Basic Key Operations
For setting up in each setting mode, the contents of selection UP/DOWN keys are chosen, respec-
tively. In all setting modes, values are set with the UP/DOWN keys. Use UP key to increase and
DOWN key to decrease values. A repeat state occurs in three phases of speed when the UP or
DOWN keys are pressed for more than 0.5seconds to increase or decrease numerical value.
Adjusting Zero Point
In Measurement Mode, press the MODE and DOWN keys for greater than 3 seconds; this will dis-
play "_ _ _" after releasing pressure from the pressure port. Approximately 1 second later an auto-
matic zero adjustment takes place and the pressure displays as zero.
When the zero adjustment is successful

10% F.S. , zero adjustment does not happen.
Peak/Bottom (Max./Min.) Hold Display Mode
The GC35 unit keeps the maximum and minimum pressure level applied to the pressure port as
peak and bottom values respectively, in the internal memory. The peak and bottom values are dis-
