Milliohm Meter TP-MM3000
Introduction
The Milliohm Meter TP-MM3000 is an instrument used to measure small resistances with high accuracy. The Milliohm Meter TP-
MM3000 measures the resistance by running a current through the components measured upon. Special Kelvin clips are used
to perform a 4-wire sensing measurement, an electrical impedance measuring technique that uses separate pairs of current-
carrying and voltage-sensing electrodes to make more accurate measurements than the simpler and more usual 2-wire sensing.
Separation of current and voltage electrodes eliminates the lead and contact resistance from the measurement. This is an ad-
vantage for precise measurement of low resistance values.
Operating instructions
1. Connect your Automotive Test Scope to the computer and start the measurement software.
2. Set the scope input range to 4 V and select the TP-MM3000 probe for the scope input.
3. Press the Power button (see Power button for more information.)
4. Connect a TP-C1812B differential measuring lead to an input of the Automotive Test Scope.
5. Connect the red and black banana plugs of the TP-C1812B differential measuring lead to the corresponding sockets of the
SCOPE output of the Milliohm Meter TP-MM3000.
6. Connect the kelvin clips to the component of which the resistance needs to be measured.
When measuring an in-circuit resistance, make sure to remove the power from the circuit first, to avoid damaging the
Milliohm Meter TP-MM3000.
Power button
The Power button of the Milliohm Meter TP-MM3000 has three auto power off settings:
Pressed 1 time: the Milliohm Meter TP-MM3000 is swiched off after 10 minutes.
Pressed 2 times: the Milliohm Meter TP-MM3000 is swiched off after 30 minutes.
Pressed 3 times: the Milliohm Meter TP-MM3000 is never swiched off.
The Milliohm Meter TP-MM3000 can always be switched off by pressing the Power button when the instrument is powered on.
Battery
When the battery capacity is no longer adequate the power led will start to blink. Replacing the battery is recommended to keep
resistance measurements accurate.
