Clock Function

Reference
Numeral Memory Tables Used with the Clock Function
456
The NT31/NT31C has a clock function for setting and displaying the date and time.
The clock function is backed up by the built-in battery of the NT31/NT31C.
- When the battery voltage becomes low, the time data cannot be retained by
turning off the power to the NT31/NT31C, or resetting the NT31/NT31C, conse-
quently the clock function will not operate correctly.
- The NT31/NT31C does not allow display and setting of clock data with the clock
function from the Support Tool. To set the time, use System Menu or numeral
memory table operations.
- No calendar or time data is set on shipment from the factory.
The NT31/NT31C uses numeral memory tables No. 247 to 255 for clock data.
As shown in the table below, numbers 247 to 253 are for display and reading only,
and numbers 254 and 255 are for time setting.
Numbers 247 through 253 store clock data which is updated by the internal clock
of the NT31/NT31C. This data cannot be rewritten by the host.
