The Instek GDM-8251A benchtop digital multimeter (also called multitester) is a true RMS (root mean square), auto- and manual-ranging meter that measures voltage, current, resistance, frequency, and temperature, and performs continuity and diode 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. The meter can also express AC and DC voltage in decibels (dB), the power ratio of decibels to milliwatts (dBm), and percent of the reading relative to a preset reference value. It also measures 2- and 4-wire resistance. The two-color VFD (vacuum fluorescent display) panel provides contrast and brightness for high visibility in lab and workshop settings. The dual display allows two measurements to be displayed simultaneously. The meter 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. A data hold function keeps a reading on the display for recording. The math mode manipulates readings according to the formula mx + b, where m and b are user-entered constants for scale factor and offset, respectively, and x is the actual reading as would be normally displayed. The meter has a compact profile with a stand that tilts the display up for easier reading or can be folded away to save room. The meter has RS-232C, USB, and digital I/O interfaces that export data to a computer.
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, w
