On a traditional analog multimeter, there is a screw on the face of the meter to adjust the tension on the pointer. It lets you set the pointer to zero when there is no current, just like zeroing the bathroom scales before you step on them.
You check and adjust instrument zero and, if you are measuring ohms, you also check and adjust ohms zero.
In a multimeter, "OL" stands for "Over Limit" or "Open Loop." It indicates that the measurement exceeds the range of the multimeter, such as when measuring resistance in an open circuit or when the voltage is too high for the selected range. Essentially, it signifies that the reading is outside the device's capability to measure accurately. If you see "OL," it's advisable to adjust the multimeter settings accordingly.
Example: int x; -- integer int *px= &x; -- pointer to integer int **ppx= &px; -- pointer to pointer to integer int ***pppx= &ppx; -- pointer to pointer to pointer to integer
Pointer to Pointer is a double pointer, denoted by (**). Pointer stores the address of the variable and pointer to pointer stores the address of a pointer variable and syntax can be given as int **ptr2ptr;
When a variable is declared as being a pointer to type void it is known as a generic pointer. Since you cannot have a variable of type void, the pointer will not point to any data and therefore cannot be dereferenced. It is still a pointer though, to use it you just have to cast it to another kind of pointer first. Hence the term Generic pointer.
To check the IC by the multimeter, you have to make sure that the pointer points at the current. You can then connect the multimeter across the check the IC.
Analog multimeters use a microammeter with a moving pointer to display readings
You check and adjust instrument zero and, if you are measuring ohms, you also check and adjust ohms zero.

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.
To adjust one's screen resolution on a Windows computer, right click on the mouse when the pointer is over the homescreen. Press "adjust screen resolution" and adjust to one's needs.
To move the pointer on a microscope, you can adjust the mechanical stage controls that move the slide horizontally and vertically. Simply turn the knobs in the desired direction to position the pointer over the area of interest on the specimen slide.
The pointer on a thermostat moves when the room temperature changes. This change in temperature causes the thermostat's sensor to detect the difference and adjust the pointer accordingly to indicate the new temperature reading.
In a multimeter, "OL" stands for "Over Limit" or "Open Loop." It indicates that the measurement exceeds the range of the multimeter, such as when measuring resistance in an open circuit or when the voltage is too high for the selected range. Essentially, it signifies that the reading is outside the device's capability to measure accurately. If you see "OL," it's advisable to adjust the multimeter settings accordingly.
When after you adjust the riders and the pointer reads zero
To test voltage accurately and effectively using a multimeter, follow these steps: Set the multimeter to the voltage setting that is higher than the expected voltage to be measured. Connect the black probe to the common (COM) port and the red probe to the voltage (V) port on the multimeter. Touch the probes to the circuit or component being tested, ensuring proper contact. Read the voltage displayed on the multimeter screen. If needed, adjust the multimeter setting to a lower range for a more precise measurement. Always ensure the multimeter is properly calibrated and in good working condition for accurate results.
To change the shape of the pointer in a user interface, you can typically modify the cursor property in CSS for web-based interfaces or adjust the cursor settings in the operating system for desktop applications. You can choose from a variety of built-in cursor shapes or create your custom cursor design.
