3.3.4.3 READING AVERAGE TIMES
READING AVERAGE TIMES option can set the average times the MAIN PAGE displays.
The default is 2 as Figure 3-65 shows. When changing the READING AVERAGE TIMES
default, the average method can be changed.
[ D I S P L A Y S E T U P ]
B R I G H T N E S S = H I G H
D I S P L A Y S E L E C T I O N = N O N E
R E A D I N G A V E R A G E T I M E S = 2 _

Follow the steps below to change the average times and method:
1.
Use “ ”, “ ” keys to move the cursor to the column to be set.
2. Use the numeric keys
0
~
3 or “Rotary” (
) to select the desired average
times. READING AVERAGE TIME can be set to 1, 2, 4 and 8.
3. Move the cursor to AVERAGE METHOD and use the numeric keys (
0
~
1
)
or “Rotary” (
) to select the desired average method. AVERAGE METHOD has
FIXED and MOVING 2 types.
1. Assuming setting the READING AVERAGE TIME = 8, AVERAGE
METHOD:FIXED, readings sampling is that the device clears all of the
old samples (A1 ~ A8) in the buffer and saves the new samples (B1 ~
B8), then averages them in repetition as Figure 3-66 shows.

2.
Assuming setting the READING AVERAGE TIME = 8, AVERAGE
METHOD:MOVING, the readings sampling is that the device removes
the oldest sample in the buffer and saves a new sample, then
averages them in repetition as Figure 3-67 shows.
