Metrel d.d. TV 465 General description 1 General description The multifunctional portable appliance tester TV 465 is intended to perform measurements for testing the electrical safety of portable electrical equipment. The following tests can be performed: earth continuity resistance;...
Do not use the instrument and accessories if any damage is noticed! Appliances MUST be fully disconnected from the mains supply before it is connected to the TV 465 in order to perform a PAT test. Do not touch any test leads/terminals while the appliance is connected to the TV 465.
If the instrument is not to be used for a long period of time, remove all batteries from the battery compartment. Alkaline or rechargeable Ni-Cd or Ni-MH batteries (size AA) can be used. Testboy recommends only using rechargeable batteries with a capacity of 2100mAh or higher.
Cd cells can be subjected to these chemical effects (sometimes called the memory effect). As a result the instrument operation time can be significantly reduced during the initial charging/discharging cycles of the batteries. In this situation, Testboy recommend the following procedure to improve the battery lifetime: Procedure Notes ...

PAT tester should be verified at regular intervals and recorded. This is of special importance if the PAT tester is used on a daily basis. The TV 465 includes an in- built Calibration Unit (‘Checkbox’) that is independent from the other instrument’s electronic circuitry and connected directly to the output terminals of the instrument.
