*1 About the auto zero time
*2 Input lter
When the input pulse becomes 0Hz during the measurement, and the auto zero time is elapsed, the display is reset to zero.
Set the input lter with the larger value than the input signal frequency.
Note) When the duty of the input signal (proportion of the ON time in one cycle) is low, the signal may be attenuated and the pulse may not be received
normally even if you set the lter with a larger value than the input frequency. When this occurs, set the lter with an even larger value.
Example) When the 15kHz signal is input, set the 30kHz lter.
*In mode 2 and mode 3, the zero reset display is “-.-.:-.-.:-.-.”.
*When a smaller value than the input pulse cycle is set as the auto zero
time, the auto zero function is activated for every pulse, which disables
the normal measurement.
