Chapter 1. Setting Up the RF ValProbe
8 RF ValProbe® User’s Manual
1.1.6 The Logger Batteries (cont.)
Battery life is affected by a number of factors, including sample rate, temperature, Logger
position in the network, and hours of use. In addition, individual battery characteristics
and capacity vary inherently from one battery to another by up to 10%. The RF ValProbe
software tracks each Logger's battery life to within 10% of a potential low-voltage
occurrence to help prevent interrupted or incomplete studies. When determining the
battery life remaining, the software bases its calculations on the assumption that the
battery can supply a predictable amount of energy (mAh) over the temperature range.
The battery life calculation is accurate when a Logger is used exclusively for studies at or
above room temperature, or exclusively for studies below room temperature. Kaye
therefore recommends that you change the battery when switching between temperature
ranges above room temperature and those below room temperature.
A low battery warning is issued when the remaining battery life is below the warning
percentage specified in the RF ValProbe software. The low battery warning is issued until
you replace the Logger battery and reset its battery life to 100%. If you do not specify a
percentage, the low battery warning is set to 10%. Kaye recommends that you replace the
battery when there is 10% battery life remaining.
• If the battery is used up or is removed, the study setup and data, as well as the
calibration information, are maintained in non-volatile memory inside the Logger.
1.1.6a Resetting the Battery Capacity Setting
You can reset the battery capacity from the Logger itself. Once you have installed the new
batteries, press and hold the Status button on the front of the logger while you turn the
logger power switch on. Wait for the Power (green) light to blink five times, and then
release the button. The battery capacity has been reset.
