Operation

Note:

The unit does not have a power switch. Power is always on when batteries are installed or the AC adaptor is plugged in.

Battery Warning, Installation and Replacement

1. 2. 3. 4. When the low battery icon appears in the display the batteries are weak and should be replaced. However, in-spec. measurements may still be made for several hours after the low battery indicator appears before the instrument reads inaccurately. To replace or install batteries, remove the Philips head screw that secures the rear battery cover and lift off the cover. Replace the six (6) ‘AAA’ batteries (use alkaline heavy duty type), observing polarity. Replace and secure the cover.

Datalogging

1. Open the left side door and insert an SD card

Notes:

 The SD card should be at least 1GB in capacity.  Do not use memory cards formatted by other meters or cameras. Use the SD card formatting procedure under the advanced features section of this manual to correctly format the card.  The internal clock must be set to the correct time. See the advanced features section of this manual to set the clock.  The default data structure uses a decimal point “.” as the numeric decimal indicator. See the advanced features section to change this to a comma “,”  If the SD memory card is not installed, “EMPTY” will appear in the display.  Displayed error messages: CH- CArd The memory card is full or there is a problem with the card LobAt The battery is low and datalogging is disabled 2. 3. No CArd The SD card is not inserted Pre ss the LOGGER button for >2 seconds to begin logging. “DATALOGGER” will appear in the display and the meter will beep each time the data is recorded (if the beeper is enabled). To stop datalogging, press the LOGGER button for >2 seconds. “DATALOGGER” will change to “DATA” and the meter will count down through the recorded data.

Note:

To protect data, do not remove the memory card without properly ending the record function.

Time/Date/Sample Rate Check

Press and Hold the TIME button for >2 seconds and the display will cycle through the date, time and sample rate information. 4 SD700-en-GB_v2.7 8/18

SD Card Data Structure

1. 2. 3. When the SD card is first inserted into the datalogger the folder HBA01 is created. The first datalogging session will then create a file HBA 01001.xls. All data will be saved to this file until the number of rows reaches 30,000. After 30,000 rows, a new file (HBA010

.xls) is created. This is repeated every 30,000 rows until HBA010

.XLS. At this point a new folder, HBA

is created and the process is repeated; HBA

is the final folder.

Transferring Data to a PC

1. 2. Remove the memory card from the datalogger and plug it into the SD card slot on the PC. Launch Excel® and open the data file on the memory card from within the spreadsheet program. The file will appear similar to the one shown below. 5 SD700-en-GB_v2.7 8/18

Advanced Settings

The SET function is used to accomplish the following:  Format the SD memory card  Set the date and time      Set the sampling time Set the beeper sound ON/OFF Set the SD card decimal/comma character Select the units of measure for temperature and barometric pressure Set the RS232 data output ON/OFF

Note:

The datalogger function must be switched OFF before attempting to enter the Advanced Settings mode. Press and Hold the SET button for >2 seconds. The first function (Sd F) will appear in the display. Press the SET button to step through all of the functions. Use the ▲ and ▼ buttons to adjust the se lected function. Use the “LOG” button to step through fields within a function. In the SET mode, if no button is pressed within 5 seconds the logger will revert to the standard mode. 1. 2.
