Push the <ZERO> button again:
Fine adjustment
within 0...3 s: the zero adjustment value changes
by one unit
Change of direction
within 3...5 s: the zero adjustment changes its
direction (the flashing frequency of
the <RUN> LED changes briefly)
If the <ZERO> button is released for more than 5 s, the
gauge returns to the measurement mode.
The zero with Base-Pressure-Offset can also be ad-
justed via the RS232C interface ( → [4]).
The <RUN> LED flashes if the signal output is negative.
4.3 Switching Functions
(CDG025D-S only)
The two switching functions can be adjusted to any pressure
within the whole measurement range (
→ 13).
The current setpoint setting
• is output at the D-Sub connector instead of the measurement
signal ( → 18) and can be measured with a voltmeter after
the <SP> button is pressed, or
• can be read/written via the RS232C interface.
If the pressure is lower than the setpoint, the corresponding LED
is lit (<1> or <2>) and the corresponding relay (
→ 18) is
energized.
