EXTECH INSTRUMENTS EX570 True RMS Autoranging Multimeter with IR Thermometer

The Extech EX570 Industrial Multimeter with built-in infrared thermometer delivers every multimeter function you need, along with high accuracy and True RMS precision. It is designed to withstand harsh environments and usage with a rugged, double-molded housing. The large, illuminated LCD displays a five-digit readout (to 40,000 counts) and a useful 40-segment bar graph for analog comparisons and quick “needle-swing” tests. The EX570 offers a wide array of must-have multimeter measurements including capacitance, frequency, diode, continuity functions, plus convenient, one-button access to frequently used functions: Min/Max, Average, Hold, Relative, and Peak Hold, as well as selectable auto-ranging or manual-ranging.

dBc
dBc (decibels relative to the carrier) is the power ratio of a signal to a carrier signal, expressed in decibels. If the dBc figure is positive, then the relative signal strength is greater than the carrier signal strength. If the dBc figure is negative, then the relative signal strength is less than carrier signal strength.

Load Regulation
Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply's load (such as a change in resistance value connected across the supply output).

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Settling Time
Settling time of an output device is the time elapsed from the application of an ideal instantaneous step input to the time at which the amplifier output has entered and remained within a specified error band, usually symmetrical about the final value.
