TP-MM3000 4 Channel Differential Input Automotive USB
Milliohm Meter TP-MM3000
Introduction
The Milliohm Meter TP-MM3000 is a device used to measure resistance in
automotive circuits. It has an input range of 0-2.5 and an accuracy of 1%. The
output ratio is 1 m = 1 mV and the output voltage varies depending on the
resistance measured, with a maximum of 2.65 V. The device comes with kelvin
clips on 85 cm leads and 4 mm banana sockets. It operates at an operating
temperature of 25 C and requires a 9 V PP3 battery for power.
Operating Instructions
- Connect your Automotive Test Scope to the computer and start the measurement software.
- Set the scope input range to 4 V and select the TP-MM3000 probe for the scope input.
- Press the Power button (see Power button for more information.)
- Connect a TP-C1812B differential measuring lead to an input of the Automotive Test Scope.
- 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.
- 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. The device can always be switched off by pressing the Power button when the instrument is powered on.
- Pressed 1 time: the Milliohm Meter TP-MM3000 is switched off after 10 minutes.
- Pressed 2 times: the Milliohm Meter TP-MM3000 is switched off after 30 minutes.
- Pressed 3 times: the Milliohm Meter TP-MM3000 is never switched 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.
