CheckPoint O

sensor temperature sensitivity

Due to the sensor design the readout will be

affected when moving the device from cold to

warm temperatures or vice versa.

Normally for compensation to work properly the

device must be stabilized at the current ambient

temperature for some time (up to 1-2 hours).

However if you cannot wait for this time, use

short stabilizing time, for example 10-15 min.,

and perform an offset (20.9%) calibration of the

sensor right before each measurement series

until device has stabilized.

This will bring the calibration back in line with

current response.

Calibration

CheckPoint O

only has to be calibrated with

atmospheric air. If CheckPoint does not show

approx. 20.9 % O

(between 21.3 % and 20.5 %)

when measuring atmospheric air, it must be

calibrated with atmospheric air. Make sure that

only atmospheric air is sucked during calibration.

External power supply/charger (14)

CheckPoint can be connected to an external

power supply/charger. When the power supply is

connected/disconnected, the display shows

"P.On" and "P.OF.", respectively. If CheckPoint is

fitted with ordinary batteries, they will be

disconnected. If CheckPoint is fitted with

rechargeable batteries, they will be recharged

automatically.

WARNING! Only connect the original

power supply.
