True RMS Industrial Multimeter Technical Data
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 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.
ACV Bandwidth
:
50Hz to 1000Hz
Diode Test
:
Test current of 0.9mA maximum, open circuit voltage 2.8V DC typical
Continuity Check
:
Audible signal will sound if the resistance is less than 35Ω
Polarity
