HOBO U20 Water Level Logger
4
If you would like to have your logger’s absolute accuracy verified
against a NIST standard, or to have your logger recalibrated, contact
Onset or your place of purchase for pricing and return arrangements.
Battery
The battery in the HOBO Water Level Logger is a 3.6 Volt lithium
battery. The battery life of the logger should be about five years or
more. Actual battery life is a function of the number of deployments,
logging interval, and operation/storage temperature of the logger. To
obtain a five-year battery life, a logging interval of one minute or
greater should be used and the logger should be operated and stored at
temperatures between 0° and 25°C (32° and 77°F). Frequent
deployments with logging intervals of less than one minute, and
continuous storage/operation at temperatures above 35°C will result in
significantly lower battery life. For example, continuous logging at a
one-second logging interval will result in a battery life of
approximately one month.
The logger can report and log its own battery voltage. If the battery
falls below 3.1 V, the logger will record a “bad battery” event in the
datafile. If the datafile contains “bad battery” events, or if logged
battery voltage repeatedly falls below 3.3 V, the battery is failing and
the logger should be returned to Onset for battery replacement.
To have your logger’s battery replaced, contact Onset or your place of
purchase for return arrangements. Do not attempt to replace the
battery yourself. Severe damage to the logger will result if the case is
opened without special tools, and the warranty will be voided.
WARNING:
Do not cut open, incinerate, heat above 100°C
(212°F), or recharge the lithium battery. The battery may explode
if the logger is exposed to extreme heat or conditions that could
damage or destroy the battery case. Do not dispose of the logger
or battery in fire. Do not expose the contents of the battery to
water. Dispose of the battery according to local regulations for
lithium batteries.
