Examples of frequency measurements:
1) You would like to measure a frequency up
to 1000 Hz. Frequencies are recorded by the
HMG per minute. Enter "60" as the Factor to
display the frequency in Hz, enter "1000" for
the Upper measurem. range to scale the Y-
axis from 0 to 1000 in the graphical display.
2) You would like to measure the speed of a
machine from 0 to 2900 rpm, the speed sen-
sor supplies 2 pulses per revolution. Enter
"2" as the Factor and "3000" as the Upper
measurem. range. The display is then in
revolutions per minute; for the graphical dis-
play, the Y-axis is scaled from 0 to 3000.
3) A flow rate measurement transmitter in a
measurement range up to 450 l/min with a
frequency output supplies 8 pulses per litre.
Enter "8" as the Factor and "500" as the Up-
per measurem. range. The display is then in
l/min; for the graphical display, the Y-axis is
scaled from 0 to 500.
Examples of count pulses:
1) The switching output of a proximity switch
on a conveyor belt is connected to the fre-
quency input of the HMG 3010. Enter "1" as
the Factor and the expected maximum
quantity to be counted (maximum 30000) as
the Upper measurem. range.
2) A gear flow meter supplies 250 pulses per
liter. Enter "250" as the Factor and as the
Upper measurement range, the maximum
no. of litres expected (maximum 30000).
