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.
The ‘Change Card’ display
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,
WTA01001.XLS will be replaced by WTA01002.XLS)
8.
Press the REC key again to stop datalogging. The incrementing counter and the
REC display icon will switch off.
9.
Instructions are provided later in this User Guide regarding data exporting to a
spreadsheet using a PC.

5.7 Data Hold Function
1.
During a measurement, press the HOLD KEY once, the displayed readings will
freeze and the display will show the “HOLD” icon on the bottom right side of the
screen
2.
Press the HOLD key again to release the display and return to the normal operating
mode. The HOLD display icon will switch off

5.8 LCD Backlight Key
Press to turn the backlight ON or OFF. Note: Use of the backlight will place a higher
burden on the battery power. The backlight should be turned off when using battery power
and especially while datalogging.
5.9 Low Battery Indication (LOW BAT)
When the LOW BAT indicator appears, replace the batteries as described in the Battery
Replacement section of this manual. Use of weak batteries will compromise measurement
accuracy and meter performance.
