2 Applications

The PROFITEST MASTER and SECULIFE IP measuring and test instru-

ments allow for quick and efficient testing of protective measures

in accordance with DIN VDE 0100, part 600:2008

(Erection of low-

voltage installations; tests – initial tests), as well as

ÖVE-EN 1 (Aus-

tria), NIV/NIN SEV 1000 (Switzerland) and other country-specific

regulations.

The test instrument is equipped with a microprocessor and com-

plies with IEC 61557/EN 61557/VDE 0413 regulations:

Part 1: General requirements

Part 2: Insulation resistance

Part 3: Loop resistance

Part 4:

Resistance of earth connection and equipotential bonding

Part 5: Earth resistance

Part 6: Effectiveness of residual current devices (RCD) in TT, TN

and IT systems

Part 7: Phase sequence

Part 10:Electrical safety in low-voltage systems up to 1000 V AC

and 1500 V DC – Equipment for testing, measuring or

monitoring of protective measures

Part 11:Effectiveness of type A and type B residual current moni-

tors (RCMs) in TT, TN and IT systems

The test instrument is especially well suited for:

•System setup

• Initial start-up

• Periodic testing

• Troubleshooting in electrical systems

All of the values required for approval reports (e.g. for ZVEH) can

be measured with this instrument.

All acquired data can be archived, in addition to the measurement

and test reports which can be printed out at a PC. This is of spe-

cial significance where product liability is concerned.

The applications range of the test instruments covers all alternat-

ing and three-phase current systems with nominal voltages of

230 V / 400 V (300 V / 500 V) and nominal frequencies of 16

50 / 60 / 200 / 400 Hz.

The following can be measured and tested with the instruments:

• Voltage / frequency / phase sequence

• Loop impedance / line impedance

• Residual current devices (RCDs)

• Insulation monitoring devices (IMDs) (only

MXTRA

SECULIFE IP

)

• Residual current monitoring devices (RCMs) (only MXTRA)

• Earthing resistance / earth electrode potential

• Standing surface insulation resistance / insulation resistance

• Earth leakage resistance

• Low-value resistance (potential equalization)

• Leakage currents with current transformer clamp

• Residual voltage (only MXTRA)

• Voltage drop

• Leakage current with leakage current adapter

• Meter start-up (not

SECULIFE IP

)

• Cable length

Refer to section 21.3 regarding testing of electrical machines in

accordance with DIN EN 60204.

Refer to section 21.4 regarding periodic testing in accordance

with DGUV provision 3 (previously BGV A3).

2.1 Using Cable Sets and Test Probes

• 2 or 3-pole measuring adapter included

• 2-pole measuring adapter with 10 m cable as optional acces-

sory: PRO-RLO II (Z501P)

• KS24 cable set as optional accessory (GTZ3201000R0001)

Measurements per DIN EN 61010-031 may only be performed in

environments in accordance with measuring categories III and IV

with the safety cap attached to the test probe at the end of the

measurement cable.

In order to establish contact inside 4 mm jacks, the safety caps

have to be removed by prying open the snap fastener with a

pointed object (e.g. the other test probe).
