2.6. Display Mode
The meter displays
numeric data.
Display mode LCD display of wide-temperature range
Character digits for data item display 8 digits including 6 integers and 2 decimals
Character digits for data ID display 3 digits
2.7. Pulse Constant
Active pulse constant 400 imp/kWh
Reactive pulse constant 400 imp/kvarh
2.8. Active Check Output
The meter is equipped with special pulse indicator for testing active energy (LED is on the
nameplate of meter). In order to ensure the accuracy of active measuring test, according to
different current test points, pulse quantity collected from test should be incremented with the
increase of current, and reasonably select pulses between the numbers 1~8.
