PPM LOG
– Contains records of the last 200 measurements. Each
record shows the measurement’s date, time, and ppm level.
Measurements are logged at an interval determined by the
LOG INT
function. After all 200 locations are filled the newest entries overwrite
the oldest entries.

Keypad
Up
and
Down
buttons to change the record number
