Calibration with test-gas ampoules
Use the calibration flask (Part No. 68 03 407) – Observe the information in

the sensor data sheet.
Follow the instructions printed on the calibration flask and enclosed with the

test-gas ampoules.
For units without a pump:
1 Fit the adapter and calibration bottle to the Polytron 7000.
Break the test-gas ampoule inside the calibration flask.

Wait until the measured value has settled (see the operating instructions for

the sensor for the necessary waiting period). Then carry out calibration.
For units with a pump:
— The pump adapter is already installed on the Polytron 7000.
Insert the adapter (Part No. 68 04 620) in the calibration flask – connect the

hoses.
Break the test-gas ampoule inside the calibration flask and wait until the

measured value has settled (see the operating instructions for the sensor
for the necessary waiting period). Then carry out calibration.
