It usually stands for open loop, another way of saying there isn't continuity.
Original answer: it means OVER-LIMIT
beyond the limits of the meter to register, such as "infinity" on a resistance scale

List the two types of multimeter?
digital and analog
What are disadvantages of a digital multimeter?
The main advantage of a digital multimeter over an analog multimeter is their accuracy.AnswerDigital instruments are not necessarily more accurate than analogue instruments (although they often are), but they are far more robust and, usually, far easier to read without error. A digital multimeter has no moving parts and is unaffected by gravity, so they can be used at any angle, whereas analogue instruments needed to be placed on horizontal surfaces and not subjected to vibration.
What is the working principle of DMM?
a digital multimeter uses similar input circuits to those used in an analog multimeter for the various scales, but uses a dual slope integrating analog to digital converter to get a precise digital value of four or five digits to display. this type of analog to digital converter is slow but very precise, also though slow it is more than fast enough for a human to not perceive the slowness.
Function block diagram of the digital multimeter?
A digital multi meter is what is used to find electric current. A block diagram shows all of the working parts of the multi meter and how they are connected.
What instrument measures voltage?
Resistance is measured with an ohmmeter. A link is provided to a brief article on the ohmmeter posted at Wikipedia.Note that it is unusual in this day and age to have a device that will measure ohms and nothing else. The ohmmeter is usually included among the functions of a multimeter, and usually a digital multimeter or DMM.
When measuring resistance with a Digital multimeter what does the flashing display indicate?
contact was made.
What does the voltage on a digital multimeter indicate?
It generally reads RMS value of the voltage being measured
Meaning of multimeter reading 'OL'?
OL refers to over limit.
What are the types of multi tester?
A Multimeter is an electronic instrument, every electronic technician and engineer’s widely used piece of test equipment. A multimeter is mainly used to measure the three basic electrical characteristics of voltage, current, and resistance. There are two types of multimeters: Analog Multimeter: The Analog Multimeter or VOM (Volt-Ohm-Milliammeter) is constructed using a moving coil meter and a pointer to indicate the reading on the scale. Digital Multimeter: We mostly used a multimeter is a digital multimeter (DMM). The DMM performs all functions from AC to DC other than analog. It has two probes positive and negative indicated with black and red color as shown in the figure. there are some best multimeters for HVAC.
Is an electronic multimeter a digital or analog?

Who has a wide range digital or analog multimeter?
The analog multimeter has a wider range.
What to do if the digital multimeter is faulty?

When testing for current draw your digital multimeter should be set on?
When testing the current draw your digital multimeter should be set on the current.
How many volts takes multimeter?
In Digital multimeter we use 9V Dc battery.
Low voltage in a Digital Multimeter is?
Unfortunate.
What do the digits refer to in a digital multimeter?
value of measurements
What are the theories of a digital multimeter?
buried with einstein. amen
