OL means the
light intesity is out of the measurement range
. … For example, if you are trying to measure a light putting out 20,000 fc, but your range is set to 2000 (or 200) you will get “OL” on the display. The reason range matters is the device will be more accurate in a smaller range.
What does OL mean on Megger?
If your megohmmeter is reading “OL” (
over load
) or “I” (infinity), these are commonly used readings on megohmmeters when the measurement exceeds the maximum indicated value of the tester.
What does it mean if the display shows OL?
This is a common misunderstanding but OL means
open line
. It means that what is being measured is not making it’s way from black probe to red probe. You will always see this in diode mode, ohm mode and continuity mode when the probes are not touching each other / not connected.
What does it mean when a capacitor reads OL?
An “OL” or “overload” reading means
the capacitance is too high for the multimeter to measure
. Set the multimeter to a higher range if possible. This result can also mean the capacitor has shorted. … You may see “OL” appear on the screen multiple times before you see the final result.
When a meter shows OL It means the meter is being damaged?
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.
Does Ol mean infinite resistance?
Infinite resistance (open circuit) is read as “OL” on the Fluke meter display, and means
the resistance is greater than the meter can measure
. Resistance measurements must be made with the circuit power off – otherwise, the meter or circuit could be damaged.
What does a 0 ohm reading mean?
Resistance, symbolized by the (Ω) symbol and measured in Ohms, is a measurement of how well a current can travel through a circuit or a given path. A circuit with no resistance (0) would indicate
a complete circuit
, or one that has no short.
What is a bad reading on a Megger?
What is a bad reading on a Megger test? If the
megger reads a resistance under 1 (1,000 ohms) on your meter after the initial 60-second interval
, the cable has failed and the cable should be removed. If the megger reads a resistance between 1-1.25 on your meter, then the cable passes.
What is infinity in Megger?
When the pointer of the PMMC instrument deflects towards infinity, it means that
the voltage coil remains in the weak magnetic field and thus experienced the very little torque
. The torque experienced by the coil increases when it moves insides the strong magnetic field.
What does infinity mean on a Megger?
When an ohmmeter points to the infinity symbol, it means that
there is no continuity between the two test leads and that an open circuit is present.
How do I know if a capacitor is bad?
- AC Not Blowing Cold Air. An air conditioner that doesn’t blow cold air is one of the first signs of a problem many homeowners notice. …
- High and Rising Energy Bills. …
- Humming Noise. …
- Old HVAC System. …
- AC Turns Off On Its Own. …
- AC Doesn’t Turn On Immediately. …
- AC Won’t Turn On.
How do you test if a capacitor is bad?
Use the multimeter and read the voltage on the capacitor leads
. The voltage should read near 9 volts. The voltage will discharge rapidly to 0V because the capacitor is discharging through the multimeter. If the capacitor will not retain that voltage, it is defective and should be replaced.
What is an ohm test?
This test, using a digital multimeter, determines whether:
an electrical circuit is complete or broken
.
the resistance of a component matches the manufacturer’s specification
.
How do you read a 20K ohm meter?
The ohm setting on the multimeter give you the maximum
ohm it can
measure up to. For example, 2k (0 to 2000 ohm), 20K (0 to 20,000 ohm), 200K (200,000 ohm), 2m (0 to . 002 ohm).
How do you know if a resistor is bad?
- Turn off the power running through the circuit containing the resistor you need to test. …
- Look at the color bands around the barrels of the components for the code to determine resistor values. …
- Check resistor values with the color codes.
