Measured Data Acquisition; Online Measurement With Pc; Offline Measurement - Ahlborn ALMEMO 5690-1M Operating Instructions Manual

10. MEASURED DATA ACQUISITION

Measured data acquisition can be performed in basically two ways :
1. Perform measurement online and transfer data to the PC immediately (no
device-internal memory required).
2. Perform measurement offline, i.e. the data is first saved to the device
memory (option S) or to an external memory connector with multimedia
card and then transferred to the PC later.
10.1

Online measurement with PC

For conveniently recording measured data on the PC the measured data ac-
quisition software Win-Control is ideally suited. It is unique in that it can scan
one stand-alone or several internetworked measuring modules at its own
measuring cycle, then save the measured data on the PC, and output it online
in a clearly understandable form as a line diagram, table, or list; thus for pro-
cess control purposes just program the measuring cycle in Win-Control. There
are numerous other possibilities using formula channels, control and regulation
functions, alarm reports via SMS and e-mail, etc. but it would be going too far
to describe all these here in detail.
10.2

Offline measurement

To perform offline measuring operations, i.e. data logging in the device itself,
you need either option S with a 500-KB EEPROM on the master measuring
circuit board or an external memory connector with a memory card (ZA 1904-
SD) connected at A2 (2f). It is an indispensable prerequisite that the following
parameters be configured :
1. Date, time-of-day
2. Cycle with saving to memory activated
3. Sleep mode, possibly
The easiest way to do this is by means of the AMR-Control software, in menu
<Program device>. If necessary you can clear the memory in the menu <Data
memory>.
To start and stop a measuring operation on site there are numerous methods
available; (see Manual 6.6).
1. Press the START / STOP key (2) on the device.
2. Program the start date and time-of-day and then either the end date and
time-of-day or the measuring duration (see Manual 6.6.2).
3. Reaction to overshooting / undershooting a limit value (see Manual 6.6.3).
4. Triggering in response to electrical signals (see Manual 6.6.4).
The status of a measuring operation and of data recording can easily be
traced by watching the LEDs (see 9.2).
To read out the measured data (see Manual 6.9.3) select AMR-Control menu
item <Devices - Data memory>. Here you can transfer to a file on the PC ei-
ther the complete memory or parts of it selected according to date and time-of-
day or by number; the device memory can then be cleared.
