Inspect Shipment for Damage
Carefully inspect the entire shipment for damage in the presence of the shipper’s agent, removing
packaging material if necessary. Note any damage to packaging and/or goods on Packing List and
have it signed by the shipper’s agent prior to accepting the shipment. Submit damage claim to
MRU immediately.
NOTE: Damage claims not received by MRU within 3 days of receipt of shipment will not be ac-
cepted.
Important notice!
This high quality electronic analyser utilizes batteries that discharge even when the
analyser is not in use. Therefore it is very important to charge the batteries every 4 – 6
weeks, even if the analyser is not in use. When it is fully charged, the analyser
should be switched on and allowed to zero itself before being switched off again. (see
chap. 11.8)
Failing to properly charge the batteries will void your warranty!
Save the original box and the packing material for use if the analyser must be shipped in the future.
The products described in this manual are subject to continuous development and improvement

ages customer feedback and welcomes any comments or suggestions relating to the product or

MRU shall not be liable for any loss or damage whatsoever arising from content errors or misinter-
pretation of information’s from this manual or any mis-use resulting from the use of this manual.
Electrochemical sensors are by their operating principle not only sensitive to the gas they are in-
tended for, but for other gases as well.
This cross sensitivity is compensated by MRU for the typical application of flue gas analysis.
However, unusual high concentration levels of single gas components might lead to
•a reduced measurement accuracy of other gas components
•and to a temporary change of the sensitivity of sensors, which may require several hours
recovery time.

Especially concentration levels as high as several % for single gas components may affect the
measurement of other gas components at ppm level. Those applications need to be discussed with
MRU in detail.

2 INTRODUCTION
2.1 The OPTIMA 7 - NDIR
The OPTIMA 7 - NDIR flue gas analyser is used for: total measurement of up to 5 car exhaust gas
components:
CO / CO2/HC infrared (ndir) measurement
O2and NOx electrochemical measurement
Simultaneous measurement of:
HC as (n-Hex) 0 - 20.000ppm
CO20 - 20,00 %
CO 0 - 16,000 %
O20 - 21,00 %
NO 0 - 5.000 ppm
