Types of Data Recording
•
Manual Datalogging: Manually log up to 99 readings onto an SD card via push-key press.
•
Automatic Datalogging: Automatically log data onto an SD memory card where the number of
data points is 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.
With regard to orientation, the card should 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.

Manual Datalogging
In the manual mode the user presses the LOG key to manually log a reading onto the SD card.
1.
Set the sampling rate to ‘0’ seconds.
2.
Press and hold the LOG key for at least 1.5 seconds; the lower portion of the display will show
p-n (n = memory position number 1-99).

3.
Press the LOG key momentarily to log a reading into memory. The REC icon will flash each
time a data point is stored (the SCAN SD icon will appear when the meter accesses the card).

keys 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 key for at least 1.5 seconds.
Automatic Datalogging
In automatic datalogging mode the meter takes and stores a reading at a user-specified sampling
rate onto SD card. The meter defaults to a sampling rate of one second. To change the sampling
rate, refer to the Setup Mode section (the sampling rate cannot be ‘0’ for automatic datalogging):

1.
To begin an automatic Datalog session press and hold the LOG key for at least 1.5 seconds.
2.
The meter will scan for an SD card and verify that it can be used to store data. If a card is not
inserted or if the card is defective, the meter will display SCAN SD indefinitely. In this case,
switch the meter OFF and try again with a valid SD card.

5.
To terminate the datalogging session press and hold the LOG key for at least 1.5 seconds.
6.
When an SD card is used for the first time a folder is created on the card and named AMC01.
Up to 99 spreadsheet documents (each with 30,000 readings) can be stored in this folder.

7.
When datalogging begins a new spreadsheet document named AMC01001.xls is created on
the SD card in the AMC01 folder. The data recorded will be placed in the AMC01001.xls
document until 30,000 readings are reached.

8.
If the measurement session exceeds 30,000 readings, a new document will be created
(AMC01002.xls) where another 30,000 readings can be stored. This method continues for up
to 99 documents, after which another folder is created (AMC02) where another 99 spreadsheet
documents can be stored. This process continues in this same fashion with folders AMC03
through AMC10 (last allowable folder).
