HDE PT-5000W, Руководство по эксплуатации и инструкция, Страница: 3 / 8

OPERATING INSTRUCTIONS
WARNING: Always wear high voltage gloves rated for the planned test. For a 500V
test class 00 or better high voltage gloves are required. For a 5,000V test, class 1 or
better high voltage gloves are required. Before using this tool, ensure that the
equipment to be tested is both deenergized and discharged. This tool may leave
a high voltage charge on tested equipment. Following each test, leave the tool
connected for 30 seconds to allow this equipment to discharge.
1) Connect one of the two clips to ground. Connect the other clip to the equipment
to be tested.
2) Select the test voltage. Press and hold the ONE left button to select 500VDC.
Press and hold BOTH buttons simultaneously to select 5,000VDC.
3) Indicator lights verify the selected test voltage and confirm the battery
condition is OK.
4) Leakage current, if any, is indicated for either 100 or 1,000 microamps
depending on the voltage range selected. Equipment with a substantial
capacitance such as long cables or power factor correction capacitors may
indicate leakage current when first energized. If the equipment is in good
condition, these leakage current indications will disappear as the equipment
is charged.
APPLICATIONS
The PT-5000W is a general purpose insulation tester for both primary voltage and
secondary voltage insulation systems and components. Most important is that the
proper voltage is selected for the system or components to be tested. For secondary
voltage systems rated to 600V select the 500VDC test range.
Testing secondary voltage systems or components with 5,000VDC may result
in permanent damage to the systems or components being tested. For primary
voltage systems either the 500VDC or 5,000VDC range may be selected but the
5,000VDC range will be both a more rigorous and more sensitive test since the
5,000VDC range automatically selects the lower leakage current indication
threshold of 100 microamps.
