Stop bits are added to the end of each data byte transferred over serial communication to allow a
pause between two bytes. One or two bits may be used. The default setting on most Modbus RTU
devices is one stop bit, but some dataloggers may require that the instrument is configured to use
two stop bits.
5.1.5 4-20 mA PARAMETERS
Figure 5-5: 4-20 mA Parameters
4-20 mA min: To configure the 4-20 mA output range, the minimum measured value which will
correspond to 4 mA analog output needs to be set. The value is set in the currently
configured measurement unit.
Example: If measured values are expected to fall within the range of 700 mm to 5000 mm,
it is recommended to configure the minimum value to slightly below 700 mm (for example
500 mm). Alternatively, if the resolution is not critical, then the minimum value for 4-20 mA
output can be left to the instrument minimum of 0 mm.
4-20 mA max: To configure the 4-20 mA output range, the maximum measured value which will
correspond to 20 mA analog output needs to be set. The value is set in the currently
configured measurement unit.
Example: If measured values are expected to fall within the range of 700 mm to 5000 mm,
it is recommended to configure the maximum value to slightly above 5000 mm (for example
6000 mm). Alternatively, if the resolution is not critical, then maximum value for 4-20 mA
output can be left to the instrument maximum.
5.2 PROCESSING PARAMETERS
5.2.1 FILTER TYPE
Changes the type of filter which is used to smooth the measured data.
Note that not all firmware versions support all the Filter Types. Firmware versions and what they
support are listed at then end of this section.
No Filter: - No filtering is used and the raw measurements are reported.
