Changing the Average Time/Average Interval
The average time can be changed as explained below.
♦ Example: “2^16” → “2^13”
1. Locate the cursor to “AVE TIMES”
(*1)
by using the rotary knob or the arrow key.
*1: “AVE TIME” is displayed if “TIMES 2^*” or “TIMES *k” is selected for “AVE
CONDITION”, and “AVE INTERVAL” will be displayed if “INTERVAL” is selected
for “AVE CONDITION”.
2. Press [ENTER].
A selection window will appear.
• The larger the average time/average interval, the higher the accuracy of
measurement results. However, measurement time will be prolonged, so an
appropriate average time/average interval must be set with the instrument’s
dynamic range and loss of optical fiber taken into account.
• The average time/average interval that can be set vary with the selected average
condition.
*: Indicates the default setting.
