3.2.1 Ground Speed Calibration
If the operator does not know what the pulses per 400 feet should be, or, if more accuracy is
desired for present levels of tire inflation or soil conditions, the monitor can be put into Pulse
Counting mode, in which the number of pulses associated with 400 feet of driving are
determined.
Measure out a course of 400 feet, preferably on level ground with a start and finish point.
To start the mode, select the SPEED position but instead of going into program mode (with
MODE), hold down the OK key until after the long beep. Display line 1 will show START. To
start the monitor counting the pulses, the MODE key must be pressed. Then the display line 1
will show COUNT and the bottom line will show “0”. The operator can now drive 400 feet and
the monitor will count the number of pulses.
