To change this setting: Access the dEC parameter. Use the arrow buttons to select USA or EUro. 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).

Page 6: Data Logging
Max‐Min Reading Record For a given measurement session, this meter can record the highest (MAX) and the lowest (MIN) readings for later recall. 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). The readings on the display are now the highest readings encountered since the REC icon was switched on (when the MAX‐MIN button was first pressed). Press the MAX‐MIN button again to view the current MIN readings (MIN icon appears). The readings on the display are now the lowest readings encountered since the REC icon was switched on (when the MAX‐MIN button was first pressed). To exit the MAX‐MIN mode, press and hold the MAX‐MIN button for at least 1.5 seconds. The meter will beep, the REC‐MAX‐MIN icons will switch off, the MAX‐MIN memory will clear, and the meter will return to the normal operating mode. Fittings Connection Connect tubing to the P1 (+), P2 (‐), or both input port(s). If both inputs are used (differential mode), the meter displays a positive pressure reading if the P1 (+) pressure is greater than P2 (‐) and a negative reading if P2 (‐) is greater than P1 (+). Datalogging Types of Data Recording Manual Datalogging: Manually log up to 99 readings onto an SD card via push‐button press. Automatic Datalogging: Automatically log data onto an SD memory card where the number of data points is virtually limited only by the card size. Readings are logged at a rate specified by the user. SD Card Information Insert an SD card (from 1G size up to 16G) into the SD card slot at the bottom of the meter. The card must be inserted with the front of the card (label side) facing toward the rear of the meter. If the SD card is being used for the first time it is recommended that the card be formatted and the logger’s clock set to allow for accurate date/time stamping during datalogging sessions. Refer to the Setup Mode section for SD card formatting and time/date setting instructions. SDL730-en-GB_V1.0 12/16... -

3. Momentarily press the LOG button to store a reading. The DATALOGGER icon will flash and the beeper will sound (if set to ON) each time a data point is stored. 4. Use the ▲ and ▼ buttons to select one of the 99 data memory positions in which to record. 5. To exit the manual datalogging mode, press and hold the LOG button for at least 1.5 seconds. The DATALOGGER icon will switch off. Automatic Datalogging In automatic datalogging mode the meter takes and stores a reading at a user‐specified sampling rate onto an SD memory card. The meter defaults to a sampling rate of two seconds. To change the sampling rate, refer to the Setup Mode section (the sampling rate cannot be ‘0’ for automatic datalogging): Select the sampling rate in the Setup Mode to a value other than zero. Press and hold the LOG button for at least 1.5 seconds. The meter will flash the DATALOGGER icon at the selected sampling rate indicating that readings are now being automatically recorded to the SD card. If a card is not inserted or if the card is defective, the meter will display EMPTY and exit the DATALOGGER mode. In this case, switch the meter OFF and try again with a valid SD card. Pause the datalogger by pressing the LOG button momentarily. The DATALOGGER icon will stop flashing and the sample rate will display for a short time. To resume logging simply press the LOG button again momentarily. To terminate the datalogging session press and hold the LOG button for at least 1.5 seconds. When an SD card is used for the first time a folder is created on the card and named PMA01. Up to 99 spreadsheet documents (each with 30,000 readings) can be stored in this folder. When datalogging begins a new spreadsheet document named PMA01001.xls is created on the SD card in the PMA01 folder. The data recorded will be placed in the PMA01001.xls document until 30,000 readings are reached. If the measurement session exceeds 30,000 readings, a new document will be created (PMA01002.xls) where another 30,000 readings can be stored. This method continues for up to 99 documents, after which another folder is created (PMA02) where another 99 spreadsheet documents can be stored. This process continues in this same fashion with folders PMA03 through PMA10 (last allowable folder). SDL730-en-GB_V1.0 12/16... -
Page 8: Ac Power Adaptor
SD Data Card to PC Data Transfer 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. If the PC does not have an SD card slot, use an SD card adaptor (available at most outlets where computer accessories are sold). Power the PC and run a spreadsheet software program. Open the saved documents in the spreadsheet software program (see example spreadsheet data screen below). Spreadsheet data example AC Power Adaptor This meter is normally powered by six (6) 1.5V ‘AA’ batteries. An optional 9V power adaptor is available. When the adaptor is used, the meter is permanently powered and the power button will be disabled. SDL730-en-GB_V1.0 12/16... -
Page 9: Hose Couplings
Hose Couplings This meter is supplied with a pair of hose couplings. They fit 4.0mm (0.157”) tubing. See diagram on how to connect these couplings to the hose and the meter. SDL730-en-GB_V1.0 12/16... -
Page 10: Battery Replacement And Disposal
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) 1.5V ‘AA’ batteries observing correct polarity. Replace the battery compartment cover with the two (2) Phillips screws. Never dispose of used batteries or rechargeable batteries in household waste. As consumers, users are legally required to take used batteries to appropriate collection sites, the retail store where the batteries were purchased, or wherever batteries are sold. Disposal: Do not dispose of this instrument in household waste. The user is obligated to take end‐ of‐life devices to a designated collection point for the disposal of electrical and electronic equipment. Other Battery Safety Reminders o Never dispose of batteries in a fire. Batteries may explode or leak. o Never mix battery types. Always install new batteries of the same type.
