Application
The
PROFI
TEST
M
ASTER
measuring and test instrument is used for
rapid and efficient testing of protective measures in
accordance with DIN VDE 0100, part 600:2008 (Erection of
low-voltage installations; tests – initial tests), ÖVE-EN 1 (Austria),
SEV 3755 (Switzerland) and other country-specific regulations.
The device is equipped with a microprocessor and complies with
IEC 61557/EN 61557/VDE 0413 regulations:
Part 1: General requirements
Part 2: Insulation resistance testers
Part 3: Loop resistance testers
Part 4: Instruments for the measurement of resistance at
earthing conductors, protective conductors and bonding
conductors
Part 5: Earthing resistance testers
Part 6: Instruments for the testing of proper functioning of
residual current devices (RCDs) and the effectiveness of
protective measures in TT and TN systems
Part 7: Phase sequence testers
Part 10:Combined instruments for the testing, measuring or
monitoring of protective measures
It is especially suited for:
• Systems set-up
• Initial start-up
• Periodic testing
• Troubleshooting for electrical systems
All measurement values required for approval reports (e.g. ZVEH)
can be acquired with the instrument.
All acquired data can be archived, and measurement and test
reports can be printed out at a PC. This is of special significance
where product liability is concerned.
The applications range of the
PROFI
TEST
M
ASTER
covers all
alternating and three-phase current systems with nominal
voltages of 230 V / 400 V (300 V / 500 V), and nominal
frequencies of 16
2
/
3
/ 50 / 60 / 200 / 400 Hz.
The following measurements and tests can be performed with the
PROFI
TEST
M
ASTER
:
• Voltage / frequency / phase sequence
• Loop impedance / line impedance
• RCD protective circuits
• Earthing resistance / earth electrode potential
• Standing surface insulation resistance / insulation resistance
• Earth leakage resistance
• Low-value resistance (potential equalization)
• Leakage current with current transformer clamp
• Meter start-up
• Cable length
See section 20.2 regarding testing of electrical machines per DIN EN 60204.
For periodic tests in accordance with BGV A3, see section 20.3.

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).
