Gate times for frequency measurement within the range 250 ¼ 5000 ms
Operating mode
Settings are made for both counter channels for operating mode frequency meas-
urement or pulse counting and gate time.
Frequency measurement
The appropriate measuring process is automatically selected. The time interval of
registered pulses is measured in the range 0.2 to 100 Hz (or 12 ¼ 6000 rpm)
range. In the >100 to 30 kHz range, the number of pulses are measured per gate
time.
A gate time setting of 1000 ms is recommended. The table shows the values for 1
pulse/rotation, a gate time of 1000 ms and a sampling frequency of 1000 Hz:
