ii. 30 days of continuous/cumulative outage; (c) During a power outage, critical program and billing data is written to non-volatile memory. When power is restored, data is returned to active memory and data collection resumed; (d) Following a outage, register time is a maximum of 30 seconds. “catch-up” During the time the meter still calculates consumption and demand “catch-up” quantities. Optional inputs and outputs also function during this time; (e) During power outages, time is maintained with a cumulative error of no more than 2 minutes per week (0.02%); (f) The meter records the date and time of any power outage; and (g) Meters may also record the duration of any power outage. B-1: 3.6 Meter Test Mode Function Meters have the following test mode functions: (a) The meter has the capability of a Test Mode function that suspends normal metering operation during testing so that additional consumption and demand from the tests are not added to the meter’s totals; (b) The Test Mode function is activated by a permanently mounted physical device that requires removal of the meter cover to access or by a meter programmer connected to the optical port; (c) Activation of the Test Mode causes all present critical billing data to be stored in memory and restored at the time of exit from the Test Mode; (d) Upon activation of the Test Mode, register displays accumulate beginning from zero; (e) Actuation of the billing period reset device during Test Mode resets the test mode registers; (f) a programmable time-out period, the meter automatically exits from Test Mode and returns to normal metering; and (g) The default Test Mode registers for an unprogrammed meter include as a minimum: i. Time remaining in the test interval; ii. Maximum kilowatt block demand; and iii. Total kilowatt-hours. B-1: 4 DISPLAY REQUIREMENTS
