In addition,this instrument has the following features.
* 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,Mim imun 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.
* Thermocouple measurement: K indexing, with built-in temperature sensor and automatic cold junction compensation; temperature unit: ℃ or ℉.
* ON/OFF measurement: utter a sound when the measured value is less than 50Ω.
* Large-screen multi-data display: showing the measured values and relevant measurement information at the same time.
* Two easy-to-operate data recording functions: operation recording and manual recording, conducive to the query of recorded data; internal memory: independently store 2,000 (groups of) measurement values.
* Automatic backlight OFF and automatic power OFF.
* Large-screen LCD display with white LED backlight.
* Panel calibration technology: allow calibration without opening the enclosure.
* Battery option: alkaline battery and Ni-Hi battery. The battery compartment door is conducive to the replacement of thebattery and fuse.
* Powerful and user-friendly HMI: for easy access to the stored data, as well as storage, processing and management of data; display form of acquired data: graphic, table, etc.
