User Manual Heavy Duty Differential Pressure Manometer Model SDL710 Additional User Manual Translations available at www.extech.
Introduction Congratulations on your purchase of the Extech SDL710 Pressure Manometer. This device measures gauge and differential pressure in the range of ±2.9 psi. Supported measurement units are mbar, psi, Kg/cm2, mm Hg, inch Hg, meters of H2O, inches of H2O, atmosphere, hPA, and kPA. Logged data readings are stored on an SD card for transfer to a PC. This meter is shipped fully tested and calibrated and, with proper use, will provide years of reliable service. Please visit our website (www.extech.
Getting Started Power ON‐OFF Power the meter by pressing and holding the power button Press and hold the power button for at least 1.5 seconds to power OFF the meter. This meter is powered by six (6) 1.5VDC ‘AA’ batteries or by optional AC adaptor. If the meter will not switch ON please check that fresh batteries are installed in the rear battery compartment or, in the case of the AC adaptor, check that the adaptor is connected correctly to the meter and to an AC source. for at least 1.5 seconds.
Setup Mode Basic settings at a glance To view the current configuration of the meter with regard to time, date, and datalogging sampling rate press the SET button momentarily. The meter will now display the configuration in quick succession. If the information is missed on the first try, simply press the SET button again until all of the information is noted. Accessing the Setup mode 1. 2. 3. 4. 5. Press and hold the SET button for at least 1.5 seconds to access the Setup menu.
Enabling/Disabling the Auto Power OFF Feature 1. 2. 3. 4. Access the PoFF parameter. Use the arrow buttons to select ON or OFF. With the Auto Power OFF feature enabled, the meter will automatically switch OFF after 10 minutes of inactivity. Press ENTER to confirm setting. Press and hold the SET button for at least 1.5 seconds to exit to the normal operation mode (or simply wait 7 seconds for the meter to automatically switch to the normal operating mode). Set the Beeper Sound ON or OFF 1. 2. 3. 4.
Max‐Min Reading Record For a given measurement session, this meter can record the highest (MAX) and the lowest (MIN) readings for later recall. 1. 2. 3. 4. 5. Press the MAX‐MIN button momentarily to access this mode of operation (REC icon appears) The meter is now recording the MAX and MIN readings. Press the MAX‐MIN button again to view the current MAX readings (MAX icon appears).
Manual Datalogging In the manual mode the user presses the LOG button to manually log a reading onto the SD card. 1. Set the sampling rate to ‘0’ seconds as described in the Setup Mode section. 2. Press and hold the LOG button for at least 1.5 seconds and the DATALOGGER icon will appear on the LCD; the lower portion of the display will show p‐n (n = memory position number 1‐99).
SD Data Card to PC Data Transfer 1. 2. 3. 4. Complete a datalogging session as detailed above in the previous sections. Hint: For the first few tests, simply record a small amount of test data. This is to ensure that the datalogging process is well understood before committing to critical, large scale datalogging. With the meter switched OFF, remove the SD Card. Plug the SD Card directly into a PC SD card reader.
Hose Couplings This meter is supplied with a pair of hose couplings. They fit 4.0 mm (0.157”) tubing. See diagram on how to connect these couplings to the hose and the meter. 9 SDL710-en-GB_V1.
Battery Replacement and Disposal When the low battery icon appears on the LCD, the batteries must be replaced. Several hours of accurate readings are still possible in this condition; however, batteries should be replaced as soon as possible: Remove the two (2) Phillips screws from the rear of the meter (directly above the top of the tilt stand). Remove and safely place the battery compartment and screws where they will not be damaged or lost. Replace the six (6) 1.
