INTERNAL ELECTRICAL SCHEMATICS

SELECTION OF DISPLAY MULTIPLIER

  • The last digit/letter represents the selection code : Blinking red LED indicates negative pressure.

  • Diagonal column: Display multiplier cannot be selected due to resolution and number of digits.
  • (Selection code is not indicated either.) Selection code is set at “A” prior to shipment.

ANALOG OUTPUT MODE

Selection code is set at “G” prior to shipment.

SWITCH OUTPUT MODE

  • Note 1. In the Separate Mode, setting 1 corresponds to SW1, and Setting 2 corresponds to SW2.
  • Note 2. In the Window Comparator Mode, the minimum value for SW1 and SW2 corresponds to Setting 1 and the maximum value corresponds to Setting 2.
