6.4.2 DTG-RTD100-W Battery Life – Wireless Model
For the DTG-RTD100-W digital RTD meter, the battery life of the device is
controlled by three variables – the battery capacity, the analog output rate, and
the wireless transmission rate. The battery capacity is 17000 mA hours using 2 of
the 8.5Ah capacity batteries. Below is a table showing battery life estimates for
various sample intervals and wireless transmission rates.
