Real Time Clock Data Error on a TDC Ultra
A Real Time Clock error occurs in a TDC Ultra if there is an interruption in power or if a surge of power occurs. When a real time clock error occurs, the
date & time stored in the unit reverts to a default setting.
There are two potential causes of a real time clock error:
1. The internal lithium battery for the unit fails.
While the Ultra is turned on, it is powered by four AA batteries. When the unit is turned off, an internal lithium battery maintains power for the real time
clock. This lithium battery can last from 5 to 10 years, depending on how often the units are used. (If the units are turned on and used often, the battery
will last longer. If the units are left off for extended periods of time, the battery will not last as long.) If this internal battery fails, there is no power to retain
the date & time when the unit is turned off.
An easy way to test for this problem is to set the time & date in the unit then turn it off for 1-2 minutes. If the real time clock error occurs when the unit is
turned back on, it is an indication that the lithium battery is not providing power and needs to be replaced. In this case, the unit should be sent to JAMAR
for service. If the error does not occur, there is most likely not a problem with the lithium battery.
2. A static charge or other electrical charge.
Like other electronic devices, the TDC Ultra can be adversely affected by a static electric charge. This problem becomes more prevalent in the cold, dry
months of winter. Before handling the units, always be sure to properly ground yourself so that there is not a static discharge that can harm the unit.
Resetting the clock
If a real time clock error occurs, the date and time in the unit should be reset before additional data is collected. To do this, press the TAB key until
Utilities is flashing on the main menu then press DO. Next, tab until Time/Date is flashing then press DO. The TAB key is used to scroll between hour,
minute, month, day and year. The Change keys (14 & 15) are used to adjust the values. Press DO to set the date and time once it has been entered.
