1.4. DEFINITION OF MEASUREMENT (OVERVOLTAGE) CATEGORY
Standard CEI 61010: Safety requirements for electrical equipment for measurement,
control and laboratory use, Part 1: General requirements” defines measurement category,
commonly called overvoltage category. In § 6.7.4: Measured circuits, circuits are divided
into the following measurement categories:
(OMISSIS)
• Measurement category IV is for measurements performed at the source of the low-
voltage installation.
Examples are electricity meters and measurements on primary overcurrent protection devices
and ripple control units.
• Measurement category III is for measurements performed on installations inside
buildings.
Examples are measurements on distribution boards, circuit breakers, wiring, including cables,
bus-bars, junction boxes, switches, socket-outlets in the fixed installation, and equipment for
industrial use and some other equipment, for example, stationary motors with permanent
connection to fixed installation.
• Measurement category II is for measurements performed on circuits directly
connected to the low-voltage installation.
Examples are measurements on household appliances, portable tools and similar equipment.
• Measurement category I is for measurements performed on circuits not directly
connected to MAINS.
Examples are measurements on circuits not derived from MAINS, and specially protected
(internal) MAINS-derived circuits. In the latter case, transient stresses are variable; for that
reason, the standard requires that the transient withstanding capability of the equipment is
made known to the user.

5. INSTRUMENT FUNCTIONS
5.1. PHASE DETECTION
The HT5 can be used as phase detector in the presence of voltage between 60V and
250V AC.
Measurement procedure:
Touch contact “Electrode” (see Fig. 1 - point 4) during voltage test
•
Connect test probe (see Fig. 1 – point 1) to the device under test
•
Illumination of the LED “Continuity/Voltage” indicates the presence of an AC voltage
•
between 60V and 250V. Simultaneously an acoustic sound is audible.
• A correct indication is only ensured for AC voltage circuits with a
frequency of 40-60 Hz being grounded in accordance with the
regulations
• The quality of the indication may be impaired when testing in
unfavourable locations, such as wooden ladders or in insulated floor
coverings, etc.
CAUTION

HT5
5.2. LAMP TEST
The HT5 allows you to quickly detect the presence of faults in lamps, especially for all gasfilled low pressure and high pressure vapour lamps.
Measurement procedure:
connect test probe (see Fig. 1 – point 1) to glass body or lamp socket
•
Press “Test” button (see Fig. 1 – point 5) for the duration of the test
•
Do not touch the lamp socket (this could lead to faulty test results).
CAUTION
Testing Fluorescent Tubes
If the fluorescent tubes are lit during lamp tester check but do not work when installed, the
spiral-wound filament or the ballast may be faulty. Filaments and ballasts can be tested
using the built-in continuity tester (see § 5.3)
CAUTION
Only check ballasts and capacitors when they are disconnected from live
circuits and when capacitors have been discharged. These conditions have to
be verified by measurements.
Testing low pressure sodium vapour tubes
Test tube by contacting the socket pins with test probe and observe if the inner tube is
glowing. In some cases, only part of the tube is glowing. The other part should be lit when
the test probe touches the second pin.
Testing high pressure sodium vapour tubes
Touch tube with test probe. A clear, blue line within the arched tube indicates that the tube
is in perfect condition. Any other test results indicate a defective tube.
Testing Neon Tubes
Touch tube or socket with test probe and press button Test. The tube has to be replaced if
no illumination is visible.
Testing mercury vapour and metal halogen lamps
Touch tube socket with test probe and press button Test. The arched tube is defective if
there is no constant glowing. If the tube only operates when not installed and goes on and
off or seems unstable within the lamp holder, verify if the lamp holder or the lamp are
subject to unusual or extreme heat. Unusual or extreme heat can result in repeated
opening and closing of the thermal tube switch.

5.3. CONTINUITY / DIODE TEST
HT5 allows continuity and diode tests with optical and acoustic indication.
CAUTION
Prior to any continuity test, it must be ensured that the resistance to be
measured is not live. Failure to comply with this prescription can lead to
dangerous user injuries.
Continuity test procedure:
Touch contact “Electrode” (see Fig. 1 - point 4) during continuity test
•
Connect test probe (see Fig. 1 – point 1) to one pole of the device under test
•
Touch with the other hand the other pole of device under test
•
The lighting of the LED "Continuity / Voltage" and the continuous sound of the buzzer
•
indicates continuity.
The continuity test facility enables resistance tests between 0 and approx 5 MΩ. The
resistance value can be determined by the intensity and the sound level of the acoustic
signal. A higher sound level indicates a lower resistance value (approx. 0Ω).
Simultaneously the LED Continuity is illuminated.
Diode test procedure:
Touch contact “Electrode” (see Fig. 1 - point 4) during diode test
•
Connect test probe (see Fig. 1 – point 1) to the diode cathode
•
Touch with the other hand the diode anode
•
The LED "Continuity / Voltage" must be turned on and the buzzer must sound.
•
• Connect test probe (see Fig. 1 – point 1) to the diode anode
• Touch with the other hand the diode cathode
• The LED "Continuity / Voltage" must be turned off and the buzzer must not sound.
