ADJUSTMENT INSTRUCTION
1. Application Range
This spec sheet is applied to all of the PP11K chassis. 
2. Specification
(1) Because this is not a hot chassis, it is not necessary to use
an  isolation  transformer.  However,  the  use  of  isolation
transformer will help protect test instrument.
(2) Adjustment must be done in the correct order.
(3) The adjustment must be performed in the circumstance of
25 °C ± 5 °C of temperature and 65 % ± 10 % of relative
humidity if there is no specific designation.
(4) The  input  voltage  of  the  receiver  must  keep  100  V
~ 240 V, 50 / 60 Hz.
(5) The receiver must be operated for about 5 minutes prior to
the adjustment when module is in the circumstance of over
