Battery Replacement

The 5-segment battery life indicator allows the user to track the status of the battery. When
all 5-segments are dark, the battery is fully charged. Segments switch off as the battery
ages. When the battery indicator has only one segment left the batteries must be replaced
immediately.
1. Open the battery compartment on the rear of the instrument
2. Remove the old batteries and replace with three (3) heavy duty alkaline 'AA'
batteries observing polarity
3. Replace the battery compartment cover securely
4. The RH520 will require a "Programming Reset" to reset the display. Press the
RESET button located inside the battery compartment. "Reset" clears all settings.
Time, Date and the logging interval need to be entered. The measurement data
and alarm history, however, will still be retained in the non-volatile memory.
