Transformer Winding Resistance Meter
1 Piece (MOQ)
We are offering transformer winding resistance meter. The nmc 'tdr' is a high precision, new generation, light weight large output current and micro-processor controlled tester. This replaces old dc wheat stone bridge and double arm bridge for measurement of dc resistance. 'tdr' adopts new advanced test current power supply technology,four terminal measurement, digital display of resistance value and test current. 'tdr' ispowered by 220v ac mains single phase supply. The measurements are accurate as the test current is highly stable. High automation is achieved with automatic discharge warning. principle: the constant current generated is fed to the resistance under test through the current terminals and the voltage drop across the resistance under test is measured and displayed in ohms. A true four terminal measurement is used to eliminate the need for lead resistance compensation. features : >> constant current source>> saves 255 test results in memory>> built-in printer description: nmc 'tdr' is a new generation, digital resistance meter using 4 terminal measurement technique. Built in printer for printing results. The entire test is done quickly. 'tdr' generates constant current, powers up the test current, takes the readings, and displays the results on the lcd screen. The 'tdr' is encased in an aluminum alloy cabinet. 3 models available : tdr-10 , tdr-20 , tdr-40.
