    Functions of the ALMEMO 5690-2M 5.1.1 Sensor programming The measuring channels are programmed, completely and automatically, by ® the ALMEMO connectors. However, the user can easily supplement or mod- ify this programming via the keypad or via the interface. Measuring ranges Appropriate measuring ranges are available for all sensors with a non-linear characteristic, e.g.

    Functions of the ALMEMO 5690-2M correction are used as the background temperature and the emissivity factor. Maximum and minimum values Each measuring operation acquires and stores the maximum and minimum values with date and time-of-day. These values can then be displayed, printed out, or deleted from memory.

    Operation with rechargeable battery (only with module ES5690-AP) hours the batteries are fully recharged and the LED goes out again. After a cer- tain period the batteries are recharged again; the charge circuitry then switches over to trickle charge. The mains adapter can thus be left permanently con- nected to the measuring instrument in buffer mode without risk of overcharging the batteries.

    8. Connecting the transducers 8. CONNECTING THE TRANSDUCERS ® Virtually any ALMEMO sensor can be connected to the input sockets on ® ALMEMO modules types (6) and (7). To connect your own existing sensors ® you simply need the appropriate ALMEMO connector.

  • Page 21: Extending The Measuring Points

    Measuring inputs and additional channels can be exchanged without losing the function channels. However, if the whole application operates with just one sensor, then programming on the sensor it- self makes more sense. On the measuring circuit board this gives the following channel assignment: Sensor channels Device internal channels 4.

    12. Programming using the programming menus 12.5.3 Baud rate, Data format The baud rate for all interface modules is programmed on leaving the factory to 9600 baud. In order to avoid unnecessary problems when networking several devices together the baud rate should not be altered; rather the computer or printer should be set to match.

    Trouble-shooting 13. TROUBLE-SHOOTING Data acquisition system ALMEMO 5690-2M can be configured and pro- grammed in many versatile ways. It is suitable for connecting a wide variety of very different sensors, additional measuring instruments, alarm signaling de- vices, and peripheral equipment. Given these numerous possibilities the de- vice may in certain circumstances not behave quite as expected.
