Using a DVOM on low DC scale, negative lead to battery negative terminal, positive lead dipped in coolant at the radiator neck or coolant overflow jug.
Most everyone agree to - A voltage reading of 0.2 volts or less is very good. A reading of 0.5 volts should be considered borderline and anything over 0.7 volts is unacceptable. If the coolant fails this test, the cooling system should be thoroughly flushed and cleaned.
However, at our shop we suggest flushing at 0.4 to 0.5. We do not wait for 0.7.

What does DVOM mean?
It stands for digital volt-ohm meter
90mV on a DVOM meter equals how many volts?

When using a dvom to measure unknown voltage what setting?
Highest setting on the meter.Highest setting on the meter.
How do you check the coolant sensor in a 2003 passat?
You can "test " the sensor using a DVOM ( digital volt ohm meter) if you have a manual that has the spec, also helps to have an inferred temperature gun to confirm the temp at the sensor.
A DVOM is set to the 400 V range If a 12 volt source is measured what will be the meter display?
12 volt
What equipment is needed for testing electrical current?
For measuring electrical Current the electrical equipment used is Amphere meter. This equipment tells the current flow in the equipment.
What is a diode check setting used for on a dvom?
The Diode Check setting on a DVOM is a special ohms setting that presents enough voltage to the tested device to conduct, if it were a diode. Old style VOM's did not have this problem, because they usually used a battery greater than 0.7 volts to run the ohm's scale. Modern DVOM's, however, can use very small voltages to measure ohms, and that would not cause a diode to conduct. The Diode Check setting fixes this limitation.
What antifreeze do you put in 2002 fordfovus zx3?
Check with ford dealer or you can buy antifreeze that mixes w/ any types of antifreeze - but check first or you can cause problems
How do you test for a closed circuit?
continuity test with a multi meter(DVOM), The meter sends a signal(voltage) from 1 lead and if the other lead sees it, the meter will show/chime. A more accurate way is performing a voltage drop, will show if there is a raised resistance due to corrosion or knicked wire/ poor connection.
What does mega mean on a dvom?
One million
How do you test a vrs sensor using a DVOM?
set your DVOM to A/C then back probe both wires- Shop Leader Oloughlin (Wyotech student)
How do you check if my heater core is leaking?
Antifreeze will be leaking in the floorboard on the passenger side, there will be a smell of antifreeze through the vents.
