1An accurate and reliable insulation tester, LCD display,Strong anti-magnetic and anti-jamming function 2Wide measuring range, backlight display, test lock, auto off (only for MAX DC1000V OUT function) and other functions. 3It can also be used for electricity measurement with great advanced appearance, stable performance. Based on straps design, you can operate with both hands. 4Applied in motors, cables, mechanical and electrical equipment, telecommunications equipment, facilities and other insulation testing areas. 5High voltage and short circuit input alarm. Model: VC60B+ Product name : digital insulation tester Sampling rate : About 3 times /second Measurement : Double integral type A / D conversion consumption : consumption of empty load test Less than 300mw Using environment : Temperature 0 -40 , humidity 30% RH-85% RH Over range indication : Only the highest digit shows "1" when the upper limit is exceeded Alarm function : The meter will alarm automatically when the measured is lower than the lower limit of measuring range, and the reading is invalid Dimensions: 175(L)x110(W)x70(D)mm 1WARNING: To avoid electrical shock remove test leads before opening case. 2When changed function and range, the probe should leave the test point. 3Voltage below 36V voltage is the safety voltage. When test 25V AC voltage, please check whether the probe contact safely, whether it is connected properly, whether the insulation is good, etc., for electric shock avoidance.
