The phase-sequence indicator TRITEST

®

 control is a 

measuring instrument for testing the phase sequence 

of three-phase mains (subdistributions, sockets etc.). 

The applicable three-phase nominal voltage range 

is 400 V - 690 V, 50 Hz - 60 Hz. As supplementary 

device, the measuring instrument is equipped with an 

integrated battery-powered LED pocket lamp. Before 

using the measuring instrument, carefully read this 

operating manual and always observe the safety 

instructions! 

This operating manual is addressed to

 

-  professional electricians and

 

-  electrotechnically trained people.

The TRITEST

®

 control is intended for being used in 

dry ambient conditions and must not be used for three-

phase mains with a nominal voltage higher than 690 V 

AC (also see section 9 „Technical data“).

The following symbols are used in this operating man-

ual and on the TRITEST

®

 control:

Ground (voltage to ground)

-   The device is designed and tested according to 

DIN EN 61557-7/ VDE 0413-7, DIN EN 61557-1/ 

VDE 0413-1 and left our works in technically safe 

condition. To preserve this condition and to ensure 

safe operation, the user has to observe all instruc-

tions and warnings contained in this operating 

manual.

- 

 During testing, hold the device by the insulated test 

handles A, B and C only and do not touch the 

testing electrodes (probe tips) !

-   The device may be used only in electrical circuits 

of over voltage category III with a maximum volt-

age of 400 V between the conductor and ground.

 

 With measurements within measurement category 

III, the projecting conductive part of a contact tip 

of the measuring leads must not be longer than 

4 mm.

 

 Prior to carrying out measurements within mea-

surement category III, the push-on caps provided 

with the set and marked with CAT III and CAT IV 

must be pushed onto the contact tips. The purpose 

of this measure is user protection.

-   Before opening the housing cover 4 (battery com-

partment), separate the test handles A, B and C 

from all voltage sources and measuring circuits!

-   Remove the batteries, when you do not use the 

device for a longer period of time! 

-   Do not dispose of used batteries via the house-

hold rubbish! Dispose of those batteries via special 

waste facilities!

-   Please observe: Working on live parts and sys-

tems is dangerous! Even voltages from 30 V AC 

and 60 V DC onwards might involve life-threaten-

ing dangers for people! 

-   Check the device for damages before each meas-

urement. 

-   Always protect the measuring instrument against 

moisture or dampness. Furthermore, protect it 

against contamination and damages! 

-   Protect the device against condensation water. 

Condensation water might form, if the device is 

brought from a cold into a warm environment. 

Thus, the insulating power inside the device might 

be reduced and measuring and insulating faults 

might occur. In such a case, store the device in an 

appropriate environment at a higher temperature 

for approx. 1 hour. 

-   If it can be assumed that safe operation is no long-

er possible, put the device out of operation and 

secure it against unintended operation. 

-   Safe operation is assumed to be no longer pos-

sible, if

 

-   the device exhibits visible damages (housing, 

cable, test handles),

 

-   the device no longer works,

 

-   the device has been stored under unfavour-

able conditions for a longer period of time,

 

-   the device was exposed to mechanical stress 

due to transport.

The scope of delivery of the TRITEST

®

 control consists 

of:

 

3.1   one  TRITEST

®

 control with fixed connecting 

cables, L1, L2, L3

 

3.2   one safety probe tip L1, brown (TN 709266)

 

3.3   one safety probe tip L2, black (TN 709267)

 

3.4   one safety probe tip L3, grey (TN 709268)

 

3.5   one safety alligator clip, black (jack Ø = 4 mm, 

TN 709269)

The phase-sequence indicator TRITEST

®

 control  is 

equipped with two integrated voltage divider systems 

with star connection. One of the systems indicates the 

phase LED (indication of the phase voltages L1 9, L2 

7

, L3 5). The other system (combined resistance and 

capacitor) ensures the phase-sequence indication by 

means of two LEDs 8 and 6. The capacitor  (reac-

tive impedance) and the resistances (active resistance) 

build up a phase shift and is almost in phase with a ro-

tary field (travelling wave). The respective LED (clock-

wise 8 or anti-clockwise 6 phase sequence) gets the 

higher voltage and is activated. 

The phase sequence can be tested even with the bat-

teries being removed or empty. 

Before opening the housing cover 4, separate the 

test handles A, B and C from all voltage sources and 

measuring circuits. 

The battery compartment is behind the housing cover 

4

 at the back of the device. There are apertures on 

the sides of the device to release the cover. For this 

purpose, use a 5.5 mm slotted screwdriver by means 

of which you can move the cover over the holding 

notch with a rotary movement. Thus, the cover can be 

removed.

Please ensure correct polarity when inserting the bat-

teries (see battery symbol)! 

When closing the housing, make sure that the cover 

locks into place correctly and that there is no gap on 

the side of the housing. 

In case of low battery voltage, the pocket lamp cannot 

be operated. Please replace the batteries!

Contact the connecting cables (test cables) L1, L2, L3 

with the mains to be tested. If necessary, use the probe 

tips A, B and C and the alligator clip J.

The phase voltages are indicated by means of the 

LEDs L1 9, L2 7 und L3 5. 

Depending on the connection, the LED for “clockwise 

phase sequence” 8 or for „anti-clockwise phase se-

quence”  6 is activated.  Please observe for each 

testing that all of the three phase voltages have to be 

present to obtain a correct indication! 

The LED lamp 2 can be switched on via the sliding 

switch  3 integrated into the side of the device. The 

pocket lamp function can be operated independently of 

the phase-sequence indicator system.
