Pressing the MODE
through appropriate displays and select feature to change/confirm. LED ring will flash until
this menu is exited to the Measurement Mode by holding the MODE
seconds. The setting mode is used to select comparator operation, pressure unit, indication
scaling, scaling of analog output and filter time constant.
Note: Editing the setting value in function setting mode recalculates all of the setting values includ-
ing the comparator. Please note that when the recalculated setting values are out of the display
range, they will be adjusted to the upper or lower limit value that can be processed internally.

For the unit equipped with two comparator output option, both comparators will be in the same
operation mode.
Filter Setting
The GC35 is equipped with 5 internal time constant filters. Use of the function is recommended
when measuring transient pressure source such that display, comparator output, analog output do
not stabilize. The selected time constant filter is reflected on comparator/analog output as well.
