Calibration:
All calibration data is held within the spYdaq transmitter, this is held together with
the date of the last calibration. The spYdaq transmitter sends the last calibration date every
time information is sent to the base-station. Signatrol Ltd recommend as 12-month calibration
interval. Please contact your agent for more information about our calibration services.
Battery:
All transmitters come with a new battery fitted. Life is dependant on transmit rate and
ambient temperature conditions. Replacements are available from your supplier.

Low Battery Warning:
The transmitter uses a coulomb counting technique for estimating
battery life as Lithium Thionyl Chloride batteries cannot be checked for capacity based on
output voltage. Using this technique the transmitter will indicate a low battery when the total
cell capacity falls below 10%. The remaining capacity value (0 to 100%) is viewable in
spYconfig using the USB connection. The battery capacity calculation is only accurate if the
battery calculations are reset every time the battery is replaced with a new battery. This can
be done through spYconfig. Never fit used batteries as the system will not generate the
correct low battery warning.

Warning
: Fire, explosion and severe burn hazard. Do not recharge, crush,
disassemble, heat, above 212 °F (100 °C), incinerate, short circuit or expose contents to
water. Keep battery out of reach of children. Dispose of used batteries promptly and safely.
