General Information:

The TVB-1 is a go/no-go load box for verifying that the failure detectors of your electrical safety compliance tester are functioning 

properly. Use the TVB-1 daily before you begin performing Hipot tests. The TVB-1 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-1. 

Using the TVB-1:

The TVB-1 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 two Red and one Black banana jacks located at the top of the TVB-1 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.

Connect the return lead from the RETURN point of your electrical safety tester to black RETURN point TVB-1.

 

To setup a test, connect the high voltage lead of your electrical safety tester to the red PASS point.

Ensure that the settings on your electrical safety tester are less than or equal to the maximum recommended voltage, current and duty 

cycle settings of the TVB-1. When all connections have been made, press the TEST button to begin the test. With the correct settings 

entered into the electrical safety tester, connecting the output leads to a PASS terminal should result in a PASS.
