5.6 Datalogger Function
1. Press the REC key once to begin.
2. If the meter displays the "Change Card" message at the bottom right, the SD CARD
memory is either full or it is damaged.
3. If the meter displays "NO DISK" an SD card must be inserted.
4. If 'Check SD' appears, wait a few seconds as the meter is reading the SD card.
5. If the SD CARD is functional and it has available space datalogging will begin.
6. The display will show the datalogging process by incrementing the data counter on
the bottom right side of screen (under the REC display icon).
7. Each file can store up to 30,000 data points. When the number of data points
reaches 30,000 the system will create a new file automatically. (For example,

8. Press the REC key again to stop datalogging. The incrementing counter and the
REC display icon will switch off.
