A group of parameters for setting the intensity and on time of the display.
The value of this parameter in seconds determines how long the display will
show the current measured value while cycling through all set measurement
channels. During the cycling, the total leaked volumes on the flow or rainfall
channels are automatically included among the current measured values.
After pressing the PRESS button, the display is switched on, including its ba-
cklight. As the backlight is energy intensive, the switch-on time and the intensity
of the backlight can be adjusted. The backlighting time can be shorter than the
display switch-on time, which is determined by the number of displayed mea-
surement channels and the change period (see previous parameter).
Similar parameter for setting the intensity of the signal LEDs. A lower percen-
tage value of the parameter extends the life of the power supply battery. A zero
value of the parameter switches off the signalling completely.
In normal mode, the MEASURE signal LED is lit for the measurement period at
the interval specified by the Basic Archiving Interval. The measurement time de-
pends on the number of measured channels and the type of probes and sensors
connected to the analog inputs AV1, AV2 and to the RS485 serial interface. As a
rough guide, a measurement time of 0.5 sec. can be assumed for one measure-
ment channel. Signaling LEDs PV1 to PV3 indicate pulses on these pulse inputs.
This option determines whether the temperature and humidity inside the in-
strument, or the operating hours of the instrument when switched on, and the
length of time that a connected sensor error has been detected appear on the
instrument's home screen when the PRESS knob is pressed. The displayed data
is in days and hours. The display of the total on time and the time the measure-
ment was incorrect is particularly important when measuring flow for billing
purposes.
POWER
Parameters that affect the total current consumption of the Hydro Logger H1
and consequently the operating time from the power battery include, besides
the setting of the measurement frequency (see the previous parameter "Basic
archiving interval"), the time for switching on the power supply of the AV inputs
in advance of the actual measurement and especially the frequency of data ses-
sions to the server or the number of SMS messages sent.
In the idle state between measurements, the Hydro Logger H1 operates in a so-
called power saving mode in which all the instrument's circuits are switched off
except for the pulse counters and the binary input monitoring circuits. In power
saving mode, the power draw from the battery is less than 30 uA (if no OPTO
sensor powered from the Uopto terminal is connected to the instrument).
By checking this option, the 3.6V battery voltage will permanently appear on
the Uopto terminals (terminals 15 and 18 on the Hydro Logger H1 connection
board), which are used to power the OPTO sensors for the water meters. The
maximum continuous draw of a single OPTO sensor should not exceed 0.1 mA
to avoid a significant reduction in the operating time of a battery-only instru-
ment.
