Display (LCD)
The device is equipped with 8-digits LCD (Liquid Crystal Display) with special symbols to display
parameters, measurement units and operation modes
The following information can be displayed: integral and instantaneous measured parameters, and archive
data, and device configuration information listed in p.6.3.
Display resolution of energy:
00000001 kWh, 00000,001 MWh (Gcal or GJ)
Display resolution of volume:

Data registration and storage
Every hour, day and month values of the measured parameters are stored in memory of the meter
All data from archive can be read only by means of the remote reading (see p.6.5)
In addition data logger records of monthly parameters can be seen on the display (see p. 6.3.1)
Following hourly, daily and monthly parameter values are recorded in heat meter memory:
