No matter what type of electrical test equipment you're using, it is extremely important to ensure that your tester's
accuracy is maintained in the period between official calibration procedures by a certified laboratory.
This portable, lightweight and extremely useful calibration checkbox is the easiest, cheapest and most convenient way
to check your electrical test equipment for safety and ensure that drift has not occurred due to damage to the
tester.
Compatible with all electrical test equipment, including multimeters, multifunction testers, RCD testers, voltage
testers and much more, this checkbox can be used to test continuity from 0.5 to 10Ω and insulation from 0.5 to
50mΩ. With direct access to a socket, this calibration checkbox can also be used to test RCD and earth loop
impedance.
We highly recommend using this checkbox both before and after testing procedures to ensure that your tester is in
correct working order.
