UNIdreh LCD, UNIdreh EVU, DR 705
2. Instruction Manual
Accessoires Cat. No. 1133:
3 Test Probes
1 Test clamp
Please observe: Model UNIdreh 700 is also available as set with
three cekon adapters for phase rotation determination for cekon
sockets. Cat. No. 9007.
Please also refer to the our main catalogue including a large
selection of practical and low-cost measuring instruments.
2.0 Operator's Safety
The UNITEST Phase Rotation Indicators are built and tested in
compliance with the safety regulations for Electronic Measuring
Instruments EN 61010-1 and leave our factory in safe and perfect
condition. To maintain this condition the operator has to respect
the safety measures contained in this instruction manual.
The instruction manual contains information and warnings
necessary for safe instrument operation and .
Prior to using the instrument read this instruction manual
thoroughly.
Failure to understand this instruction manual and to comply with
the warnings and references can result in serious and hazardous
injuries or damages.
Attention ! In order to avoid electrical shock: The safety
measures have to be respected when working with voltages
exceeding 120 V (60 V) DC or 50 V (25 V)rms AC. According
to DIN VDE these voltages represent the threshold contact
voltages .
Please note: The values indicated in brackets are valid for
limited ranges such as in hospitals or on farms.

Prior to measurement ensure that the test leads and instrument
are in perfect condition.
The measurement instrument is only to be used for the
specified measurement ranges.
If the operator's safety is no longer ensured the instrument is to
be put out of service and protected against use.
The safety is no longer ensured if the instrument:
• shows obvious damages
• does not carry out the desired measurements
• has been stored for too long under unfavorable conditions
• has been subjected to mechanical stress during transport.
Prior to opening, disconnect the instrument from all measurement circuits.
Any interventions such as fuse replacement may only be
carried out by authorized personnel.
Health and Safety Regulations pertaining to Electrical Systems
must be strictly observed for all tasks.
To ensure correct functioning and long life cycle of the instrument
avoid exposure to direct sunlight.

4.0 Determination of the Rotary Field
The phase sequence of the three phases present determines the
rotary direction of the motor connected. The correct phase sequence
L1, L2, L3 results in a clockwise rotation.
For phase sequence determination connect the three clamps L1,
L2, L3 in any order to the three phase system. LED/LCD-Segment
(3) is illuminated for a clockwise rotary field. If LED/LCD-Segment
(2) is illuminated, exchange
two connections.
Please also refer to table
at the backside of the unit
Correct phase sequence is
displayed even if neutral N
is connected instead of L1,
L2 or L3. Correct phase connection has to be verified by twopole voltage test.
5.0 Maintenance
When using the instrument in compliance with the instruction
manual no special maintenance is required.
5.1 Cleaning
If the instrument is dirty after usage, it is advised to clean it by
using a humid cloth and mild household detergents. Never use
acid detergents or dissolvants.
