Sets mode 1 in DM0000.
Sets MAX. setting value (510 ms) in DM0001.
Sets MIN. setting value (490 ms) in DM0002.
Sets the average number of measurements (10) in
DM0003.
Measures the pulse interval when input relay 0000
turns ON.
Pauses measurement when input relay 0001 turns
ON.
Resets measurement when input relay 0002 turns
ON.
Writes the average measurement value into
DM0100 and resets 0500 after every time a
measurement is completed.
Turns On output relay 0500 when the pulse
interval is not within the range from 490 to 510
mm.
