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.
