previously) every time there is a meter contact closure. At the first contact
closure, the
PVD100
outputs the first contact closure as the start of the
measurement. The number of meter contact closures begins with “zero” and the
counts of elapsed time begins with “zero.” Contact closures and counts of
elapsed time will begin to increment following every contact closure until the
“
A
” command is sent or the SELECT button is pressed. The
PVD100
then
sends the final data string (in decimal) followed by the
PVD100
reinitializing.
The character ‘A’ is sent when the
PVD100
completes a calibration cycle, as it
initializes.
Sending the ‘
I
’ command anytime before or during the test aborts (or quits) the “Spin
Test” function. The
PVD100
sends the character ‘
A
’ to acknowledge exiting. When the
PVD100
exits, the
PVD100
reinitializes with a calibration. When the calibration has
been completed, the
PVD100
sends the character ‘
A
’ again, and then goes to normal
operation mode.
