User Manual
: Changing from stop to start will stop the measurement and will maintain the last data
Note
record for the watt-hour meter. To restart the measurements, the field is toggled to the stop
position from the start position and the previous data will be reset to zeros.
WATT HR, POWER and PK CURR will display the data for the phase selected with the phase
key. If the phase is selected for all phases in a two or three phase system, the WATT HR and
POWER fields will show the sum of all phases. PK CURR will remain at the last selected phase.
Note: Changing Mode of operation from single phase to three phases while the Watt-hour meter
is in the active state will generate an error: "Input buffer full". This error will halt the
measurements. To clear the error, the Watt-hour meter must be switched to the stopped state.
It is advised that the Watt-hour meter should be set to the stop state before changing the mode
of operation.
