Please advise how to measure the voltage output by Model 321343. Also, how is the confirmation of current for the nominal voltage measurements done ?
The voltage output is measured in a null method by connecting Yokogawa Model 270800 Galvanometer between the DC voltage generator which generates DC 1300V and measuring terminal. Confirmation of nominal current of 1mA is available by connecting 500kΩ(= rated voltage/1mA = 500V/1mA) to an ammeter in series. Summaries of JIS C1302: 2002 are as follows. Unless otherwise specified, the testing for insulation testers shall be performed in the following conditions. ・Ambient Temperature: 23℃±5℃ ・Relative Humidity: 45 to 75% ・Position: Vertical (angle of gradient is less than 5°from vertical level) ・External Magnetic Field: None (least effect direction against magnetic field of earth) ・Battery Voltage: Battery effective range * Open circuit voltage test Measuring terminal test at infinite scaleTest is performed by connecting the voltmeter (current consumption is less than 10 μA) between grounding terminal and guard terminal. Please use voltage divider whenever it is required. Tolerance should
