In order for operator to be familiar enough with performing measurements in general and their typical applications it is advisable to read TESTBOY handbook Guide for testing and verification of low voltage installations. The instrument is equipped with the entire necessary accessory for comfortable testing. -
Page 7: Safety And Operational Considerations
2.1 Warnings and notes In order to maintain the highest level of operator safety while carrying out various tests and measurements, TESTBOY recommends keeping your TESTBOY instruments in good condition and undamaged. When using the instrument, consider the following general warnings: symbol on the instrument means »Read the Instruction manual... - Page 8 Insulation resistance, continuity functions and earth resistance measurements (TESTBOY TV 450 (TYPE B)) can only be performed on de-energized objects. PASS / FAIL indication is enabled when limit is set. Apply appropriate limit value for evaluation of measurement results.
- Page 9 TESTBOY TV 450 Warnings and notes Continuity functions If voltages of higher than 10 V (AC or DC) is detected between test terminals, the continuity resistance test will not be performed. Before performing a continuity measurement, where necessary, compensate test lead resistance.

Page 10: Battery And Charging
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 above. Do not recharge alkaline battery cells! -
Page 11: New Battery Cells Or Cells Unused For A Longer Period
Ni-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 Completely charge the battery. -
