SAFETY LEVELS (Seals)
CIRWATT has the necessary seals
to ensure that the meter is not tampered
with. Once the meter is installed, these
seals must always be attached.
⇒
Terminal cover seals.
These seals are attached once the
equipment has been installed. These seals
prevent the modification of the meter
connection.

The units and resolution of the energy values are the same as for the meter overflow
values, i.e. the recorder values. The units will be kWh or kVArh.
The size of the recordings will be as shown below:
Type 1 (Class 0.2S)
9 whole digits
(999,999,999)
Type 2 (Class 0.5S)
8 whole digits
(99,999,999)
Type 3 (Class 1)
7 whole digits
(9,999,999)
For Type 1 measuring equipment, the display screen only has 8 digits, in this case it
will act as follows:
Overflow (Recorder)
9 whole digits
Unit kWh or kVArh (999,999,999)
Display (Screen)
6 whole digits and 2 decimals
Unit MWh or MVArh (999,999.99)
