Note:
The measuring accuracy is calculated as the sum of a relative part
of the measured value.
This measuring accuracy applies to temperatures from 18 °C to
28 °C and a relative air humidity lower than 80 %.
27.1 Technical data, measuring and device function
DIN EN 61557-16:2015-12:
The tester must allow the measurement of at least the following
parameters:
 protective conductor resistance
 insulating resistance
 protective conductor current
(direct current, differential current or alternative leakage current
method)
 contact current
(direct current, differential current or alternative leakage current
method)
The application standards VDE 0701-0702, VDE 0751-1 and
VDE 0544-4 use different terms for the same measuring methods
depending on the properties and intended use of the parts. Thus,
the following terms are used for leakage currents:
device leakage current, earth leakage current, protective
conductor current, contact current, patient leakage current etc.
The measuring data logging works with three measuring ranges
(1:1, 10:1, 100:1). Switch-over of the measuring range occurs
automatically, so that measurement is always carried out in the
most favorable measuring range.
Connections:
 separate 4 mm test sockets and IEC connector
 4 x USB interface (type A), 1 x USB interface (Mini B)
 1 x SD card slot
 1 x RJ45
Max. storage capacity of the storage media:
 SDHC card max. 32.0 GB
 USB stick max. 32.0 GB (FAT32 file system)
Factory settings, system data:
