Pressing the “ ” key advances to the Energy Rate edit mode. Pressing “ ” and “ ” scrolls the
count in minutes from 1 to 60 and from 60 to 1, respectively. Ex. If Energy Rate is set to 2 then energy
will get stored after 2 minutes on the modbus.
Pressing “ ” key sets the value selected and advances to the “Energy Rate” menu (see Section
3.2.1.13).
NOTE: Default value is set to ‘15’ i.e. 15 min.
3.2.1.14 Impulse Rate
This screen shows user to Impulse rate depending upon the PT
secondary and CT Secondary set by user.
‘k’ indicates value is multiplied by 1000.
Pressing the “ ” key advances to “Version Information” screen (see
Section 3.2.1.15). Similarly, pressing the “ ” key advances to
“Energy Rate” screen (see Section 3.2.1.13).

3.2.1.15 Version Number
This screen shows user the current firmware version implemented in
the instrument and the selected system type.
e.g. The image here displays that the firmware version is 1.01 and
the instrument is currently in three phase four wire.
Pressing the “ ” key advances to “quit” screen (see Section
3.2.1.16). Similarly, pressing the “ ” key advances to “Impulse
Rate” screen (see Section 3.2.1.14).
1. For per phase / 1P2W System Energy,
Nominal Power = PT Sec (LL) * CT Sec / 1.732
2. For Three Phase System Energy,
Nominal Power = 3 * PT Sec (LL) * CT Sec /
1.732
*Note :
Impulse Constant of 16000 and 32000 are
applicable for 1P2W System and per phase energy
of Three Phase System.
