Introduction
5. INTRODUCTION
The ALMEMO
®
2470 is a new member in our family of unique measuring
devices - all equipped with Ahlborn's patented ALMEMO
®
plug system. The in-
telligent ALMEMO
®
plug offers decisive advantages when connecting sensors
and peripherals because all parameters are stored in an EEPROM located in
the plug itself; repeat programming is thus no longer necessary.
All sensors and output modules can be connected to all ALMEMO
®
measuring
instruments in the same way. Programming and functioning are identical for all
units. The following points apply to all devices in the ALMEMO
®
measuring sys-
tem; these are described in detail in the ALMEMO
®
Manual which is included in
delivery with each device:
Detailed explanation of the ALMEMO
®
system (Manual, Chapter 1)
Overview of the device functions and measuring ranges (Manual, Chap. 2)
Basic principles, operating instructions, and technical data for all sensors
(Manual, Chapter 3)
Options for connecting your own existing sensors (Manual, Chapter 4)
All analog and digital output modules (Manual, Section 5.1)
Interface modules USB, RS232, optic fiber (Manual, Section 5.2)
The whole ALMEMO
®
networking system (Manual, Section 5.3)
All functions and their operation via the interface (Manual, Chapter 6)
Complete list of interface commands with all the printouts (Man., Chap. 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, Section xxx).
5.1 Functions
Measuring instrument ALMEMO
®
2470-1S has only one measuring input but
special variant 2470-1SRH is also available with an integrated temperature hu-
midity sensor and atmospheric pressure sensor. Types 2470-2/-2S have 2
electrically isolated measuring inputs suitable for all ALMEMO
®
-sensors.. The
measuring possibilities are virtually limitless; there are 4 channels per sensor
plug and over 70 measuring ranges. To facilitate operation the device incorpor-
ates a keypad and a large illuminated color LCD; this helps show with particu-
lar clarity various important operating states, e.g. a limit value being exceeded.
All devices incorporate a DC socket for connecting a mains adapter or special
interface cable ZA1919-DKU5 with integrated power supply. The ALMEMO
®
2470-2/-2S also incorporates output sockets A1 and A2, suitable for all AL-
MEMO
®
output modules, e.g. analog outputs, digital interfaces, and trigger and
relay cables. Several such devices can easily be networked by simply linking
them together via cable.
