SEW 6211A High Voltage Digital Insulation Tester. It measures insulation resistance in electrical systems to ensure safety and prevent hazards. Key features and instructions include:
Measurement:
Measures insulation resistance using test voltages of 10kV, 5kV, 2.5kV, and 1kV.
Safety:
Use only on de-energized systems.
Always earth the circuit under test.
Check test leads for defects before use.
Operation:
Connect leads observing color coding.
Select the appropriate test voltage.
Apply the red lead to the conductor under test.
The display shows test duration and insulation resistance.
Additional Features:
Auto-ranging and auto-off functions.
Integral guard circuitry to minimize errors from surface leakage.
Enersave mode for low consumption and reduced test duration.
Microprocessor controlled.
