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 “1” prior to shipment.
Analog output mode

- When shipped from our factory-101R : R mode is set at “1”, 102R : V mode is set at “3” and 103R : G mode is set at “2”.
- The above 3 types can be set at “1”, “2” or “3”. However, the accuracy at V mode of 103R can’t be guaranteed.
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.
