6.1 5.3.8 Sensitivity coefficient of supply voltage
The sensitivity coefficient of supply voltage shall not exceed the requirements of Ta-
ble 2 of VDI 4202, Sheet 1 (September 2010). A value c
t
at 70 % to 80 % of the up-
per limit of the certification range shall be used as reference point.
The sensitivity coefficient of supply voltage shall not exceed 0.3 (µmol/mol)/V (i.e.
(0.35 mg/m³)/V).
6.2 Equipment
Not applicable here.
6.3 Testing
Performance and evaluation of the steps taken to determine the sensitivity coefficient of sup-
ply voltage are in line with the requirements stipulated in DIN EN 14626 (2012). The reader is
therefore referred to section 7.1 8.4.10 Sensitivity coefficient to electrical voltage.
6.4 Evaluation
Please refer to section 7.1 8.4.10 Sensitivity coefficient to electrical voltage.
6.5 Assessment
Please refer to section 7.1 8.4.10 Sensitivity coefficient to electrical voltage.
Does this comply with the performance criterion? yes
6.6 Detailed presentation of test results
Not applicable in this instance.
