LOG DX / TDM 200
66
The largest measurement value per measuring channel is specified by Max value.
The smallest measurement value per measuring channel is specified by Min value.
The total flow quantity of the previous night* is specified by Sum (only applies to flow
measurements).
At the bottom of the display are the start and end of the observed period.
After closing the night value display, you will find this data record as a new entry under
Data. It can be accessed and displayed there at any time.
INFO
This function is primarily useful for flow measurements.
Advantage compared to the complete measurement data selection: Small data packet,
fast data transfer, low load on the battery of the logger/device.
The 24-hour period from 6 am of the previous day to 6 am today is considered. If this
period has not yet been completed, the previous, completed 24-hour period is
considered.
7.7 Reading out an event list
To read out the event list from the logger/device, proceed as follows:
► In the start screen, tap LOG DX / TDM 200.
► Select the desired device from the Devices list.
► Tap Event list.
The connection to the device is established. The event data is received by the
PocketServer and displayed on the screen.
7.8 Real-time measurements
You can perform a real-time measurement with the logger/device. The measured values
are displayed ‘live’ on the screen.
NOTE
The real-time measurement requires a great deal of energy and considerably reduces
the battery life of the logger/device. Only use the real-time measurement for as long as
necessary.
► In the start screen, tap LOG DX / TDM 200.
► Select the desired device data from the Devices list.
► Tap Realtime.
The connection to the device is established. The device starts to measure. The recorded
values are received in real time by the PocketServer and displayed in a diagram. Up to
four curves can be seen. Each curve represents a measurement channel of the device.
► Tap the Stop button in the top left to stop the current measurement.
The device stops recording and transmitting data to the PocketServer. The diagram
view freezes. A dialogue window opens. Decide here whether you want to save the data
from this measurement to the PocketServer.
