General Information
The TVB-1 is a go/no-go load box for verifying that the failure detectors of your Slaughter 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 specic 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.
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.

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 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-1.
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

Maintenance
To prevent electric shock do not remove the instrument cover. There are no user serviceable parts inside. Routine maintenance
or cleaning of internal parts is not necessary. Any external cleaning should be done with a clean dry or slightly damp cloth. Avoid
the use of cleaning agents or chemicals to prevent damage plastic parts or lettering.
Entretien
Pour éviter les chocs électriques ne pas enlever le couvercle de l’instrument. Il n’y a aucune pièce reparable par l’utilisateur.
L’entretien de routine ou le nettoyage des pièces internes ne sont pas nécessaires. Tout nettoyage externe doit être fait avec un
chion sec ou légèrement humide. Éviter l’utilisation de produits de nettoyage ou des produits chimiques pour éviter d’eacer
les lettres ou d’abimer les pièces en plastique.
