(2) Fit the calibration button anti-tamper screw and washer.
6.6 SETTING GAS BOTTLE CONCENTRATIONS
If, at the start of span calibration, it is noted that the test gas
concentrations certified on the gas cylinders being used differ
from the expected concentrations shown on the Put <> GAS
screens, then the expected values must be reset as follows.
(1) With the Put <> GAS screens displayed, press the
internal calibration button to obtain the first of the
GAS bot screens.
(2) Adjust the expected concentration value, appearing in
the lower right section of the screen, by means of the I/O
(increase) and O (decrease) buttons until the screen
reads the same as the value certified on the gas cylinder.
(3) Press the calibration button to step on to the next screen
in the sequence and repeat the setting operation. As an
example, the following illustrations show the sequence
for carbon monoxide, hydrogen sulphide and explosive
gases.
