TRT03

1.1.3 Orderly Practices and Procedures

The Manual shall always be available on the site where TRT03 is used.
Before using TRT03, all personnel (even personnel who only occasionally, or less frequently, work with
TRT03) assigned to operate TRT03 should read the operations Manual.
Do not make any modifications, extensions, or adaptations to TRT03.
Use TRT03 only with the original accessories provided by the manufacturer.
Use TRT03 and its original accessories for the device's intended use only.

1.1.4 Instrument Maintenance

The device should be kept clean in order to prevent excessive cases of dust or other contaminants affecting
its operation. It should be cleaned with water/isopropyl alcohol after any dirt/contaminants are noticed on its
surfaces.

1.1.5 Operator Qualifications

Testing with TRT03 should only be carried out by authorized and qualified personnel.
Personnel receiving any training or instructions on TRT03 should remain under constant supervision of
an experienced operator while working with the test set and the test object.

1.1.6 Safe Operating Procedures

Hazardous voltages of up to 400 V can occur inside TRT03. Therefore, it is not permitted to remove the
protective casing of TRT03.
Hazardous voltages exist on the terminals of TRT03 when the "Red" LED is lit. Never assume
connections are safe even if this LED is off. Switch off and unplug TRT03 before touching connections,
particularly if a fault is suspected.
Before putting TRT03 into operation, check the test set for any visible damage.
Do not operate TRT03 under wet or moist conditions (condensation).
Do not operate TRT03 if explosive gas or vapors are present.
Only external devices that meet the requirements for SELV equipment according to EN 60950 or IEC
60950 should be connected to TRT03 through the serial interface.
Removing theTRT03 protective casing will void the warranty. Any work inside the instrument without
prior authorization from DV Power will also void the
If TRT03 seems to be malfunctioning, please contact the DV Power Support Team (refer to the
"Manufacturer Contact Information" section) after previously checking the "Error Messages" section.
Prior to connecting TRT03, ensure that a transformer (object) to be tested is completely de-energized
and isolated from both the line and the load. Every terminal should be checked and verified before
connecting TRT03. Ground connections may be left in place.
Do not use TRT03 without the extra protective ground cables supplied with TRT03. It must never be
operated in a non-grounded configuration as this may result in an electrical shock to the user or damage
to TRT03. Always establish this connection first before establishing any other connections and remove
this connection as the very last one.
Wherever possible, the outer casing of the transformer under test should also be connected to a safety
earth to prevent the risk of shock. Where this cannot be achieved, adequate precautions should be
taken to prevent access to the transformer (e.g. barriers).
Never exchange connections to the HV and LV sides of the transformer. The "H" connections must
always be connected to the High Voltage side of the transformer. The "X" connections must always be
connected to the Low Voltage side of the transformer. Interchanging any or all of the connections may
result in damage to the transformer or TRT03 and is a significant safety hazard to personnel.
