10 Basic Maintenance W arning T o avoid shock, remove the test leads an d any input signals before opening the case o r replacing the battery or fuses. Opening the Meter Ca se Caution T o avoid unintentional shock circuit, always place the uncovered Meter assembl y on a protective surface. When the ca se of the Meter is open, circuit connections ar[...]

11 T esting Fuses T o test the internal fuses of the meter . 1. T urn the rotary selector s witch to the Ω position. 2. T o test FS1, plug a test lead into V Ω Hz input terminal, and touch the probe to the A input terminal. The displ ay should indicate between 0.0 to 0.2 Ω . (Bussmann KTK-10 recommended). If display reads higher than 0.2 Ω [...]

12 Performance T est s The following performance test s verify the co mplete operability of the Meter an d check the accuracy of each Meter function against the Meter’s specifications.
