It’s faster to isolate brake problems

when you can see the caliper,

hub, and rotor in a single pic-

ture. You could spot brake drag,

for example. Establish baseline

images for predictive maintenance

by using the visual IR thermometer

during routine road tests.

Get a fresh look at automotive troubleshooting with a revolutionary

new tool category that empowers you to go right to the hot or cold

spots with blended visual and thermal heat map images.

With the VT02 Visual IR Thermometer, you can perform inspections

significantly faster than with traditional IR thermometers and see what

you are measuring.

1. Brakes

]

Typical heat generated from the

brake rotor.

Heat generated from brake pads at

the caliper area.

Set yourself up for success. Follow a few

simple steps that will help ensure a more accurate

reading in these top 10 applications:

• Have direct access to the target you are measur-

ing. Disassembly may be required around your

target.

• When you’ve found a potential issue using the

blended heat map, move closer to take a center-

point temperature measurement. The exclusive

Near/Far feature in the VT02 allows you to get

as close as six inches with thermal heat map

images that are accurately aligned.

• Establish baseline temperatures in your most

common applications so that an unusual read-

ing can help you predict that something may be

wrong.

• Understand temperature characteristics such as

emissivity which can influence your readings.

Proof is in the picture. The SmartView

software

included with your VT02 purchase is a smart way

to document both the diagnosis and repair as well

as expand your business. It’s important proof for

customers and managers.

Eliminate the guesswork and get started today.

The time savings will amaze you.

[ 2. Air conditioning systems ] With the VT02, you can verify that an A/C line is functioning properly or diagnose the problem if the line is blocked. You can also easily compare register output to verify overall system performance. Normally functioning A/C orifice. Cold register. Hot register. [ 3. Thermostats ] By watching hose temperatures during warm-up, you can test whether the thermostat is working properly. Thermostat during warm-up. 2 Fluke Corporation Thermostat just after opening.

[ 4. Engine noise ] A complaint of intermittent engine noise can be difficult to verify. As a part of routine predictive maintenance, you could determine that the perceived belt noise is actually a result of decoupler pulley slippage, and replace it before total decoupler failure occurs. Normally functioning pulley. Pulley with abnormal friction. [ 5. Condensers ] Measure the cooling capacity of the condenser, or quickly scan the whole condenser for hot or cold spots.

[ 6. Diesel engine performance ] Monitor diesel engine performance with the VT02 by checking exhaust manifold temperatures to help determine cylinder efficiency. For example, in these images, one cylinder is not generating as much heat through the exhaust port as the other three. This could indicate a potential problem with that cylinder, which merits further inspection. Output of 2 typical cylinders. Output of 1 typical and 1 potentially weak cylinder. [ 7.

[ 8. Rear defrosters ] With a quick scan of the rear window, you can verify that the entire defroster grid works properly. Defroster warming up. Normally functioning defroster grid. [ 9. Solenoids ] For a solenoid that controls auxiliary equipment, you can see at a glance whether it’s on, and if there’s any heat build up where there shouldn’t be. For example, the heat at this output terminal where a crimp lug was installed could indicate a loose connection that is worth investigating.

[ 10. Parasitic draw ] This radio was diagnosed without pulling it out of the dash. With the key turned-off, the left side indicated current draw draining the battery, warranting further investigation with a current clamp. The diagnosis proved to be a defective radio. Malfunctioning radio. For product specifications and more information about the VT02 visit www.fluke.com/VT02 Fluke.
