Mean Value Measurement (Option) - Ecom -D Operating Instructions Manual

9. Mean Value Measurement (option)

The mean value measurement function allows you to sample meas-
urements in an adjustable time frame, and to calculate the average of
those results. Should the several measurement values or the average
calculation need to be saved, a save file has to be selected as de-
scribed in chapter 7. If the "Store" function is used, all measurements
will be placed in numeric order starting with the number of the first
saved file. If the "Store" function is not used, the results can be
stored on MMC with <Print> / <Memory -> M>.
Once the fresh air calibration is completed, select
<Mean values>. Before starting, <Measurement
time>, <Scanning>, <Printer> and <Record>
should be modified as needed. See their use below:
- Measurement time = the length of time the meas-
urements will occur
- Scanning = Time interval between the
measurements considered in the average value
calculation
- Printer = Documentation of
measurements of the average value calculation
- Store = All measurements for average
value calculation will be stored
<Measurement time> and <Scanning> can be adjusted as follows:
- Select value you want to change and confirm with <Enter>
- Set the desired time using the numerical keys:
0.01 = 1 sec = minimal value
59.59 = 59 min: 59 sec = maximum value
- Confirm with <Enter>
