Adjustable recording and auto hold thresholds, specify a percentage
change in the readings that begins a new event.
Large 50,000 count, 1/4 VGA dot matrix display with white backlight.
Logging function with expanded memory for unattended monitoring of
signals over time. Using on-board TrendCapture users can graphically review
logged readings without needing a PC. Store up to 15,000 recorded events.
Save multiple logging sessions before PC download is necessary.
Two terminal 50 ohm range with 1 milliohm resolution, 10 mA source current.
Useful for measuring and comparing differences in motor winding resistance
or contact resistance.
On board help screens for measurement functions. Unsure about a function
- go to that function and press the "i" button.
Real time clock for automatic time stamping of saved readings.
Relative mode to remove test lead resistance from low ohms or capacitance measurements.
True-RMS AC voltage and current for accurate measurements on non-linear signals.
Measure up to 10 A (20 A for 30 seconds).
100 mF capacitance range.
Peak capture to record transients as fast as 250 μs.
Premium test leads and alligator clips included.
Amp jack plugs included.
Optional magnetic hanger for easy setup and viewing while freeing
your hands for other tasks.
FlukeView forms enable you to document, store and analyze individual
readings or a series of measurements, then convert them into professional-looking documents.
Limited lifetime warranty.

How to Measure Resistanca using Digital Multimeter - DMM?
Normal resistors have color codes on them. If you don’t know what they mean, that’s ok! There are plenty of online calculators that are easy to use. However, if you ever find yourself without internet access, a multimeter is very handy at measuring resistance.
Pick out a random resistor and set the multimeter to the 20kΩ setting. Then hold the probes against the resistor legs with the same amount of pressure you when pressing a key on a keyboard
The meter will read one of three things, 0.00, 1, or the actual resistor value.
In this case, the meter reads 0.97, meaning this resistor has a value of 970Ω, or about 1kΩ (remember you are in the 20kΩ or 20,000 Ohm mode so you need to move the decimal three places to the right or 970 Ohms).
If the multimeter reads 1 or displays OL, it’s overloaded. You will need to try a higher mode such as 200kΩ mode or 2MΩ (megaohm) mode. There is no harm if this happen, it simply means the range knob needs to be adjusted.
If the multimeter reads 0.00 or nearly zero, then you need to lower the mode to 2kΩ or 200Ω.
Remember that many resistors have a 5% tolerance. This means that the color codes may indicate 10,000 Ohms (10kΩ), but because of discrepancies in the manufacturing process a 10kΩ resistor could be as low as 9.5kΩ or as high as 10.5kΩ. Don’t worry, it’ll work just fine as a pull-up or general resistor.
