Rate
The Rate setting controls how often the DataCollector takes measurements in
Standard Mode. The DataCollector has rates from 1 - 2,000 Hz. The default rate
setting is 1 Hz. Tap the down arrow to see the drop-down menu of sampling rates
and make a selection. The sampling rate is indicated in the status bar of Data Col-
lection Mode.
If you are operating in Interval Mode, the rate will read “N/A”.
Sensor 1 & Sensor 2
The DataCollector automatically detects and identifies sensors when they are
plugged in. If a sensor is plugged into the Sensor 1 port, its name will appear next
to Sensor 1 in the Setup Window. The default units for the sensor will also appear.
The units can be changed by tapping the down arrow and selecting alternative
units.
To turn the sensor off, select “None” from the drop-down menu.
If no sensor is plugged in, it will read “None”.
Photogate A & Photogate B
The DataCollector automatically detects when photogates are plugged in. If a pho-
togate is plugged into the Photogate A or Photogate B port, you may select the
function of the photogate from the drop-down menu. Or, you may select to turn
the photogate off by selecting “None”.
If you have chosen to operate in Standard Mode, you may select one of the follow-
ing functions from the drop-down menu: Period, Frequency or Count. For
detailed information on these functions, see “CPO Timer Mode” on page 17.
If you have chosen to operate in Interval Mode, you must use the Interval function.
If no photogates are plugged in, “None” will be displayed.
