Internal Clock
Part 17997 Rev. 6, March 2011 2-19
2.8 INTERNAL CLOCK
An internal real-time clock (RTC) circuit provides a calendar and a permanent clock, unless
the battery is disconnected. The clock uses a crystal oscillator as its time base; its 0.01 %
accuracy (four minutes per month) is independent of the ac power supply frequency.
Note: The calendar accounts automatically for leap years (366 days). However, it does not
include daylight saving functions.
The Hydran 201T i ’s internal clock allows to manage the following features:
• Historic data files (see Section 4.5.1 on page 4-12)
• Delays of all alarm conditions (see Chapter 10)
• Semimonthly, automatic sensor tests (see Section 4.5.4.2 on page 4-19)
The H201T i ’s date and time are set in the Date&Time submenu (see Section 4.5.5 on
page 4-21).
Do not dissemble, crush, puncture or incinerate the battery. Handle a
damaged or leaking battery with extreme care. If you touch the
electrolyte, wash the exposed skin with soap and water. If the
electrolyte contacts your eye, flush the eye with water for 15 minutes.
If you have inhaled the electrolyte, move to fresh air, and monitor
breathing and circulation. In each case, seek immediate medical
attention. When discarding a battery, follow applicable safety
procedures or contact your local waste disposal provider regarding
local restrictions on the disposal or recycling of batteries.
