17. GENERAL
17.1 If the symbol (
)appears, this means that the test resistor is too hot and the
automatic cut out circuits have operated. Allow the instrument to cool down before
proceeding. The overheat circuits protect the test resistor against heat damage.
17.2 The test button may be turned clockwise to lock it down. In this auto mode, when using
distribution board lead Model7188, tests are conducted by simply disconnecting and
reconnecting the red phase prod of the Model7188 avoiding the need to physically
press the test button i.e. 'hands free'.
17.3 When the display shows the low battery indication, (
), disconnect the test leads from
the instrument. Remove the battery cover and the batteries.
