5. Performance characteristics
5.1 General The manufacturer’s specifica-
tions in the instruction manual
shall be by no means better
than the results of the perfor-
mance tests.
No discrepancies between the in-
strument design and the instruction
manuals were observed.
yes 43
5.2 General requirements
5.2.1 Certification range
Shall meet the requirements of
Table 1 of VDI Guideline 4202
Sheet 1.
The measuring system can be as-
sessed in the range o
f the relevant
limit values.
yes 44
5.2.2 Measuring range The upper limit of measure-
ment of the measuring systems
shall be greater or equal to the
upper limit of the certification
range.
By default the measuring range is set
to 0 – 100 mg/m³ for CO. Other
measuring ranges of max. 0 –
200 ppm are possible.
The upper limit of the measuring
range is larger than the respective
upper limit of the certification range.
yes 45
5.2.3 Negative output signals May not be suppressed (life ze-
ro).
The measuring system also displays
negative measured values.
yes 46
5.2.4 Failure in the mains
voltage
In case of malfunction of the
measuring system or failure in
the mains voltage, uncontrolled
emission of operation and cali-
bration gas shall be avoided.
The instrument parameters
shall be
secured by buffering
against loss. When mains volt-
age returns, the instrument
shall automatically reach the
operation mode and start the
measurement.
When mains voltage returns the
measuring system goes back to a
failure-free operational status and au-
tomatically resumes measuring.
yes 47
5.2.5 Operating states The measuring system shall al-
low the control of important op-
erating states by telemetrically
transmitted status signals.
By means of various connectivity op-
tions and the “Serinus Downloader”
software the measuring system can
be monitored and controlled from an
external PC.
yes 48
5.2.6 Switch-over Switch-over between meas-
urement and functional check
and/or calibration shall be pos-
sible telemetrically by computer
control or manual intervention.
In general, all necessary tasks related
to functional checks may be per-
formed directly on-
site or monitored
telemetrically using the remote control
functions.
yes 49
5.2.7 Maintenance interval
Preferably 3 months but at
least 2 weeks.
As determined by the necessary
maintenance tasks the maintenance
interval 4 weeks.
