5. INTRODUCTION
The V7 data logger ALMEMO ® 710 is a brand new member in our family of unique
measuring instruments - all equipped with Ahlborn GmbH's patented ALMEMO ®
plug system. The ALMEMO ® plug offers - and has offered for the last 20 years -
decisive advantages when connecting sensors and peripherals because all param-
eters are stored in an EEPROM located on the connector itself; repeated program-
ming is thus no longer necessary. All sensors and output modules can be con-
nected to all ALMEMO ® measuring instruments in the same way.
However, the new generation of intelligent digital ALMEMO ® D7 sensors, operating
in conjunction with our V7 measuring instruments, overcomes all limitations to
which the system was previously subject. These sensors, irrespective of the de-
vice's measuring ranges and operating as an autonomous measuring system with
up to 10 channels, offer completely new measurable variables with any necessary
control functions, calculating functions, or compensation values and cover a range
of values up to 8 digits and a speed of up to 1 kHz. What is so special about this
new generation is that, thanks to individual sampling rates, high-resolution vari-
ables, both quick and slow, can now very easily be measured and recorded to-
gether. Individual sensor functions can be parametrized via a menu stored in the
plug. To facilitate identification the quantity abbreviations and units have been ex-
tended to 6 digits and channel designation to 20 characters. All sensors belonging
to the preceding V5, D6 generations can be used on V7 devices but the new D7
sensors are not compatible with V6 devices. However, they can be operated di-
rectly on the PC via the serial interface and an adapter cable. What is completely
new on V7 devices is the channel numbering system. Sensors and sockets are
counted from 0 to 9; this is followed by the channels counted as decimals also
from 0 to 9; i.e. the first sensor has channels 0.0 to 0.9, the second has 1.0 to 1.9,
etc. . However, programming and functioning are virtually identical for all units.
The following points apply to all devices in the ALMEMO ® measuring system;
these are described in detail in the ALMEMO Manual which is included in delivery
®
with each device :
- Detailed explanation of the ALMEMO system (Manual Ch. 1)
®
- Overview of the device functions and measuring ranges (Manual Ch. 2)
- Basic principles, operating instructions, and technical data for all sensors
(Manual Ch. 3)
- Options for connecting your own existing sensors (Manual Ch. 4)
- All analog and digital output modules (Manual Ch. 5.1)
- Interface modules RS232, optic fiber, USB, Ethernet (Manual Ch. 5.2)
- The whole ALMEMO ® networking system (Manual Ch. 5.3)
- All functions and their operation via the interface (Manual Ch. 6)
- Complete list of interface commands with all the printouts (Manual Ch.7)
The operating instructions you are now reading cover only those features and
controls that are specific to this device. Many sections refer to more detailed
descriptions in the Manual; (see Manual X.X.X).
