tester\u003c\/strong\u003e designed for electrical insulation checks, troubleshooting, equipment commissioning and preventive maintenance. It provides two insulation test voltages, \u003cstrong\u003e500V and 1000V DC\u003c\/strong\u003e, with insulation resistance measurement capability up to \u003cstrong\u003e2000 MΩ\u003c\/strong\u003e. The tester also measures \u003cstrong\u003eAC\/DC voltage up to 600V\u003c\/strong\u003e and supports low-resistance earth-bond measurements up to \u003cstrong\u003e20.00 kΩ\u003c\/strong\u003e. For additional protection, the instrument detects energized circuits and inhibits insulation testing when terminal voltage exceeds \u003cstrong\u003e30V\u003c\/strong\u003e. An automatic discharge function helps remove stored capacitive voltage after insulation measurements. Its large backlit digital display, remote test probe support and portable battery-powered design make it suitable for electrical field servicing. The instrument carries a manufacturer-specified \u003cstrong\u003eCAT IV 600V\u003c\/strong\u003e safety classification. Supplied photographs show a \u003cstrong\u003eFluke 1503\u003c\/strong\u003e instrument together with test accessories and user documentation.

1535\u003c\/strong\u003e is a \u003cstrong\u003e2500V digital insulation resistance tester\u003c\/strong\u003e manufactured by Fluke Corporation for industrial electrical maintenance, insulation condition assessment and equipment troubleshooting. It provides selectable insulation test voltages of \u003cstrong\u003e250V, 500V, 1000V and 2500V DC\u003c\/strong\u003e, with a maximum insulation resistance measurement range of \u003cstrong\u003e500GΩ at 2500V\u003c\/strong\u003e. The instrument supports automatic \u003cstrong\u003ePolarization Index (PI)\u003c\/strong\u003e and \u003cstrong\u003eDielectric Absorption Ratio (DAR)\u003c\/strong\u003e calculations for evaluating insulation condition. The Fluke 1535 includes an energized circuit warning for voltages above 30V and automatic capacitive discharge functionality following insulation testing. It has a manufacturer-specified \u003cstrong\u003eCAT IV 600V safety rating\u003c\/strong\u003e, an \u003cstrong\u003eIP40 enclosure\u003c\/strong\u003e, and uses eight AA alkaline batteries. Its portable design is intended for insulation resistance testing of suitable electrical equipment, including motors, cables and industrial electrical systems. The actual photographs show the \u003cstrong\u003eFluke 1535\u003c\/strong\u003e instrument and a carton labeled \u003cstrong\u003eFLUKE-1535\/CN\u003c\/strong\u003e.

number \u003cstrong\u003e4325155\u003c\/strong\u003e, is a professional GEO earth ground resistance tester for electrical grounding system measurements. The instrument supports traditional 3-pole and 4-pole ground resistance testing, selective clamp-assisted measurements and stakeless ground loop testing when the required compatible accessories are used. It offers a backlit LCD, internal memory for up to 1500 records and USB data transfer. The rugged protective housing is specified as IP56, while the battery compartment door is rated IP40.
