LOG D-3 / SebaFlow / TDM 300

 Interval

Select the measurement interval

Channel 1 to Channel 4 drop-down menus

You can find the measurement-channel specific settings here:

 Channel active

Activate/deactivate the measurement channel for the measurement.

A deactivated channel does not participate in the measurement. All sensor settings

are then hidden.

 Sensor

Select the connected sensor type from the list. Most other parameters are inserted

automatically

If the correct type is not in the list, select User defined.

 Type

Select the type of input signal from the list (voltage, pulse, etc.)

 Unit

Select the measuring unit for the measurements.

 Conversion

Provide information on converting signal input values in output measurements.

Example pressure measurement: 5 V at the sensor equals 10 bar in the display (or

similar)

 Pressure shocks

Should pressure fluctuations (pressure shocks) be recorded? Then activate the

checkbox active. Then, under Threshold, specify the amount of pressure change to

be a ‘pressure shock’. Activate the checkbox 10Hz sampling, if the recording should

take place with an extra high sampling rate. Caution: The high sampling rate subjects

the logger battery to an extremely high load! When the checkbox is deactivated, the

sampling rate is only 1 Hz.

 Counter

For flow measurements, you can enter the counter reading of a water meter as a

basis for comparison here.

Alarm input 1 and Alarm input 2 drop-down menus

The settings for setting up alarm loops with external alarm devices are found here:

 Trigger

Select the input voltage at which an alarm will be triggered.

5V … Alarm at >2.5 V at signal input

0V … Alarm at <2.5 V at signal input

 Destination

Select the alarm destination.

For detailed explanations of the individual settings, refer to the operating instructions of

the logger/device.
