[. . . ] The duration time can be selected in steps according to the following: · · · · 15 min; 30 min 1 - 6 h: each pressing = 1 h 12 h 1 - 7 d: each pressing = 1 d If the duration selected is too long for the current battery charge, the text 'BAT' appears. 6. 4 Setting the measurement interval min (previously set interval) In this mode, you can set the time between two measurements stored, e. g. When entering this mode, previously set interval appears on the display. If the previously set measurement interval is too short for the current memory capacity of the indicator, the shortest calculated measurement interval appears instead. This is also indicated with the text 'MIN'. 22 M210316EN-A HMI41 AND PROBES Operating Manual Select the interval with buttons and . The measurement interval can be selected in steps according to the following: · · · · 1 - 5 min: each pressing = 1 minute 10 min; 15 min; 30 min 1 - 6 h: each pressing = 1 hour 12 h The text 'LO' on the display indicates that there is not enough memory for the chosen interval; select a longer interval. When you press ENTER, a text similar to the following appears: RH T set % °C This is the measurement mode with the data collecting feature activated. It can be distinguished from the normal measurement mode by the text 'SET' on the lower lefthand corner of the display. The readings on the display are updated once a minute, and the display is dim except during this updating in order to minimize the consumption. If the indicator is turned off, the measurements stored so far remain in the memory and they can be read by turning the indicator on in the REC READ mode (see section 6. 5). 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.
