5. Introduction Conversion between °C (Centigrade) and °F (Fahrenheit) is performed auto- matically. Measured value designation To help identify sensors an alphanumeric designation is also provided (V5 10 characters, D7 up to 20 characters). This designation appears in each mea- sured value display, in the printout, or on the computer screenm. -

Functions of the ALMEMO® 204 Analog output and scaling Each measuring point can be scaled by means of analog start and analog end in such a way that the measuring range thus defined covers the full range of the bar chart or of an analog output (2 V, 10 V, or 20 mA). At the analog output the device can output the measured value from any measuring point or a pro- grammed value. - Page 14 5. Introduction Output cycle The output cycle can be programmed to any value from 1 second to 24 hours. This function permits cyclic output of measured values to the interface or to the memory and provides cyclic calculation of the average value. Cycle factor The cycle factor can be used to restrict data output from certain channels;...

Page 19: Standard Sensor (V5)
Standard sensor (V5) 8.1 Standard sensor (V5) ALMEMO ® V5 sensors are housed in a light-gray case. The source of their intel- ligence is an 2-KB EEPROM integrated in the sensor plug, in which all channel settings are stored; the device is thus programmed completely as soon as such a sensor is connected. -

Connecting sensors / transducers 8.4 Measuring inputs und additional channels Measuring instrument ALMEMO ® 204 incorporates four input sockets M0 and M3; to these, under the new channel numbering scheme, measuring channels M0.0 to M3.0 are initially assigned. (1) Whereas standard sensors can if nec- essary provide up to four channels (M0.0 to M0.3, M1.0 to M1.3, etc.), D7 sen- sors can provide up to 10 (M0.0 to M0.9, M1.0 to M1.9, etc.). -
