PD6830 Pulse Input Rate/Totalizer Instruction

Gate Function (
Gate
)
The gate function is used for displaying slow pulse rates. Using the programmable
gate, the meter is able to display pulse rates as slow as 1 pulse every 999 seconds
(0.001 Hz). The gate function can also be used to obtain a steady display reading
with a fluctuating input signal.
There are two settings for the
Gate
, low gate (
Lo Gate
) and high gate (
HI Gate
).
Low Gate (
Lo Gate
)
For most applications, low gate setting should be left at 1 second. Increase low gate
setting to obtain a steadier rate display. The rate display will update in accordance
with the low gate setting, for example if low gate is set at 10, the display will update
every 10 seconds; changes in rate between updates will not be reflected until next
display update.
High Gate (
HI Gate
)
Set the high gate value to correspond to the highest expected pulse period (lowest
pulse rate). For instance if the meter must display a rate when there is 1 pulse
coming into the meter every 10 seconds, set the high gate to 11 seconds. When the
signal is removed from the meter, the display will show the last reading for 11
seconds; then it will read zero.
