Press
→ key twice
Set flow characteristics, select with
↑ or ↓ keys
• STEADY (steady flow)
• PULSATING (pulsating flow, e,g, caused by reciprocating pumps,
refer to Sections 6.5 to 6.10 ”Special applications”)
Press
↵ key to change to subfunction ”ADC GAIN”.
Set ADC GAIN, select with
↑ or ↓ keys
• AUTO (for homogeneous process liquids, low pulsation)
• 10 (for high solids contents or extremely pulsating flows)
• 30 (for solids contents or pulsating flows)
• 100 (high resolution even at low flows)
Press
↵ key three times to return to Fct. APPLICAT.
Do not change the settings of subfunctions ”SPEC. FILT.”, ”LIMIT VAL.” and ”LIMIT CNT.” as
these functions are needed to obtain steady signals for display and outputs for special
applications, see Section 6.6.

press ↵ key to change to ”Selfcheck”
Carry out selfcheck during measurement? Press
→ key
• NO • YES Select with ↑ or ↓ keys, press ↵ key to change to ”Field current”.
What is checked?
ADC gain and other parameters are continuously checked for their
permissible values and deviations.
Errors are only displayed when ”YES” is selected in Fct. 1.04 DISPLAY, subfunction ”DISP.
MSG.”. After acknowledging/deleting the errors in the ERROR/QUIT menu (see Section 4.6), the
tests described in a) and b) above are re-started. Test duration 4 to 20 minutes.
