Then you may: 

a. Press the 

F3

 

key to clear statistics variables and exit. 

b. Press the 

F4

 

key to continue without clearing the statistics variables. 

c. Press 

SEND

 key to transmit the Average Measurement to the output port.  

 
If 

Pr25

 is set to 

0

, the Standard Averaging method is used and the LCD displays 

AG 

for 1 second followed by the Standard Average: (Measurement Sum ÷ 

Count) 
 
If 

Pr25

 is set to any 

non-zero

 value, the LCD displays 

AAG 

for 1 second 

followed by Trimmed Average ((Measurement Sum - Max - Min) ÷ (Count - 2)) 
 
 

Notes

 on the Statistics Function: 

Standard averaging will be influenced by the Minimum and Maximum 
measurement values. If these values vary greatly from the measurement 
population, the average will not reflect a “centered” representation of the 
measurement population. 
 
Trimmed averaging, in this implementation, subtracts the Min and Max values 
prior to 

the averaging calculation. This yields a more “centered” representation 

of the measurement population that will be closer to the median value of the 
measurement population.  
 
Lack of memory resources limits this Function to Averaging.  Only a running 
summation is kept in memory, not the value of each measurement sample. 
Because of this, we cannot calculate the statistical values of median or 
standard deviation. On the other hand, this implementation allows for a large 
number of measurement samples to be accumulated. Measurement count can 
be up to 65,536 samples. Measurement summation can be 9.223 x 10
