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.
