battery, thus maintaining data integrity. You can also operate the Sensor from two parallel
batteries for longer sessions.
If operating from a 110-120 volt AC power source, connect the power
supply to one of the PWR connectors on the Sensor using the supplied power
cable. Plug the power supply into the 110-120 volt AC source. If operating
in the field from a battery, connect the battery to one of the PWR connectors
on the Sensor using the supplied power cable; the white wire on the power
cable connects to the + terminal of the battery, the black wire connects to the
- terminal of the battery. There are two power connectors in parallel to allow
for redundancy when using the Sensor. Should you have two power sources
and two power cables, connect both to allow extended operational time.
The Sensor is internally protected in case the battery connections are unintentionally reversed.
Powering On the Sensor
1. After Sensor has been properly cabled, press the On/Off button to apply
