*  Measurement display: max. 55,000, with a basic accuracy of0.025%.
 *  Dual-color plastic module enclosure: comply with Class IP65 requirements for dustproof and waterproof protection, so this instrument can be used in a harsh environment.
 *  Conform to the 600V CAT.IV and 1000V CAT.III safety standards of the Safety Requirements for Electrical Equipment for
Measurement, Control and Laboratory Use (IEC 61010-1).
 *  Protection of current measurement: 10A/1000V & 0.5A/1000V fast-acting fuse.
 *  Infrared USB communication.
 *  Range options: manual and automatic.
 *  Functions for measurement data: DIS_HOLD and AUTO_HOLD.
 *  PEAK function: 1ms peak sample capture. This instrument is able to capture spike pulses.
 *  Measurement (dB) of reference impedance: 1-2400Ω.
 *  Relative value measurement: (REL_%).
 *  Maximum, minimum, and average measurement (MAX/MIN/AVG).
 *  Display rate: 20 times per second (fast) and 5 times per second (slow); simulation bar refresh rate: 20 times per second
(fast).
 *  AC true RMS measurement: 20Hz to 50kHz. 

*  Low-pass filter: improve the measurement of composite waveforms typically produced by inverters and variable frequency motors.
