Start the SmartGraph software. The program recognises the connected data logger automatically and adds the data logger to the existing data logger list. The data logger can now be configured using the software. 4.
6.2.1. The Four Operating Modes No values are displayed in any of the three lines that normally display measurements. Up to a total of 20 measurement channels, which have all been previously selected using the SmartGraph software, can be saved into the measurement memory. The message “REC” (data logging active) appears where the saved measurement values are normally displayed. Operating mode M1 6.2.2.
When the acoustic function is activated, an alarm signal alerts the user when an alarm incident occurs. The alarm for one or more than one measurement must have been previously set using the SmartGraph software. The last two digits represent the sensor number and are assigned automatically according to the log on sequence - from 01 for the first logged on sensor to 04 for the fourth logged on sensor.
.2.1 Voltage Measurement Sensors: 0 - 1V 7.2.3 Pt100 Sensors in 3-wire and 4-wire Circuit The positive pole of the voltage source is connected to terminal B and the negative pole is connected to terminal A, as shown in the diagram: In the case of the 3-wire circuit, the Pt100 sensor is connected to the measurement circuit using 3 wires. The measuring current is fed into the sensor via line D0/D1.
No sensor assignment is pre-set during initial commissioning at the factory. In the case of subsequent configurations, the last pre-set specification is assigned. By holding down the mode selection key, you can now switch to the configuration menu for the analog sensor specification. Press the mode selection key repeatedly until the desired sensor specification is displayed. Finally, confirm the desired sensor specification by holding down the mode selection key.

9.4. Using the Alarm Hysteresis If you use the alarm function with an alarm hysteresis, the alarm will be triggered and recorded every time the alarm thresholds are exceeded. If the corridor between the selected alarm thresholds is very narrow, the alarm will be triggered more often. If, for example, you have selected 24°C as your upper alarm threshold for the room temperature and 10°C for your lower alarm threshold and the room temperature fluctuates between 23.
