MT1887
The MT1887 measures true-rms AC voltage and current
readings, that yields accurate results on sine waves as
well as non-sinusoidal waveforms using a frequency
range of 50Hz to 1kHz. The MT1887 has a large LCD
display screen where the accuracy is stated in 40,000
high resolution counts, supported with a 41 segment
analogue bargraph and white back light, ideal for use in
dimly lit areas. The MT1887 is an ideal tool for
troubleshooting power distribution, industrial
automations and for electronic and electrical field
applications. This popular meter is also available in an
intrinsically safe version.

AC Response
:
True rms
AC True RMS
:
The term stands for "Root Mean Square", which represents the method of calculation of the voltage or current value. Average responding
multimeters are calculated to read correctly only on sine waves and they will read inaccurately on non-sine wave or distorted signals.
True rms meters read acurately on either type of signal.
