Microtest

MICROTEST 8740 cable/harness tester utilizes the high end 32Bit True-RMS DSP (digital signal processor) in the measurement technology and is quite different from the ADC (analog to digital converter integrator) that is used in general measurement. Not only promotes the precision with 32-bit data resolution, but also accelerates the AC signal processing to save a lot of times. The AC signal used in wire testing included the capacitance measurement, single-end testing, NG of A / B side judgement, as well as the AC voltage withstand and current leakage, etc. To ensure the stable and precise measurement as well as to save times in AC high voltage processing and leakage current testing. It is twice more faster than CT8681. As adopts the image control function of the embedded processing system, the display screen refresh time only one fourth of that uses the general LCD driver. 8740 USB interface (Figure 1-1) could be used to upload / download the files and store the testing data in the moment of offline. Besides, RS232 interface could be used to connect the computer to do the real-time data processing and monitoring. Moreover, 8740 specially installs the high-voltage and electrostatic protection circuits at each test point which enable to withstand the high voltage shock of itself and the continuous impact of the electrostatic up to 4KV caused by plug in/out at random during testingit completely comply with the regulation of the European industrial electronic products. The tester provides Earphone jack (Figure 1-2), and the sound could be adjusted by selecting System Setup (SYS) / System Environment/choose [5] Sound volume (Figure 1-3) on the option of to avoid causing interference in a noisy environment.
