply with the
Safety instructions, see page 5, before us-
ing SVERKER 650.
Always comply with local safety regula-
tions.
The terminal of the current transformer
shall always be short-circuited when
current is flowing from the instrument,
either through the short-circuit clamp or
through an external ammeter..
4.2 Testing current relays
1] Set the variable transformer in position “0”.
2] Connect the circuit, use output terminals
0-10 A (85 V), 0-40 A (25 V) or 0-100 A (10 V).
3] Increase the current to the operating value
using the variable transformer.
4] Check the current on the ammeter or exter-
nal instrument during the test.

BA0143KE ZP-BA01E SVERKER 650 11
4 OPERATING INSTRUCTIONS
4.3 Testing voltage relays
1] Set the variable transformer in position “0”.
2] Connect the circuit. Output terminals 0-250V,
or at a voltage below 10 V, output terminals
0-100 A. If you need a higher CA-voltage,
terminals 0-250 V can be connected in series
with the mains output terminals. When test-
ing DC-voltage relays, use terminals
0-350 V=.
3] Increase the current to the operating value
using the variable transformer.
4] Check the current on the ammeter or exter-
nal instrument during the test.
Use an external measuring instrument for
better accuracy.
4.4 Testing power relays
1] Set the variable transformer in position “0”.
2] Connect the circuit. Output terminals 0-10 A,
0-40 A or 0-100 A are used for the current
coil. Use an external measuring instrument
for better accuracy.
When testing reactive relays, the current coil
is to be connected in series with the built-
in 10 F capacitor that will give a 90° phase
shift.
The voltage coil is to be connected directly
to the 110 V CA terminals or across the set of
resistors used as a voltage divider.
3] Increase the current to the operating value
using the variable transformer.
4] Check the current on the ammeter or exter-
nal instrument during the test.
Note Shift polarity of the voltage or current if func-
tion has failed to appear.

12 SVERKER 650 ZP-BA01E BA0143KE
4 OPERATING INSTRUCTIONS
4.5 Time measurement
1] Connect the time measuring circuit to poten-
tial free terminals or DC voltage 3-350 V.
Note If the polarity is shifted the timer does not
stop. The timer is independent of mains
frequency.
2] When the timer is stopped, the circuit is bro-
ken and the yellow signal lamp is lit.
3] For continued measuring, the main switch
(S1) first has to be reset in position ”OFF”.
If the tripping circuit is connected and the
switch is set in position “ON”, the yellow
signal lamp is lit when the operating value is
obtained without breaking the current.
Note The timer can be started externally by a make
at terminal (W3). The switch (S1) should then
be in position “ON+TIME” or “OFF+TIME”.
When using the timer internally, the terminal
(W3) has to be short-circuited.
4.6 Time measurement
of over-current and over-
voltage relays
1] Connect the current and tripping circuits.
2] Set the switch in position “ON”.
3] Increase the current/voltage to 25-50% over
the operating value and let the variable
transformer be in that position.
4] Reset the switch to position “0”.
5] Set the changeover switch for time measure-
ment in position make/break
6] Set the switch to position “ON + TIME”.

BA0143KE ZP-BA01E SVERKER 650 13
4 OPERATING INSTRUCTIONS
4.7 Time measurement of
under-current and under-
voltage relays
1] Connect the tripping circuit.
2] Set the changeover switch for time measure-
ment in position make/break.
3] Set the switch in position “ON”.
4] Increase the voltage/current until the relay
picks up.
5] Then set the switch in position “OFF + TIME”.
