General Information
The TVB-2 is a go/no-go load box for verifying that the failure detectors of your Ikonix 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.
Using 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.
To setup a test, connect the high voltage or high current test lead of your electrical safety tester to one of the GC, GB, ACW/DCW, or IR
test points. Connect the return lead to the Return 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-2. 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. Connecting the output leads to a FAIL terminal should result in a FAIL.
Note: pay close attention to the maximum voltage and duty cycle limitations of each resistor. Applying voltages that are
higher than the recommended maximum setting or duty cycles greater than indicated can cause damage to the TVB-2.
Note: attention à la tension maximale et les limites du cycle de travail de chaque résistance. L'application de tensions plus
élevées que le réglage maximum recommandé ou cycles de travail supérieures à celles indiquées peut causer des dommages
à la TVB-2
