Lightning Protection Component Tester Insulation Resistance Tester 0.5 to 3000MOhm MOV GDT Tester Touch Color Screen ETCR3800B 1.Introduction: ETCR3800 series intelligent lightning protection component tester is used to measure the performance parameters of various metal oxide varistors (MOV) and Gas discharge tubes (GDT).  ETCR3800B also has the function of insulation resistance test. The tester has high-voltage short-circuit protection, over-current protection, high-voltage presetting, range adjustment, self-inspection function, measurement range of spark voltage U1mA: 0~2000V, measurement range of leakage current: 0~ 499.9μa, good repeatability.It also has the function of setting up qualified range and judging and screening qualified products.Widely used in lightning protection component, surge protectorand other over voltage protection components performance parameters test. The instrument adopts touch color screen, direct function, one-button measurement, easy and fast operation, with excellent test stability and anti-interference ability.At the same time, the meter is build in a large capacity rechargeable lithium battery, and with data storage, qualified judgment, automatic shutdown, USB data upload and other functions. ETCR3800 series lightning components tester has shockproof, dustproof, moisture-proof structure, the whole machine is beautiful and durable, adapt to bad working environment.It is the commonly used necessary instruments in the lightning protection, power, communication, electromechanical installation and maintenance, lightning protection components manufacturers, and industrial enterprise departments. 2.Type series:       Product model    MOV test    GDT test    Insulation resistance test        ETCR3800B    Yes    Yes    Yes            3.Range and measurement accuracy:           Functions     Iteam     Measuring range     Accuracy of measurement     Resolution           MOV     voltage 0~2100V     20~2000V     ±2% RDG 3 DGT     1 v           current 0~1.5mA     0~1000μA     ±2% RDG 10 DGT     0.1 μA           GDT     voltage0~2100V/1.5mA     20~2000V     ±2% RDG 3 DGT     1 v           *Insulation resistance     500 v     0.5MΩ~3000MΩ     ±3% RDG 10 DGT     0.1 M         Test conditions:            MOV: 1mA + 5 μ A;  GDT: 100V/S  * Insulation resistance test function is limited to ETCR3800B only 4.Technical Parameters:       Battery    DC 7.
