5 Operation / adjusting device settings - Set-up to commissioning Memo-Graph S

32 Endress+Hauser

Signal settings -> Analogue inputs -> Analogue input x: Integration sub-menu:

Settings only required if this analogue measuring point is to be integrated - e.g. for quantity calcu-

lation. Analysis times can be set under “Signal analysis” (see Chapter 5.7.3).

Zoom end Same as “Zoom start”. However, enter the upper value of the required section here.

Example:

Transmitter 5-9 pH. Enter “9” here.

Offset Factory setting “0”.

Set value is added for further use (display, storage, limit value monitoring) for real measured input signal.

Interference suppression (dam-

ping / filter)

The more undesired interferences superposed on the measuring signal, the higher this value should be set. Result: quick

interference surges are attenuated / suppressed (for experts: “1st order low-pass filter”).

Hot pin calibration Position only available for direct connection of thermal elements.

“Internal”: compensation of error voltages occurring at the connection terminals by measuring the back wall tempera-

ture.

“External x °C/°F”: compensation of error voltages by using thermostatic external cold junctions.

Recommendation when using type B thermal elements (Pt30Rh-Pt6Rh):

Always set “External (0 °C / 32 °F)”, even when using direct connection without external cold junction.

Reason: unlinear characteristic curve of this thermal element in the range of < 50 °C / < 122 °F.

Copy settings Copies the settings of the current channel into the selected channel (including limit values). Both of the last positions of

the target channel's designation are replaced with its channel number.

Set-up -> Signal settings -> Analogue inputs -> Analogue input x

Set-up -> Signal settings -> Analogue inputs -> Analogue input x -> Integration

Integration basis The quantity (here in m3) can be calculated from an analogue signal (e.g. flow in m3/h) using integration. Here, select

the corresponding time basis.

Examples:

l/s -> time basis in seconds (s);

m3/h -> time basis in hours (h).

Unit integrated Here, enter the unit of the quantity determined using integration (e.g. “m3”).

Display alternately Selection of whether and which counter is to be displayed alternately with the current value. The analogue value is then

shown for approx. 6 s, the meter reading for approx. 4s alternately.
