Counting
Counting is used to count events by using:
One digital switch type sensor connected to either input A or input B
Two digital switch type sensors connected to both input A and input B
The up
▲
(A) or down
▼
(B) buttons on V-Log.
If plug-in sensors are connected, the logger will automatically count using input from those sensors.
Press to cycle through simple mathematical functions on the A and B data (A + B, A
– B, B – A,
Difference
).
1. If you are using plug-in digital sensors connect them to input A and/or B. If the display is turned off,
press any button to wake up the logger
.
2. While in the main menu use the up or down buttons
▲▼
to scroll until the cursor is pointing at
Counting
. Press the enter button
►
to select.
3. If you are using plug-in digital sensors each time the state of the sensor is changed to On e.g. by
pressing a push switch, the number of counts will advanced by one.
If the scroll buttons on V-Log
▲▼
are used then the count will increase by one each time you press a
button. You can use either one or both buttons e.g. use the
▲
button to count people entering a room
and
▼
to count those leaving.
V-Log will display both the numeric value and show it as a bar graph. The bar maximum starts as 10,
if the count goes above 10 it will increase to 20, then 50, 100, 250, 500, up to a maximum of 1,000.
Note:
If V-Log
goes into ‘sleep’ mode during logging, press any button to wake it up.
If counts are from both A and B pressing the enter button
►
will cycle through simple calculations
based on the counting data (e.g. A + B = 13, A
– B = -3, B – A = 3, Difference = 3).
4. Press the stop
button to finish and then enter
►
to confirm your choice.
The count will be stored as a data set identifiable by the method and time and date the recording was
started e.g. Counting 09/05/12 16:12:43. Up to 999 samples can be stored in one data set.
