This checkbox can withstand 1000Vdc insulation tests, and  provides measurements within 1% of values stated

The sockets provided on this checkbox are compatible with lantern type probes found on most modern test leads

The benefits of using these sockets are:

  • Consistent meter readings time after time

  • No exposure to 500-1000V test voltages

  • Hands free for pressing the test button & recording readings

Two green zero sockets are provided to quickly null meter lead resistance

Readings are then taken between green and blue sockets for continuity ranges, or green and red sockets for insulation ranges

Precise meter readings can also be written on the back of the checkbox making it handy on-site
