5.5. Period Measurement
1. Input the measured signal to Channel A/BNC socket (3-2, Fig. 1) via BNC
cable (optional, PB-21 or BB-22)
2. Select the "Period Switch" Switch (3-14, Fig. 1). Select the "10 MHz range
Sensitivity Switch" (3-19, Fig. 1) to the "HIGH" (high sensitivity) or
"NORMAL" (normal sensitivity) position.
*
To select the "HIGH" sensitivity normally.
3. Slide the Gate Time Switch (3-18, Fig. 1) to the "FAST" or "SLOW" position
to determine the convenient sampling time & display resolution.
*
To select the "FAST" gate time normally.
Consideration:
* The input frequency range for period function is from 10 Hz to 10 MHz.
* The display will show 5 digits then following the unit:
" - s" represent milli – seconds "us" represent micro - seconds
* The principal of period display is calculated from the measured
(Hz), the formulas are following:
period (ms) =
or period (us)=
* The period range accuracy are based on the digit No. + 1 (max. 5 digits) of
measured frequency. For example if measured frequency is 615 Hz (3
digits), then the period values accuracy will be on the leading four digits
(1.626 mS).
* If no signal input (0 Hz), the display will show over range (- - - oL - - -).
