INTRODUCTION Thank you for purchasing General Tools & Instruments’ DTH3007SD Thermometer-Humidity Meter with Datalogging SD Card. Please read this user’s manual carefully and thoroughly before using the instrument.
OPERATING INSTRUCTIONS WHAT’S IN THE CASE The DTH3007SD comes fully assembled in a carrying case along with a temperaturehumidity probe, a 2 GB SD memory card and this user’s manual. Optional accessories available from General Tools & Instruments include: • Type K and Type J thermocouples • A 9VDC adapter for a 110VAC power supply • A carrying case See the Optional Accessories section of this manual for more details.
1-1 Liquid-crystal display 1-2 POWER/ESC button 1-3 FUNC.
(If you press buttons too slowly in setup mode, the screen will revert to the normal display. To return to the setup sequence, press and hold the SET ▼ button again. To move ahead to the next field in the sequence or to the next parameter, press the FUNC./HOLD/NEXT button.) Once you have set the date, the display will prompt you to set the hour, minute and second of the current time. Again use the SET ▼ or LOGGER ▲ buttons to navigate to the correct values, and the REC/ENTER button to store the settings. 4.
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.
By default, the DTH3007SD is configured for a Type K thermocouple. To use a Type J thermocouple, perform Step 7 of the setup procedure. Whenever the instrument is in measurement mode, you can turn off the backlight (which is on by default) by briefly pressing (but not holding) the POWER/ESC button. To reactivate the backlight, briefly press the button again.
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. This will cause the beeper to sound and the term “LOGGER” to briefly appear at the upper right of the display. As in automatic datalogging mode, in this mode the instrument is storing measurements and their time stamps on the SD card.
SPECIFICATIONS Embedded microcontroller Custom one-chip LSI device Display type Liquid-crystal with green backlight Display size 2.05 x 1.5 in. (52 x 38mm) Parameters measured Temperature, relative humidity (R.H.), dew point, wet-bulb temperature Measurement range For temperature, 32º to 122ºF (0º to 50ºC); for R.H., 5 to 95%; for dew point, -13.5º to 120.1ºF (-25.3º to 48.9ºC); for wet-bulb temperature, -6.9º to 122ºF (-21.6º to 50ºC) Measurement accuracy ± 1.5ºF (± 0.
If the instrument “freezes” (like a computer) and buttons become unresponsive, try resetting the instrument by pushing the RESET button on its right side (callout 1-11 of Fig. 1) with the end of a paper clip. Remove the batteries when storing or not using the instrument for an extended period of time. Do not drop or disassemble the instrument or immerse it in water.
