External Sensors

• For External Sensor Specifications, see the sensor's user manual.

Battery Life

• The batteries will last one year in typical conditions (logging intervals of ? 1 minute with weekly offloads and average temperatures greater than 10°C or 50°F). Frequent offloads and/or extreme temperatures will reduce battery life.

• At temperatures below freezing (0°C or 32°F), batteries will typically require replacement every six months. In these conditions the battery level bar graph should be checked regularly.
