7A501C safety insulation tester carries the Ministry of Power Certificate Number IS1428 (Class 1)and the Factory Inspectorate Certificate Number 2148 (Class 2A and 2C) which covers Methane, Ammonia and Hydrocarbons. The testers have an analogue display and 500V DC insulation test voltage with a short circuit current of less ELECTRICAL INSULATION MΩ Range: 0 - 50M. Test Voltage: 500V DC±10% across 1MΩ Short Circuit Current: <2mA Accuracy: ±1.6mm of scale arc length than 2mA. On continuity the test voltage is nominally 200mV with a short circuit current of 26mA maximum. A special allen key is required to access the batteries so that they may not be changed in a hazardous area. This tester does not comply with The ATEX94 directive. NOTE: BS1259 is now obsolescent and has been superseded by BS5501. Under BS1259 the tester by itself was approved whereas under BS5501 approvals also consider applications of the tester. CONTINUITY Ω Range: 0 - 50. Test Voltage: Nominal 200mV Short Circuit Current: <26mA Accuracy: ±1.6mm of scale arc length Battery: 6 off 1.5V AA IEC R6B MECHANICAL Size: 132 X 82 X 60mm Material: ABS Weight: 0.6kg Movement: Nominal 1.5mA sensitivity - taut band Scale Length: 70mm Test Leads: 1m long with crocodile clips ENVIRONMENTAL Operating Temperature: 0 to 40°C Storage Temperature: -20°C to 60°C Due to policy of continuous development, Martindale Electric reserves the right to alter equipment specification and description outlined in this document without prior notice.
