Control channels
The Hydro Logger H1 contains 9 control channels K9 to K17 that monitor instru-
ment operating parameters such as the capacity of the power battery, tempe-
rature and humidity inside the instrument, the magnitude of the external power
supply voltage and the readings of connected sensors and probes.
The user has the option to enable/disable the selected control channel and set
a common archiving interval. Usually this interval is set to 1440 min (=1 day) in
order not to increase the volume of archived data too much.
Channel
Measured variable
K9. Ubat-low [V]
Unloaded lithium battery voltage (I=5 mA). Measurements are taken at 24 hour inter-
vals or after each data session to the server.
K10. Ubat-high [V]
Voltage of the loaded lithium battery (I=100 mA). Measurements are taken at 24 hour
intervals or at the end of each data session to the server.
K11. BatPct [%]
Capacity of the power battery calculated from the difference of Ubat-high and Ubat-low.
K12. Iopto [mA]
The amount of current drawn from the Uopto power terminals (terminals 15 and 18).
Externally powered OPTO sensors are usually connected to these terminals. Since the
power supply to the sensors is continuous, the current draw of the sensors should not
exceed 0.1mA so as not to reduce the operating time from a single power battery.
K13. Ipwr [mA]
The amount of current drawn from the Unap power terminals (terminals 3, 6 and 10).
Analog sensors with 4-20 mA output or probes communicating via RS485 serial interface
are connected to these terminals. The power supply to external sensors and probes is
only momentary for the duration of the measurement of the monitored quantities.
K14. Inter.temp [°C]
Temperature inside the device.
K15. Int. humidity [%]
Relative humidity inside the instrument. A value above 80% indicates a violation of the
instrument's tightness and may lead to damage to the electronic circuits in the long
term. An RH sensor is not standard with the instrument.
K16. Ext.temp [°C]
Temperature measured by external temperature sensor
K17. Uext [V]
External supply voltage at terminals 1 and 2. Internal lithium. The battery is automati-
cally disconnected and the power supply to the instrument switches to the external
power supply when the voltage exceeds 8 V at terminal Uext
Fixed preset control

trol channel can be
switched off or on for
