KPS MA500 – 5KV Insulation Resistance Tester
| Features | |
| * | Broad Range of Testing Voltage : |
| – | Testing voltages with broad range can be generated (from 250 V to 5 KV). |
| – | Testing voltage can be preset as 250 V, 500 V, 1 KV, 2.5 KV, or 5 KV, or as a voltage increasing or decreasing in steps of 25 V or 100 V. |
| * | Insulation Diagnosis : |
| – | PI and DAR can be automatically calculated and displayed; |
| – | Step-voltage measurements and temperature compensation is carried out. |
| * | Large Storage Memory : |
| – | Up to 100 manually tested data and 10 groups of log-test data can be saved. |
| – | Test data can be read on LCD, or uploaded to PC |
| * | Clear Display : |
| – | Large-screen display. Test result is displayed with indication through a graduation bar. |
| – | LCD screen is backlit, which is suitable for viewing when it is dark. |
| * | PC Communication : |
| – | The meter is equipped with a USB interface, through which the saved test data can be uploaded to a PC for further table/figure making and report generating with convenience. |
| * | Robust and Durable : |
| – | With a compact structure, the tester is robust, durable and portable. |
| * | Powered by Batteries : |
| – | With a selection switch, the tester can be powered by an alkaline battery. |
| – | This tester can be continuously operated for a longer period of time than similar meters if a LR14 alkaline battery is used. |
