Attention: Make sure which type of applied part is concerned! Non-observance might

cause a short-circuit, e.g. in case of an uninsulated applied part!

Note:Themeasuringaccuracyisspeciedasthesumof:

- a relative part of the measured value and

- a number of digits (i.e. counting steps of the last digit). This measuring accuracy applies to

temperatures from 18 °C to 28 °C and a relative air humidity lower than 80 %.

20.1 Technical Data, Measuring and Device Function

DIN VDE 0404-2/ 4.1.1: The tester must allow at least measurement of the following parameters:

- protective conductor resistance

- insulating resistance

- protective conductor current (direct measurement, differential current measurement or

alternative leakage current measurement method)

- contact current (direct measurement, differential current measurement or alternative leakage

current measurement method)

The application standards DIN VDE 0701-0702 and 0751-1 use different terms for the same

measurement methods depending on the properties and intended use of the parts. Thus, the follow-

ing 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

favourable measuring range.

The RS232 interface (COM port) for barcode scanner, RFID reader, PC and printer can be set as

follows:

Baud rate: 1200; 2400; 4800; 9600; 14400; 19200; 38400; 57600; 115200

Parity: none, even, odd

Data bits: 7; 8

Stop bits: none, one, two

*printed in bold type = factory setting

Max. connectable storage capacity: SD card 2 GB,

USB stick 8 GB

For data input, it is also possible to connect an external PC keyboard to the USB interface.

Factory setting, system data:

Test time: 5 seconds

Time, safety shutdown: 30 seconds

Transition resistance, connector:  1Ω
