15 Setting date and time
The internal clock of the OTT ecoLog 500 (3G) is a high-accuracy realtime-clock.
It runs as soon as batteries are installed in the OTT ecoLog 500 (3G). After the
batteries are removed, the clock will continue to run for approximately 10 min-
utes. After a longer period of power loss, the OTT ecoLog 500 (3G) will lose the
date and time. When batteries are reinstalled, the OTT ecoLog 500 (3G) adopts
the date and time of the last stored measured value, with one minute added to the
stored time. The date and time are set using the operating program.
How to set the date and time
Start the operating program.
Establish the PC/OTT ecoLog 500 (3G) communication link, refer to Chapters
9.2 or 9.3.
Click the "Setup device" button in the start window.
Select the "Date/time" function in the "OTT ecoLog 500 (3G)" menu
➝
The
operating program reads the date and time from the OTT ecoLog 500 (3G)
and opens the "OTT ecoLog 500 (3G) – date/time" window.
If necessary: click the "Refresh" button
➝
The OTT ecoLog 500 (3G) reads the
date and time again.
If necessary: Adjust the desired values in the two input fields.
Click the "Set date/time" button
➝
The operating program sets the
OTT ecoLog 500 (3G) date and time to the PC time/date or to the values set.
Click the "Exit" button.
Please note:
If the PC is in Daylight Saving Time (ID: PC (DST)), the operating
program automatically uses the standard time without DST correction. To obtain
continuous time series, it is a good idea not to use Daylight Saving Time in the
OTT ecoLog 500 (3G).
In connection with a GPRS(/3G) remote data transfer and the "Time synchro -
nization" function, it is necessary to reference the time to UTC/GMT and to set the
time zone of the station in the "Advanced operation", "OTT ecoLog 500 (3G)"
window, refer to online help.
Note
When the unit is put back into service, it may be appropriate to erase the data
memory after having set date and time, refer to Chapter 16.
