Start-up instruction
Please note the following references during the first initiation of the data logger:
• Install the software PWB-Soft including driver for the USB cable on your PC/laptop.
• Thereafter, connect the data logger to the PC/laptop using the provided PC
data cable. For that, take an
unused interface of your PC.
• Start the software.
•
Set up the serial interface in the dialog box „Settings“ of menu item „File“. You will recognize the
interface
by the indication (USB).
• Establish connection between PC and data logger via „Connection“.
•
Make all necessary settings in dialog field „Configuration“. In particular, note that a
1 minute sample rate
is adjusted and start measurement is dated ahead by one year when delivering the device in order to take
care of the accumulator.
•
After confirming by „OK“, the data logger will be configured again and the memory will be clea
red. Mea-
surement can start now.
•
Note that measurement starts only when exceeding the preset time of measurement start.

Data logger PWBlogg N6/60
The data logger has been particularly developed for logging pressure and temperature readings. Because
of its solid stainless steel case, the data logger is particularly suitable for net analysis in the field of gas and
water. The measurement range begins at 50 mbar.
Data logger
The data logger has an integrated analog digital converter with high resolution which is responsible for log-
ging and digitizing pressure and temperature readings. A microprocessor stores the readings in the integra-
ted memory. At its highest expansion stage, it can log 3,8 million readings. Data logger parameterizing as well
as reading and evaluating performance data is done on any PC, laptop or netbook with Windows operating
system by using PWB-Soft 2.1. Just a USB interface for connecting the reading cable is necessary.
Pressure measurement
Pressure can be recorded both relatively and absolutely. Relative pressure mesurement is done zero-re-
ferenced against ambient air pressure on site. A waterproofed pressure equalization element provides pres-
sure equalization inside the housing. To protect the pressure equalization element optimally from permanent
moisture penetration by submergence of the metering point, this element is connected to the data logger by
a tube. The pressure equalization element can be optimally positioned by a flexible fastener.
When taking absolute measurement, no pressure equalization is necessary as pressure is measu
red against
vacuum or a fixed pressure. To calculate relative pressure, the absolute reading can be offset against the air
pressure metered on-site and, hence, the relative pressure can be determined. But this methode is predomi-
nantly qualified for pressure reading in the bar range!
