[. . . ] You can end the data collecting by pressing ON/OFF. 6. 5 Reading the measurement results The measurement results can be read in the REC READ mode. This mode can be entered from the REC AUTO mode by pressing twice the button MODE. The following appears: Press ENTER, and a text similar to the following appears on the display: RH % T °C Numbers on the first line indicate the reading of the quantity in question (in this example, RH). The number on the left on the second line (in this example number 0. ) is the sequence number of the measurement. This number helps to 23 HMI41 AND PROBES Operating Manual M210316EN-A estimate the time of the measurement stored during automatic data collecting provided that the starting time and the measurement interval are known. Numbers on the right on the second line indicate the temperature reading measured simultaneously with the reading on the first line; if you wish to see the decimals, press ENTER. The reading appears on the display with one decimal: RH T % °C In a couple of seconds the indicator returns to the previous display. Press MODE to change the quantity on the first line: Td T °C °C If you press ENTER (with any quantity on the first line), an arrow appears on the higher right hand corner of the display: RH T % °C Press HOLD while the arrow is displayed to scroll the measurement results (note that the sequence number changes): RH T % °C HOLD: RH T % °C etc. If the button HOLD is pressed continuously, numbers change in a faster rate. 24 M210316EN-A HMI41 AND PROBES Operating Manual 6. 5. 1 MIN and MAX in data collecting REC READ mode When the data collecting REC READ mode has been activated, the HOLD button brings four different modes on the display: MIN HI, MAX HI, MIN LO and MAX LO. These modes indicate the maximum and minimum readings measured for the quantities on the display. HI and LO tell you whether the reading observed is the one on the first line (HI) or the one on the second line (LO). MIN and MAX indicate whether the reading on the display is the minimum or the maximum value. In other words, if the text is MIN HI it means that you are now observing the minimum reading of the quantity on the first line. By pressing HOLD repeatedly you can change from one display mode to another, and by pressing MODE you can change the quantity on the first line. In all these modes, the decimals of the second line reading are shown by pressing the button ENTER. Examples: RH % RH % ENTER T min °C Hi T °C Hi returns automatically min (minimum reading of the 1st line quantity) (decimals of the 2nd line) HOLD RH % RH % ENTER T max °C Hi T °C max Hi returns automatically (maximum reading of the 1st line quantity) (decimals of the 2nd line) HOLD RH % RH % ENTER T min °C Lo T °C Lo returns automatically min (minimum reading of the 2nd line quantity) (decimals of the 2nd line) HOLD RH % RH % ENTER T max °C Lo T °C max Lo returns automatically (maximum reading of the 2nd line reading) (decimals of the 2nd line) 25 HMI41 AND PROBES Operating Manual M210316EN-A 7. TRANSFERRING THE STORED READINGS TO A PC The readings that have been stored in the HMI41 memory manually or automatically in the data collecting mode, can be transferred to a computer and then printed if desired. In order to do this, connect a serial connection cable (order code 19446ZZ) to the appropriate connectors on your PC and in the HMI41: connect the serial cable to the EXT connector Figure 7. 1 7. 1 Connecting the cable Giving the communication parameters Give the communication parameters when using this terminal session for the first time; save them for future use.
