Analog recording channels can also be set up to measure flow via pulses fed
from a suitable type of water meter to inputs PV1 to PV4 of HydroLogger H1.
The following figure shows the window of channel C5 set up in this way.
Setting the analogue channel parameters is described on p. 46 in chapter 6.4
BINARY CHANNEL DISPLAY
Binary channels are used to record events that can be expressed by two states
(ON/OFF). Typically, these channels record pump operation or failure, building
entry , manhole flooding, etc.
Under the status of a binary channel, the total time of switching on (off) of this
channel can also be displayed, the so-called motor hours or operating hours.
The setting of binary channel parameters is described on page 5.60.

Switching on the internal GSM/GPRS module
A long press of the button (3 sec
) during the cyclic display of the measurement
channels causes the GSM module to switch on. If the Hydro Logger H1 manages
to log in to the network (a suitable SIM card with an unblocked PIN entry requi-
rement is installed, there is sufficient GSM signal at the antenna location and
the power battery has sufficient capacity to power the GSM module), the Hydro
Logger will be logged in the GSM network for two minutes. During this time, the
GSM field strength is repeatedly detected with a period of approximately 10 sec
and this value will be displayed on the display.
If you need to extend the display switch-on time - e.g. when searching for the
optimal location of the GSM antenna, you can press the PRESS button briefly (1
