5. Measurement procedure mean values
By mean value measurement function, measurements can be sampled within an adjustable
time frame and mean values can be calculated. Should the several measurement values or
the mean value result be stored a storage place has to be selected as described in chapter 7.
If the function “Store” is activated, based on this storage place all measurements will be
written consecutively on the next storage places. If the function “Store” is not activated, the
mean value result can be stored on MMC with <Print> / „Memory -> M.
Once the fresh air calibration is completed, select the menu point „Mean values“. Before
starting, the parameters „Measurement time“, „Scanning“, „Printer“ and „Record“ should be
checked or modified if need be. The meaning is respectively:
- Measurement time = Time frame during which the mean values will be sampled
- Scanning = Time interval between the measurements considered for mean value
calculation
- Printer = Documentation of measurements serving to the mean value calculation
- Store = All measurements for mean value calculation will be stored
„Measurement time“ and „Scanning“ can be adjusted as follows:
- select menu point and confirm with <Enter>
- set the desired time using the numerical keys:
0.01 = 1 sec = minimal value
59.59 = 59 min : 59 sec = maximal value
- confirm with <Enter>
The settings for „Printer“ can be changed as follows:
- select menu point and confirm with <Enter>
- select desired adjustment with cursor keys
- confirm with <Enter>
The setting for „Store“ can be changed as follows:
- select menu point and confirm with <Enter>
- activate memory function with <F1> or
- deactivate it with <F4>
