Ideal Industries 61-342 Test-Pro Digital Multimeter with TRMS

The Ideal Industries 61-342 digital multimeter (also called multitester) is a true RMS, auto- and manual-ranging meter that measures voltage, current, resistance, duty cycle, capacitance, frequency, and temperature, and performs diode and continuity tests in electrical applications. An audible continuity sensor confirms a circuit conducts electricity, and a diode test detects proper functioning of a circuit's diodes. Fused current ranges protect the meter in high-energy environments. Temperature measurements are taken using a K-type thermocouple. The LCD is backlit for use in low lighting and updates readings 2.5 times per second. It displays the present measurement or the minimum (Min) and maximum (Max) reading in a session, for tracking sudden changes in readings. Relative mode displays the difference between the measuring value and the user-defined reference value. Relative mode is helpful when comparing two readings or removing test lead resistance from low-ohm measurements. The unit automatically turns off after 10 minutes of nonuse to conserve battery life, and a low-battery indicator signals when the meter's batteries need to be replaced.

This true RMS (root mean square) meter provides accurate readings when measuring linear loads, such as standard induction motors and incandescent lights, where the current or voltage has an undistorted waveform, or nonlinear loads, such as electronic devices or motors, where the current or voltage has a distorted waveform. When turned on, the meter is in auto-ranging mode and automatically selects the correct operating range for the property being measured. It can be switched to manual-ranging mode, which allows the operator to choose the appropriate operating range. The LCD has a 4,000-count resolution, meaning it can display up to 3,999 units (3-3/4 digits) before the operating range needs to be changed. The meter meets International Electrotechnical Commission (IEC) safety standard 61010 and is certified for Category III installations up to 600V, which covers items used with enclosed building circuit installations (such as service panel parts, branch circuits, and fixed installations that are connected directly to a building's AC power supply) and Pollution Degree 2 for indoor use. The meter includes test leads, one 9V battery, and instructions.

Specifications

H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Multimeters are electrical test meters that measure multiple properties of an electrical circuit, such as current, voltage, resistance, capacitance, and continuity. Available in handheld or benchtop models, multimeters diagnose electrical problems in electrical equipment, wiring, and power supplies. A variety of probes, clamps, and leads can be used to connect the meter to a circuit or device. Multimeters display information either in analog or digital form. Factors that influence meter choice include the electrical properties to be measured, the anticipated range of results, and the desired level of protection against transient voltage. Safety ratings are based on International Electrotechnical Commission (IEC) standards for low-voltage test equipment. IEC 61010 delineates four overvoltage installation categories. In general, a meter with a category IV rating will provide more protection against transient voltages than a meter with a lower category rating.

Ideal Industries manufactures test and measurement equipment, electrical supplies, and tools, among other products. The company, founded in 1916, is headquartered in Sycamore, IL.
