4. Safety instructions 4.1 Special notes on use ● If the device is brought into the work-room from a cold environment there is a risk that condensation might form on the electronics. In measuring opera- tions involving thermocouples pronounced changes in temperature may cause substantial measuring errors. -

5. Introduction points can be programmed as function channels and can be processed like nor- mal measuring points. There are also function channels available for special measuring tasks, e.g. to determine thermal coefficient Q/ΔT and the wet-bulb globe temperature. Units The units display (V6 two characters, D7 up to six characters) can be adapted for each measuring channel in such a way that both the display and via interace always indicate the correct units, e.g. -
Page 12: Process Control
5. Introduction sors with function channels. All activated V6 measuring channels are continu- ously scanned at a rate of 10 MOPS (measuring operations per second). When there are numerous measuring points to consider, the overall response time can be shortened by increasing the measuring rate up to 100 MOPS. A D7 sensor has up to 10 channels and a sampling rate corresponding to its own individual measuring speed. - Page 13 5. Introduction fastest acting sensors, slower acting ones being omitted until new updated val- ues appear. A measuring operation can be started and stopped by means of a key, the inter- face, an external trigger signal, the real-time clock, or by a specified limit value infringement.

Page 18: Connecting Sensors / Transducers
CONNECTING SENSORS / TRANSDUCERS Virtually any ALMEMO sensor can be connected to any of the input sockets ® M0 to M8 on the ALMEMO measuring instrument (1); (this includes all standard ® V5 and V6 sensors and newer D6 and D7 digital sensors). The ALMEMO Man- ®... -
Page 19: D7 Sensors
8. Connecting sensors / transducers 8.3 D7 sensors ALMEMO D7 sensors are housed in a dark-red case; they too are completely ® autonomous measuring modules for digital and for analog sensors - but offer substantially enhanced properties. The conversion rate can be set from 1 milli- second up to several minutes with a resolution up to 8 digits. -
Page 20: Potential Separation
8. Connecting sensors / transducers 8.5 Potential separation When organizing a properly functioning measuring setup it is very important to ensure that no equalizing current can flow between sensors, power supply, and peripherals. All measuring points must therefore either be insulated (e.g. by air spacing) or lie at the same potential - and any unequal potentials that do exist must be electrically isolated. -
Page 21: Operation And Configuration
OPERATION AND CONFIGURATION Measured data acquisition module ALMEMO 809 has only a few operating con- ® trols; it is operated mainly via a PC. 9.1 Combination key The first function of the one and only key ON/OFF - START/STOP (2) has al- ready been described in Section 6.5. -
Page 22: Configuration, New V7 Functions
9. Operation and configuration 9.4 Configuration, new V7 functions For the purposes of programming and configuration the supplied ALMEMO ® Control software is ideally suited. This can be used to modify the sensor pro- gramming and to configure the process control. The various possibilities are ex- plained in detail in the Manual, Section 6.8. - Page 23 9. Operation and configuration to 8 digits plus arithmetic sign. They can also handle text, time-of-day, and coordinates. Output to an interface or to memory is now only supported therefore in the form of an ASCII string and in table format. There is thus no longer a choice between various output formats.

Page 24: Measured Data Acquisition
10. MEASURED DATA ACQUISITION Measured data acquisition can be performed in basically two ways. 1. Perform measuring operation online; data is transferred to the PC immedi- ately (no device-internal memory is required). 2. Perform measuring operation offline; data is first saved to the device’s inter- nal memory or to an external memory connector with a micro SD card and then transferred to the PC later. -
Page 25: Sleep Mode
10. Measured data acquisition Measured value memory>. (see Man. 6.9.3) Here you can transfer to a file on the PC either the complete memory or parts of it selected according to date or by number; the device memory can then be cleared. 10.2.1 Sleep mode For long-term monitoring involving long measuring cycles where power is sup-... -

SPECIAL MEASURED QUANTITIES, LINEARIZA- TION, MULTI-POINT CALIBRATION Thanks to the new ALMEMO V6 connectors with extra memory for additional ® data (bigger EEPROM, code E4) the following tasks can now be performed with a certain elegance. 1. Provision of special measuring quantities with internal characteristic 2. - Page 28 12. Trouble-shooting Error Measured values are incorrect. Remedy Check all the channel programming very carefully, especially the base value and zero-point (sensor programming and special functions). Error Measured values fluctuate unexpectedly or the system hangs in mid- operation. Remedy Check the cabling for any inadmissible electrical connections. For sensors with their own integrated power supply check element flag 5.
