There are two pump styles available. The correct style will have been set in the factory. If a cold start is performed, the
wrong style may be wrongly selected. To find out which one is in your Analyzer, undo the 2 screws on the sides and
bring the door forward. If the CM-15 pump has been installed it will be visible on the lower PCB.
Options:
External MV-05 (Black pump mounted on the chassis, rear of the cabinet)
Internal CM-15 (Yellow pump mounted on the 1630-2 PCB) *
57. DAMPING FACTOR
This factor is only used if ‘Continuous’ is selected in set-up 26, Sample Mode.
Each time a new reading is read from the oxygen sensor, the new reading is averaged with the last readings taken,
before the new average is either displayed on the LCD, or sent to the 4 to 20 mA output. The number of readings that
are averaged together is adjustable with this function. A value of five for example, means that the new reading from
the sensor and the previous four readings are averaged together before being displayed. A value of zero entered here
will mean that every new reading from the sensor will be sent to the display unaltered.
The smoothing of the oxygen signal is an exponential function. If a factor of 5 is used, a step change of input signal
will take about 5 seconds to reach 63% of the change on the output/display.
Range
0 to 20. Default setting is 5.
