The Associated Research TVB-2 Test Verification Box is a go/no-go load box for verifying that the failure detectors of your Associated Research electrical safety testing instrument are functioning properly. Use the TVB-2 daily before you begin performing Hipot, Insulation Resistance, Ground Bond and Ground Continuity tests.
The TVB-2 is not intended to comply with any specific safety agency standard.
Note: the trip setting may vary up to 10% of the set value based on the combined tolerances of the instrument and the components used in the TVB-2.
The TVB-2 load box consists of resistors of varying types that induce a PASS or FAIL condition depending on the test parameters that are set in your electrical safety tester.
The 8 banana jacks located on the top of the box can be used to apply the corresponding load to the output of your tester. Each banana jack should be used for a particular type of test, which is outlined on the layout of the load box.
