PowerTap Cervo 2.4 Pro - Manual (Page 31)

5 - Cadence Test
NOTE: The C icon is displayed
The top line display shows crank cadence sensor RPM. The middle line flashes “88”
with each pulse from cadence sensor. The bottom display shows cadence RPM value
from the hub.
6- Torque Information
NOTE: The T icon is displayed.
This displays information about the internal workings of the torque readings. The bot-
tom display is the offset torque value directly sent by the hub torque with no correc-
tion applied. The hub sends a value of approximately 512 as the zero point. The middle
line display is the correction offset value currently stored in the computer. This is the
value that is changed when you do a manual zeroing of the torque. The top display is
the corrected actual torque (the bottom value minus the
middle value).
7 - Standard Test File
This mode writes a small test file to the memory. Press [SELECT] and the bottom lines
says "run" and then "yes" when the file is written. This file can then be downloaded.
8 - Communication Loop Back Test
When looking at the front side of the computer, use a coin or paper clip to short out
the two pins on the left side. Press [SELECT]. The bottom line will say "run" and then
"yes" if it passes the test correctly. If the pins are not shorted together or there was a
problem, the display will say "no". This test can be repeated by pressing [SELECT].
9 - Fast Memory Test
This tests the memory in the computer. Press [SELECT] and "run" is displayed on the
bottom line. When the test is completed and it passes, it says "yes". If the test should
fail, the bottom line will say "no".
