1 Start-up guide
1.1 Safety and operational considerations
ÌThis document is a supplement to the Instruction manual!
ÌWarning on the instrument means »Read the Instruction manual with special
care to safety operation«. The symbol requires an action!
ÌRead the Instruction manual carefully, otherwise use of the instrument may be
dangerous for the operator, for the instrument or for the equipment under test!
ÌIf the test equipment is used in manner not specified in this user manual the
protection provided by the equipment may be impaired!
ÌDo not use the instrument and accessories if any damage is noticed!
ÌConsider all generally known precautions in order to avoid risk of electric shock
while dealing with hazardous voltages!
ÌDo not use the instrument in supply systems with voltages higher than CAT II
300 V!
ÌUse only correctly earthed mains outlets to supply the instrument!
ÌUse only standard or optional test accessories, supplied by your distributor!
ÌInstrument servicing and adjustment is only allowed to be carried out by a
competent authorized personnel!
ÌIn case a fuse has blown follow the instructions in user manual to replace it!
ÌHazardous voltages can exist inside the instrument. Disconnect all test leads,
remove the power supply cable and switch off the instrument before opening the
battery compartment.
ÌInstrument contains rechargeable Ni-Cd or Ni-MH battery cells. The cells should
only be replaced with the same type as defined on the battery placement label or
in this manual. Do not use standard alkaline battery cells while power supply
adapter is connected, otherwise they may explode!
ÌIf a test code with an earth bond test current not supported by the instrument is
selected the SigmaPAT instrument will automatically perform the earth bond test
with lower test current (200 mA or 10 A). The operator must be competent to
decide if performing the test with lower test current is acceptable!
ÌIt is advisable not to run tested devices with load currents above 13 A for more
than 15 minutes. Load currents higher than 13 A can result in high temperatures
of main supply connector and fuse holders!

1.3 Warnings, messages and symbols
1.3.1 Warnings and messages
Mains voltage is not
correct or PE not
connected.
Check mains voltage
and PE connection!
Warning for improper supply voltage condition. Possible
causes:
- No earth connection or other wiring problem on
supply socket.
- Incorrect mains voltage.
Determine and eliminate the problem before proceeding!
Warning:
- The instrument must be earthed properly!
Warning!
Instrument is
connected to an IT
earthing system or PE
not connected.
Supply voltage warning. Possible causes:
- No earth connection,
- Instrument connected to an IT earthing system.
Warning:
- The instrument must be earthed properly!
No mains voltage.
Connect PAT to mains
voltage.
Instrument not connected to the mains supply voltage.
For some measurements like differential / touch leakage
tests, PRCD / RCD tests and active polarity, operating the
instrument from mains voltage is required.
Connect the instrument to the mains voltage and start
selected test again.
L – N resistance too
high (>30 kΩ)!
Check fuse and
switch.
Are you sure to
proceed (Y/N)?
An excessively high resistance was measured in the fuse
pre-test. Indication means that tested device has too low
consumption or is:
- Not connected,
- Switched off,
- Contains a fuse that has blown.
Select YES or NO with Y or N key.
Resistance L – N low!
Are you sure to
proceed (Y/N)?
A low resistance of the device under test (DUT) supply input
was measured in the pre-test. This means that it is very
likely that an excessively high current will flow after applying
power to the DUT. If the high current is only of short duration
(caused by a short inrush current) the test can be performed,
otherwise not.
Select YES or NO with Y or N key.

MI 3310 SigmaPAT Instrument description
8
Resistance L – N too
low!
Are you sure to
proceed (Y/N)?
An extremely low resistance of the DUT supply input was
measured in the pre-test. It is likely that fuses will blow after
applying power to the DUT. If the too high current is only of
short duration (caused by a short inrush current) the test can
be performed otherwise it must be stopped.
Select YES or NO with Y or N key.
It is recommended to additionally check the DUT before
proceeding with the test!
Leakage LN-PE high!
Are you sure to
proceed (Y/N)?
Dangerous leakage current (higher than 3.5 mA) will flow if
power would be connected to DUT.
Select YES or NO with Y or N key.
Proceed with testing only if all safety measures have been
taken. It is recommended to perform a thorough earth bond
test on the PE of the DUT before proceeding with the test.
Leakage LN-PE too
high!
Are you sure to
proceed (Y/N)?
Dangerous leakage current (higher than 20 mA) will flow if
power would be connected to the DUT.
Determine and eliminate the problem before proceeding!
Leakage LN-PE or
EB/S too high!
Are you sure to
proceed (Y/N)?
Dangerous leakage current (higher than 20 mA) would flow if
power were connected to the DUT.
Select YES or NO with Y or N key.
Proceed with testing only if all safety measures have been
taken.
It is recommended to perform a thorough earth bond test on
the PE of the DUT before proceeding with the test.
External voltage on
test socket too high!
DANGER!
- Voltage on mains test socket or LN/PE terminals
is higher than approximately 25 V (AC or DC)!
Disconnect the DUT from the instrument immediately and
determine why external voltage was detected!
External voltage on
EB/S too high!
DANGER!
- Voltage on test probe (EB/S) is higher than
approximately 25 V (AC or DC)!
Disconnect the test probe from the DUT and determine why
external voltage was detected!
Test was skipped for
safety!
Instrument skipped the required test because of a failed
previous test.

1.4 Battery handling
ÌWhen replacing battery cells or before opening battery/fuse compartment cover,
disconnect any test leads/accessory connected to the instrument and switch off
the instrument. Hazardous voltage can exist inside the instrument!
ÌInsert all cells correctly! If this is not performed correctly, the instrument will not
operate and the battery could be discharged.
ÌIf the instrument is not used for a long period of time, remove all of the battery
from the battery compartment to protect the instrument from leakage.
ÌAlkaline or rechargeable Ni-MH battery cells (size C) can be used. The operating
hours are given for cells with a nominal capacity of 4500 mAh.
Do not recharge alkaline battery cells! The battery will begin charging as soon as the
instrument is connected to the mains supplv voltage. The in-built protection circuits
control the charging procedure.

Note:
ÌOnly use the power supply adapter delivered from manufacturer or distributor of
the test equipment to avoid possible fire or electric shock!
