13.7 Hysteresis

The hysteresis for an alarm triggered in the event of a limit value being exceed-
ed can be set generally for all sensors from 0 to 99 digits (default 10 digits) in
the Hysteresis function (see 12.5 and Manual 6.2.7).
To modify hysteresis (0 ... 99) see 8.5:

13.8 Operating parameters

Certain operating parameters can be configured by the user as software op-
tions in the

14. OUTPUT MODULES

The ALMEMO 2590 measuring instrument has
®
two output sockets A1 and A2; these can output
measured values in either analog or digital form or
as an alarm signal. It is also possible to initiate
various functions by means of trigger pulses. To
cover all possibilities while also keeping the hard-
ware to a minimum all necessary interfaces have
been integrated on the ALMEMO
output modules. These output modules, just like
the sensors themselves, are recognized automatically and listed in the menu
OUTPUT MODULES . The numerous connection possibilities are described in detail
in the Manual, Ch 5.

14.1 Data cables

All ALMEMO data cables and their connection to devices are described in detail
®
in the Manual, Section 5.2. Other modules for networking the devices are de-
scribed in detail in the Manual, Section 5.3. The interface modules are connected
to socket A1 (2); this is with the exception of network cable ZA 1999-NK which is
used for networking a further device; this must be connected to socket A2.
In the menu under the socket concerned the following information is displayed :
Variant 0 : Serial standard interface always active
The baud rate is also saved in the cable connector
function; (see Manual 6.10.13.2).
