11.- Verification of accuracy
Materials required:
AKO-58110
calibration kit
Calibrated gas cylinder*
AKO recommends verifying the accuracy of the transmitter at least once per year. Please check what
current local regulations specify for such cases.
Always ensure that you comply with current local regulations.
Ÿ
Install the
AKO-58110
calibration kit following the instructions on page 18.
Ÿ
Open the shut-off valve of the gas cylinder and wait.
Ÿ
After a few moments, the transmitter concentration reading will begin to rise. Wait for the reading to
stabilise.
Ÿ
Compare the reading displayed with the calibrated value of the gas cylinder. If the accuracy is sufficient for
the intended application, it is not necessary to carry out a calibration. If the opposite is true, calibrate the
transmitter following the instructions set out on page 22.
Ÿ
Close the shut-off valve of the gas cylinder, disconnect the cylinder and remove the calibration kit from the
transmitter.
The transmitter may take a few moments to go back to showing the concentration values from before
the verification procedure.
*Use a cylinder with a type of gas that is suitable to the sensitivity of the transmitter to be calibrated. When
calibrating the
AKO-575400
universal gas transmitter, use a R134a gas cylinder.
