*1	Based on 2^15 average cycles.
*2	Based on average fiber loss of 0.3 dB/km using single mode fiber.
*3	Based on the measurement of strain-free, UV-coated fiber.
*4	Based on the measurement with strain-free, UV-coated fiber and in constant temperature environment.
*5	Maximum standard deviation of measurement value in 5 consecutive measurements for 100 consecutive points.
*6	Within the allowable range adjusted by the optical power excluding the case of nonlinear phenomena.
*7	The settings of 50 m distance range, 2^8-14 count settings, 41 scanning steps excluding the time for Pulse Adjustment.
1-6 are all based on a frequency scan step of 5 MHz and with Pulse Adjustment and Auto Frequency Adjustment on.
