Caution, refer to accompanying docu-
ments.
Protective conductor terminal.
WEEE, Waste Electrical and Electronic
Equipment. Please utilize your local
WEEE collection facilities in the dispo-
sition of this product and otherwise
observe all applicable requirements.
1.2 Safety instructions
Important
Read and comply with the following in-
structions.
Always comply with local safety regula-
tions.
Warning
High voltage/current on input/output terminals.
Do not attempt to service the instrument yourself.
Opening or removing covers may expose you to dan-
gerous voltage. If you attempt to service the instru-
ment yourself the warranty is no longer valid.
Do not use any accessories that are not intended for
use together with the instrument.
Disconnect the instrument from the mains before
cleaning. Use a damp cloth for cleaning. Do not use
liquid cleaners or aerosol cleaners.
Important
Always turn the equipment off before connecting.
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.
Always use safety connecting leads.
Always connect protective earth (ground).
Never leave the instrument unattended while it is
turned on.
Use only approved mains detachable cable set with
the instrument. Main supply cables shall be rated
for the maximum current for the equipment and the
cable shall meet the requirements of IEC 60227 or IEC
60245. Mains supply cables certified or approved by a
recognized testing authority are regarded as meeting
this requirement.

1 SAFETY
Unplug the instrument from the mains supply when it
is left unattended or not in use.
Refer all servicing to Megger authorized personnel.
If you need to return the instrument, please use either
the original crate or one of equivalent strength

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.
