Measurements/Tests with Test Instruments

7 Measurements/Tests with Test

Instruments

7.1 General Information

When connecting a compatible test instru-

ment, additional measurements/tests are

possible which are described in this chapter.

Important information for the performance of

measurements/tests

Attention!

When turning the switch, pay atten-

tion to the exact snap-in position and

the corresponding optical signals of

the LEDs, as described in these oper-

ating instructions.

•

The test adapter must remain connected to

the mains

for protective conductor measure-

ments (

) at

mode 2 charging cables

means of the

respective test instrument.

• The test adapter can remain connected

to the mains for protective conductor

measurements conducted at test

objects whose protective conductor is

not switched, as well as for insulation

measurements (Riso) with the respective

test instrument.

7.2 Measurement of Protective Conduc-

tor Resistance (R

)

7.2.1 Mode 2 Charging Cable

As opposed to the usual default setting for

low-resistance measurements, the device

under test does not have to be disconnected

from all sources of voltage in this case. Both

rotary selector switches (S1 and S2) have to be

set to the

and the

Status C

positions, in

order to be able to activate the test object and

switch the protective conductor through. Prior

to a protective conductor resistance measure-

ment, an offset measurement must be carried

out (the offset value of the test adapter must

be taken into account during the test).

Measurement is carried out between ICCB-

OUT1-PE and OUT2-PE.

➭ Connect the

test object

as described in

chapter 5.3.

➭ Connect the test object to the ICCB-IN1

PE and ICCB-OUT1 PE sockets:

PROFITEST MF XTRA, PROFITEST MF TECH,

PROFITEST MXTRA, PROFITEST MXTRA IQ,

PROFITEST MTECH+, PROFITEST MTECH+ IQ:

2-pole measuring adapter

PROFITEST PRIME, PROFITEST PRIME AC:

probes L(1) and PE(3)

SECUTEST ST PRO: 2-pole measurement

with test probes P1 and P2 (P1-P2)

➭ Switch the test object’s ICCB on.

➭ Perform the measurement as described

in the operating instructions for the re-

spective test instrument.

7.2.2 Mode 3 Charging Cable

➭ The rotary selector switch must be set to

the R

ISO

position.

➭ Connect the

test object

as described in

chapter 5.3.

➭ Connect the test object to the ICCB-IN1

PE and ICCB-OUT1 PE sockets:

PROFITEST MF XTRA, PROFITEST MF TECH,

PROFITEST MXTRA, PROFITEST MXTRA IQ,

PROFITEST MTECH+, PROFITEST MTECH+ IQ:

2-pole measuring adapter

PROFITEST PRIME, PROFITEST PRIME AC:

probes L(1) and PE(3)

SECUTEST ST PRO: 2-pole measurement

with test probes P1 and P2 (P1-P2)

➭ Perform the measurement as described

in the operating instructions for the re-

spective test instrument.

7.3 Measuring Insulation Resistance (R

ISO

)

Attention!

Insulation resistance may only be

measured at voltage-free devices!

The upper-hand rotary selector

switch must be set to the mains dis-

connect position: R

INS

➭ Connect the test instrument to the ICCB-

IN1 socket for the mains-end of the cable

and the ICCB-OUT1 socket for the output

end of the cable of the device under test:

PROFITEST MF XTRA, PROFITEST MF TECH,

PROFITEST MXTRA, PROFITEST MXTRA IQ,

PROFITEST MTECH+, PROFITEST MTECH+ IQ:

2-pole measuring adapter

PROFITEST PRIME, PROFITEST PRIME AC:

probes L(1) and PE(3)
