Powering-up the PrimeProbe2 Sensor
The PrimeProbe2 Remote can receive power from either lithium (non-
rechargeable) batteries or mains power.
Battery
To avoid rapid depletion of the battery(s), the sampling rate is preset to 5
seconds (refer to the E. saving setting description in the Measure sub-
menu section beginning on page 26). The user can adjust this rate, but this
may sacrifice battery life. Refer to the battery life specification (Chapter
5, Battery Life, on page 44) to determine the expected battery life for
different sampling regimens. ADS supplies 4 lithium batteries: a single
pack and a 3-pack of batteries.
Mains
When using mains power, the PrimeProbe2 operates in continuous
sampling mode. The user may leave one lithium battery (single-pack)
installed under mains power to serve as a backup battery in the event of a
mains failure. If the mains power becomes unavailable, the unit will
automatically switch over to the backup battery as the power source.
Connecting the Battery Packs
In battery mode, the user can connect either 1 lithium battery or 4 lithium
batteries. One battery can serve as either the sole power source or the
backup power supply to a mains-powered unit. Using 4 batteries can
provide up to a 10-year battery life. Refer to the Battery Life table in
Chapter 5, Battery Life, on page 44.
To activate the batteries as the main power source, first activate the
applicable dip switch. In the Off mode, the PrimeProbe2 will not use the
battery pack connected to that terminal. In the ON mode, the PrimeProbe2
will use the battery pack as the main source of power.
With the batteries connected (and no mains power), turning the dip switch
to ON will power-up the converter (similar to an On/Off switch).
