The calibration can be performed by reference measurement using an external measuring de-
vice or using test gas in combination with a testing device (type 650R1015) of test gas at a
known CO
e
concentration.
For KS1D type 656R2000, a special adapter for test gas is necessary. (For the required test
gas adapter for the KS1D (Type 656R2000), see Chapter
7.1.4 Checking/Calibrating with Test
Gas ).
Recommended test gas: 3 vol.% O
2
, 200 ppm CO, 100 ppm H

, in N

CO
e
value to be set: 300 ppm
A test gas without O
2
cannot be used for the calibration. The test gas must always contain O
2
in the % area.
For the KS1D-HT (Type 656R2015), a hose connection for calibration gas through which the
test gas (40 ... 60 l/h) can be input is available.
NOTICE
Calibration / checking with a reference measurement functions only with CO
