MAINTENANCE INSTRUCTIONS
CHANGING BATTERIES
When the red front-panel LED labeled Low Battery lights up, it’s time to replace the
instrument’s four “AA” batteries. To do so, follow the procedure in the Setup Instructions
section of this manual.
CHANGING THE FILTER
The RLD400 ships with a pack of five small disc filters that install upstream of the
sensor. Replace the filter whenever it becomes visibly dirty, or every few months,
depending on use.
To change the filter, unscrew the black plastic tip of the probe from the black plastic
sensor enclosure (see figure on p. 6.) Remove the old filter, install the new one, and then
screw the plastic tip back into the enclosure.
