4. Sa ety instructions
4. SAFETY I STRUCTIO S
DA GER Danger to life and limb, risk of damage to equipment
Read the instructions carefully before starting to operate
the device.
Please ensure that you comply with all general safety ad-
vice and the special safety instructions included in other
chapters.
Such risks may occur in the ollowing circumstances :
•Failure to heed the operating instructions and all the
sa ety notes these contain
•Any orm o unauthorized tampering or alteration in-
side the device
•Use o the device in environments or conditions or
which it is not suited
•Use o the device with an unsuitable power supply
and / or in conjunction with unsuitable peripheral
equipment
•Use o the device or any purpose other than that or
which it is intended
•Damage caused by electrostatic discharge or light-
ning.
DA GER Risk of fatal injury caused by dangerously high voltage
Such risks may occur in the ollowing circumstances :
•Use o the device with an unsuitable power supply and
/ or in conjunction with unsuitable peripheral equip-
ment
•Damage caused by electrostatic discharge or lightning
•Do not run sensor lines in the vicinity o high-voltage
power cables.
•Be ore you touch any sensor lines, ensure that all
static electricity has been discharged.
DA GER Warning - explosive atmospheres or substances
In the vicinity o various uels or chemicals there is a risk o ex-
plosion.
Do not use the device in the close vicinity o blasting work or ill-
ing stations!

Special notes on use
4.1 Special notes on use
•I the device is brought into the work-room rom a cold environment
there is a risk that condensation might orm on the electronics. In
measuring operations involving thermocouples pronounced changes in
temperature may cause substantial measuring errors. You are ad-
vised there ore to wait until the device has adjusted to the ambient
temperature be ore starting to use it.
•Be ore using the mains adapter make sure that the mains voltage is
suitable.
•Be sure to observe the maximum load capacity o the sensor power
supply.
•Sensors with their own integrated power supply are not electrically iso-
lated rom one another
4.2 Handling batteries / rechargeable batteries correctly
When inserting batteries / rechargeable batteries ensure that
these are correctly polarized.
I the device will probably not be needed or a relatively long pe-
riod o time or i the batteries are empty, remove the batteries;
this will prevent battery acid leaking onto the device and damag-
ing it.
Rechargeable batteries should be recharged as and when nec-
essary.
You should never attempt to recharge an ordinary (non-
rechargeable) battery; it may explode !
Batteries / rechargeable batteries must never be short-circuited
or thrown onto the ire.
Batteries / rechargeable batteries are special waste and must
not be discarded together with normal domestic waste.

5. Introduction
5. I TRODUCTIO
The data logger ALMEMO® 2890-9 is a new instrument rom the unique prod-
uct range o measuring devices that are all equipped with the ALMEMO® con-
nector system, which has been patented by Ahlborn GmbH. The intelligent
ALMEMO® connector provides important advantages with regard to the con-
nection o sensors and peripherals as all parameters are stored in an EEP-
ROM within the connector. As a result, the programming that usually has to be
per ormed or the connection is not required. All sensors and output modules
can be connected to all ALMEMO® measuring devices in the same way. The
operation and programming is identical with all units. There ore, all o the
ALMEMO® measuring system items listed below are described, in detail, in a
separate ALMEMO® manual that is supplied with every device:
Detailed description o the ALMEMO® system (manual section 1)
Overview o the device unctions and measuring ranges (manual section 2)
All sensors with basic principles, operation, technical data (man. section 3)
The options or connecting existing sensors (manual section 4)
All analog and digital output modules (manual section 5.1)
The inter ace module RS232, iber optics, Centronics (manual section 5.2)
The entire ALMEMO® networking system (manual section 5.3)
All unctions and their control via the inter ace (manual section 6)
A complete inter ace command list with all print outputs (manual section 7)
These operating instructions only cover eatures and controls that are speci ic
or a certain device. As a result, many sections will o ten provide a note re er-
ring to the more detailed description within the manual (man. sect. x.x.x).
5.1 Function Range of the ALMEMO 2890-8
The ALMEMO® 2890-9 data logger has 9 electrically isolated measuring inputs
- suitable or all ALMEMO® sensors. The measuring possibilities are virtually
unlimited; there are 36 channels in the sensor connectors and 4 device-internal
unction channels - with over 70 measuring ranges. For operation purposes the
device incorporates an LCD graphics display, a thumb-wheel, and a so t-key
keypad with cursor block. User menus can be con igured to adapt the display
or any application. The data logger unction is carried out by a real time clock
and a 512kB EEPROM memory or approximately 100000 measured values.
Two output sockets allow or connecting any ALMEMO® output modules, or
example, the digital inter ace, memory card, analogue output, trigger input or
alarm contacts. Several devices can be networked by simply connecting them
with network cables.
