Q: Why can’t I calibrate my sensor?
A: Not all sensors can be calibrated using the same calibration routine. The available
calibration modes are determined by the detected sensor.
Q: Why does my calculator use up batteries so quickly?
A: The calculator is using battery power any time it is turned on. An application such as
EasyData puts an added load on the batteries when it communicates with a connected data-
collection device. USB devices like the EasyTemp and EasyLink draw all of their power from
the calculator’s batteries. In addition, there are some sensors that put an even greater strain
on the batteries.
Q: Why doesn’t EasyData work with my CBR 2?
A: When used with a TI-83 Plus or TI-84 Plus calculator, the CBR and CBR 2 must be
powered by a strong set of batteries. If you are experiencing problems, replace the batteries in
the CBR or CBR 2.
Q: Why doesn’t EasyData automatically launch when I connect my EasyTemp or EasyLink?
A: Connecting a USB data-collection device will only start EasyData if the calculator in on the
home screen.
Q: Why isn’t my salinity sensor working with EasyData and an EasyLink?
A: Some older Vernier Salinity Sensors may not be properly identified by EasyData. To avoid
this problem, start EasyData and wait until the main screen appears before connecting the
sensor.
Q: Why does my calculator turn off while I am running EasyData?
A: In order to prolong the life of the calculator batteries, EasyData will automatically power
down (APD) the calculator in times of inactivity. If no keys are pressed and data collection is
not currently active, the calculator with APD after approximately 5 minutes. The calculator will
never be allowed to APD during Two Point Calibrations, Events with Entry and Selected
Events data collection, Zeroing or when waiting for a Trigger or digital event.
