If Apollo has the correct sensor number chosen, follow the same steps to ensure the configuration is correct
by comparing with the calibration certificate that came with the sensor. If it is the case that the wrong values
have been entered (likely to be a decimal place out somewhere), follow the instructons in Section 2.4 to edit
the wrong configuration, and enter the correct one as stated in the calibration certificate.
C: Wrong Connection Mode chosen
In rare cases, the connecton mode of Apollo may have been changed. This is the programmed method
for Apollo to receive and interpret signals from attached sensors. For Skye sensors, the connection mode
should be “Mode 3” which is differential input mode.
To check the connection mode of Apollo, go to Menu Rd Sensr Setup Choose the sensor # you are

] to bottom of the list to “Connection Mode”. If you are using a skye sensor, and the
connection mode is NOT “3”, follow the instructions in Section 2.4 to enter the “Edit Sensor Setup” menu, and
press [Esc] for each parameter until you reach the “Connection Mode” option. Use the tu buttons to choose
the correct connection mode.
If you have a sensor from a different manufacturer to Skye you may well need to change the connection
mode from 3 to the appropriate connection mode. First of all however, make sure that the sensor you are
using is compatible with Apollo – look at the requirements set out in Appendix 2, and we can always help
you out here at Skye – give us a call or drop us an
If you know it should be compatible, and are confident you know which connection mode is appropriate –
the following is an indication of what each connection mode is. Again if in any doubt, contact Skye.
Mode 3 = Differential Floating
Mode 4 = Differential Grounded
Mode 5 = Differential (2.5V referenced)
My batteries do not last as long as 24 hours
There are several questions to consider with this, as many things need to be taken into consideration.
Our estimation of 24 hours battery life is based on laboratory tests and is merely an approximation.
Questions include – Are you using high quality Alkaline batteries (e.g. duracell)? Are you using rechargeable
batteries? These require frequent recharging, and are prone to last less that “one-use” batteries. What are
the environmental conditions of using Apollo? Battery life may be less in lower (<20
o
C) temperatures. What
type of sensor are you using? Amplified sensors require some power to operate (to amplify the output) and
as such will reduce the battery life of Apollo.
The messages on the screen are too fast/too slow!
This can also be configured. Simply go to Menu Msg Duration
→
and choose a more appropriate
length for these. We imagine more experienced users would prefer these to be shown for a shorter period of
time whilst new users would want to take more time to read the messages. The default value for this is 2
seconds, however you can choose a value between 0.5 seconds up to 7 seconds.
