4. Setting up unit - SET UP

If the whole measurement used does not need to be seen the lower value of
Zoom start the required range can be entered here (increased resolution).
Example: Transmitter with 0-14 pH, required range 5-9 pH. Set up a "5".
The same as "Zoom start". Enter the upper value of the required range.
Zoom end
Example: Transmitter range required is 5-9 pH. Set up a "9".
The more unwanted interference on the measurement signal the higher the
Damping/filter value to be entered here. Result: fast changes are dampened/suppressed
(for experts: "lowpass 1")).
Offset Factory default "0". Preset value is added to the measured input signal.
Copies all settings of the actual channel to the selected channel (incl. Alarm
set points). Saves time, when similar channels are connected to different
inputs (e.g. pressure sensors before and after filters).
Copy settings
Hint: The measurement point identifier is also copied to the target channel.
The last characters are however substituted by the channel number (e.g. "02",
"03", ...).
Only on direct connection to thermocouples.
"Intern": Compensation of the voltage error occurring at the terminals due to
measurement of the rear panel temperature.

Comparison point
controlled external comparison point. Recommendation when using
(cold junction)
thermocouples type B (Pt30Rh-Pt6Rh): When connecting this thermocouple
directly then set it up without an external comparison point "Extern (0°C)". The
reason: there is a non-linear curve in this thermocouple at the range
of 50°C.
By integrating the analogue signal (e.g. flow rate in m³/h) quantities (in m³) can

be calculated.
Select the required time base. Example: ml/s -> time base seconds (s); m³/h

-> time base hours (h).

• Integration (option): Setting only
required if the analogue measurement
point is being integrated, e.g. for
quantity measurements. Daily and
total values can be calculated.
• Alarm set points: Setting up is only
required if alarm set points are to be
monitored on this channel.
