SETUP 1. Choose the power source. Before using the DLAF930SD, make sure it is powered by fresh batteries or an optional 9VDC AC adapter plugged into the bottom jack on its right side (callout 1-12). To remove the battery compartment cover (callout 1-13), remove the two screws holding it in place (callout 1-14). Then install six “AA” batteries in the correct orientation, using the polarity marks on the inside of the compartment as a guide. Replace the cover by replacing the two screws. 2. Install an SD card.

4. Choose a decimal point or comma to represent the decimal division between integers and fractions (for example, American-style 20.88 vs. European-style 20,88). Once you have set the date and time, the display will show the word “bASIC” above the phrase “dEC”. Press the SET ▼ button to make “bASIC” (American style) or “Euro” appear in the upper display, as desired. Press the REC/ENTER button to store the selection as the default. 5. Enable or disable auto power off.

If you choose “yES”, after you press the REC/ENTER button the instrument will prompt you to confirm that decision by displaying the term “Ent” below “yES” and sounding three beeps. To confirm that you want to begin the erasure/formatting procedure, press the REC/ENTER button. “Ent” will then flash several times and the instrument will sound another three beeps to confirm that the SD card has been erased and formatted.

4. To measure air temperature and humidity simultaneously, seat the multifunction probe plug in its socket on the top of the meter. Then press the FUNC./HOLD/NEXT button until the display shows the term “rH”. Holding the probe by its handle, expose its head to a representative volume of air whose temperature and humidity you wish to measure. The upper part of the display will show the measured relative humidity value (as “%RH”) while the lower part will show the temperature (as “ºF” or “ºC”). 5.

Whenever the instrument is in measurement mode, you also can check the current date and time by briefly pressing the SET ▼ button (which has the words “Time check” stenciled below it). Doing so causes both values to appear briefly at the lower left of the display. HOLDING AND STORING MEASUREMENTS 8. To hold a measured value, press the FUNC./HOLD/NEXT button during the measurement. Doing so will cause the word “HOLD” to appear at the top of the display. Pressing the FUNC.

14. To log data manually, set the sampling time to zero using the procedure detailed earlier. Then press the REC/ENTER button once. The display will show the term “REC” on the top line, a value in the middle, and below it the letter “P” on the left and a number from 1 to 99 on the same line to the right. The number indicates the position on the SD card that will be used to store manually logged data. Now press the LOGGER ▲ button.
