Datalogging and PC Interface
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.
•
RS-232/USB:
The meter includes an RS-232/USB PC interface jack located on the lower right
side of the meter under the snap-off compartment cover. The optional software kit (PN:
407001A) includes a cable and a software program for streaming data to a PC.
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.
•
European and USA numerical formats differ. The data on the SD card can be formatted for
either format. The meter defaults to USA mode where a decimal point is used to separate units
from tenths, i.e.
20.00
. The European format uses a comma, i.e.
20,00
. To change this setting,
refer to the Setup Mode section.
