Test:
1)
Connection, puncture the signal cable and connect to
terminal TPS1 of main connector of HMP1.
2)
Zoom in and out of the magnet repeatedly
while looking at the answer on the screen.
Normally you will see some of following
changes:
A) 0v-12v,
B) 0v-5v,
C) 0v-Open,
D) Pulse - Open.
Pulse implies that the sensor is changed their output since less
of a1 second. For example if you zoom in or out the magnet
recently. The screen remain saying Pulse while you do this
zoom.
Note that the magnet have 2 poles ( north and south), and some
sensors detect this, so if there is no output try invert the magnet,
different angles and zones of sensor.
Logic Probe
This function is special to determine if a wire have voltage,
pulses, ground or simply is disconnected. The measurement is
read from TPS1 input.
In the main menu, use the + and - keys until see LOGIC on
