CDG100-OP-LIT (2010-1)
The offset should not exceed 2% of the F.S. (+200 mV). At a
higher positive offset, the upper limit of the measurement range
is exceeded.
Zero adjustment using the ramp function can be
performed via
• the <ZERO> button on the gauge,
• the RS232C interface (→ [1]).
Recommended procedure for adjusting the offset of a
measuring system:
→ Notice 23.
Operate the gauge for at least 90 minutes under constant
ambient conditions (until the signal is stable).
Push the <ZERO> button with a pin (max. ø1.1 mm) and
keep it depressed. The <STATUS> LED starts blinking.
After 5 s, the zero adjustment value, starting at the current
output value, keeps continually changing (ramp) until the
button is released or until the setting limit (max. 25% F.S.)
is reached. The corresponding output signal is delayed by
about 1 s.
Keep the button depressed
max. ø1.1 mm
