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;... -
Page 10: Sensor Programming
5. Introduction 5.1.1 Sensor programming The measuring channels are programmed, completely and automatically, via the ALMEMO plugs. However, this programming can be supplemented or ® modified via the keypad or via the interface as and when required for measur- ing purposes. Measuring ranges Appropriate measuring ranges are available for all sensors with a non-linear characteristic, e.g. -
Page 11: Measuring Operation
Functions Limit values and alarm Per measuring channel two limit values can be set (1 maximum and 1 minim- um). In the event of one of these limit values being exceeded the beeper sounds and the display backlighting changes from white to red. This alarm status can be cancelled at the touch of a button. -
Page 12: Process Control
5. Introduction pressure sensors, and O2 sensors; on this device this is performed automatic- ally by means of an integrated atmospheric pressure sensor. Measured value smoothing Measured values of an unstable, fluctuating nature can be smoothed by taking a sliding average over a number of values programmable from 2 to 99. Maximum and minimum values For each measuring operation the maximum value and minimum value are ac- quired and saved to memory. - Page 13 Functions Measuring rate All measuring points are scanned at the measuring rate (2.5 or 10 mops). The output of all measured values via the interface can also be performed at the measuring rate; this will accelerate recording. Measured value memory (2470-1S/2S only) On data logger 2470-1S or 2470-2S all measured values can be saved to its internal EEPROM either manually or automatically per cycle.

7. Power supply bar indicates the approximate charge status. While the 3 green sections flash left to right, the rechargeable batteries are being charged. As soon as all 3 sections remain green, the rechargeable batteries are fully charged; however, the mains adapter can be left connected to the device. If standard non-re- chargeable batteries are being used, the battery symbol will, as soon as the mains adapter is connected, flash briefly in red. -
Page 17: Data Buffering
Data buffering 7.7 Data buffering The sensor's programming is stored in the EEPROM on the sensor plug; the device's calibration and programmed parameters are stored in the EEPROM on the device itself; both are fail-safe. Date and time-of-day settings are re- tained intact if the device is just switched off but will be lost as and when the batteries are replaced. -

Potential separation taic relays and a potential difference of maximum 50 VDC or 60 VAC is per - missible between them. However, sensors combined within one plug and sensors with their own power supply are electrically interconnected and must therefore be operated in isolation. The voltage at the measuring inputs them- selves (between B, C, D and A or - ) must not exceed 5 volts. - Page 20 9.

Measuring operations 10. MEASURING OPERATIONS With the ALMEMO ® 2470 all available measuring channels are by default scanned continuously; this permits continuous differential measurements and ensures continuous temperature compensation for dynamic pressure probes or chemical probes. (see Manual, 6.5.1.3) Up to 12 measuring channels can be displayed. -

10. Measuring operations Setting to zero automatically deletes the maximum and minimum val- ues for this channel. The MAX, MIN, and MEM functions are thus also available for relative measuring. 10.6 Sensor adjustment Many types of sensor need to be adjusted either once or at regular intervals to compensate for various instabilities. -

Sensor adjustment 2. Gain adjustment For the purposes of gain adjustment the gain calibration resource must first be set up (as per the Table). Gain adjustment is started, similarly, by pressing key PROG and performed in exactly the same way as zero-point adjustment. -
Page 30: Functions
10. Measuring operations ference M1 - M0 appears automatically below the measuring point M4. The sensors are electrically isolated by means of photovoltaic relays. If the differen- tial channel is not required, it can be deleted via the interface. If. on the other hand, further differential channels are needed, these can be created also via the interface using the appropriate reference channels. -
