Ohmeter, resistance measurement
The HMP1 comes with an included ohmmeter that can measure between 2 and 60000 ohms.
It does not intend to replace the tester but we consider it a very useful tool.
1) Connect a test cable to the TPS1 input of the device. But do not make contact with anything.
Warning: make sure that no more than 5v enter before the test
2) Connect the 12v and wait for the menu to appear on the screen.
3) Press the "+" and "-" buttons until you see writing "Ohm ".
4) Press OK and the measured resistance between the tip and ground will appear on the screen.
The word OPEN means that the probe is not connected or that a resistance greater than what the HMP1 can measure is present.
