15.13.1 In-Service test mode
The In-Service Test (IST) mode is accessible by selecting the B button from
the service menu. The user can then select the B button to enable the IST
mode. In IST mode the meter registers are displayed with 4 digits to the left
and 3 digits to the right of the decimal point. This mode allows for
calibration of the meter using less energy than would be possible using the
normal display resolution. The IST mode is active for 4 hours.
Therefore, if
enabled, IST will remain in force for 4 hours, even though the service menu
will be exited after 5 minutes of no user interaction. Should the meter be
power cycled during the 4 hour period that IST is in operation, then on
power up, the meter will 'remember' that IST was in operation at the point of
power down, so will reinstate
it.
However, the 4 hour IST timeout duration
will begin from the point of power up, not from the point when it was
originally enabled.
If the user chooses not to enter IST mode, then the A button should be
selected.
The user can exit IST mode by selecting the B button from the service
menu followed by the A button.
