4.10.2 Routine Site Visit Checklist
A routine site visit should include the following activities:
1. Check sensor readings to assess sensor condition. Readings that vary widely with expected norms may
indicate a sensor malfunction. Press [Home][1], then [Up] or [Down] to scroll through the sensors.
2. Check the logger’s clock (time and date are displayed at the bottom of the home menu screen). Correct the
clock, if needed (remember the clock is set to Standard time). Loggers connected to an iPack that is configured
for Time Service will be automatically updated via SNTP or GPS; there should be no need to adjust the clock
manually.
3. Press [Home][2][1][2] to view internal and iPack battery voltages and 12 V sensor current level. Press the
[Right] arrow key to view the D-cell battery voltage and additional internal diagnostic voltage readings. Press the
[Right] arrow key again to view analog reference voltages.
4. If D-cell battery status shows low battery voltage, replace D-cell batteries one at a time. Use only alkaline D-
cells, IEC type LR20. If the iPack battery is low (i.e. below 11 V) but it is under 2 years old, contact NRG Systems
for troubleshooting assistance. Please be prepared to provide all diagnostic voltage and current readings. If the
iPack battery is low and the battery is more than 2 years old, it may need to be replaced.
5. If an SD card is installed, pull the SD and label it with the date and site number. The SD card should not be
pulled while the SD card is being accessed by the iPack (the SD card icon will be animated).
6. Insert and format a new SD card [Home][2][1][3][1].
7. Check SD card status [Home][2][1][1].
8. If any condensation is noticed inside the enclosure, replace the desiccant pack with a fresh one from a sealed
package.
4.10.3 Cleaning
If it should become necessary to clean the SymphoniePRO data logger, use a cloth slightly dampened with water
and wipe clean. Do not use solvents. Never submerge the unit.
