Multitester Overview

A multitester, also known as a multimeter, is used for measuring voltage, current, and resistance in various electrical settings.
Common functions include measuring direct current (DC) and alternating current (AC) voltage, resistance, and continuity testing.

Functions of a Multitester

Can test both AC and DC voltage levels.
Measures resistance in ohms.
Checks for continuity in circuits and components.

High Resistance Reading

A high resistance reading typically indicates an open circuit, suggesting no current flow or that the component being tested is functioning properly.

Importance of Correct Range Setting

Setting the correct range on a multitester ensures accurate readings and prevents potential damage to the device or components being tested.
Incorrect range settings can lead to blown fuses or erroneous measurements.

Test Probe Color Codes

Negative test probes are usually associated with the color black.
Red is typically used for positive connections.

Voltage Scale Readings

If the range setting is 50 V, a reading of 1.5 V indicates a relatively low voltage compared to the maximum range.
A reading of 200 V on a 50 V setting would typically appear as an "over range" indication, signaling that the voltage exceeds the selected range.
A voltage reading of 0.01 V signals an extremely low voltage, which is significantly less than the maximum set point of 50 V.
