Test
Using the Function button scroll to the “Spin ?” menu and
press SELECT to move the arrow to Yes, and then press the
ON/OFF button to enter the spin function.
This opening display for the special function called ‘SPIN
TEST’ is shown. A ‘spin test’ is an elapsed time measurement
from the time a meter is spun to when rotation of the meter
stops. The operator controls the start and stop time for a total
elapsed time measurement. The test measures total elapsed
time and total number of meter counts detected. Start and stop time is controlled by
depressing the ‘
Select
’ button. Perform the following steps to ‘spin test’ a meter:
1. Before selecting the ‘SPIN TEST’ function, select the type of meter contact, i.e. cat
whisker head contact or magnetic head contact.
2. From the opening display presentation as shown above, depress the ‘SELECT’
button.
3. Spin the meter. When the
PVD100
detects the first contact closure (which is not
counted) the elapsed time counts begins. Each following contact closure detected
is counted and shown on the top line of the display. The bottom line of the display
shows the continuing elapsed time in seconds. When the
meter stops rotating, depress the ‘SELECT’ button again.
The display presentation shown in the figure on the left gives
the final summary of the total number of contact closures
detected and total elapsed time in seconds. Maximum
number of elapsed time is 999 seconds and the maximum
total number of meter counts that is displayed is 999.
4. To exit from the ‘SPIN TEST’ function at any time, depress the ON/OFF button.
The
PVD100
will exit from the function; perform a calibration, and then return to
the Main display.

While the Spin Test is in progress, serial data is automatically transmitted on
the serial port. See
