Fig 5.7.2 – System Setup
5.7.1 Temperature Compensation
This is the Ambient Temperature Compensation adjust and is used to compensate for
adverse environments when using thermocouples. This feature is entered from the system
admin menu by pressing the icon shown right.
At the terminal blocks where the thermocouples connect to the recorder there is a new thermocouple junction
introduced which can affect the reading. There is a sensor there measuring the ambient temperature at the
terminals and is used to compensate for any offset that may result. In certain circumstances the ambient
temperature may not be able to adequately compensate for external temperatures resulting in an error in the
readings.
Selecting this option from the menu will pop up the Ambient Temp
Compensation box shown right. This box can be moved by tapping and
holding the blue bar while dragging the window. The user can view the
live thermocouple data while adjusting the compensation and can see
the actual compensation value in the box below the Deg-F checkbox.
Use the Offset dropdown box to adjust the reading by up to +3 degrees
in 0.5° increments in either Centigrade if the Deg. F checkbox is unchecked or Fahrenheit if the Deg. F
checkbox is checked.
Update button - make the adjustment.
Done button - exits the window.
5.7.2 System Setup
The System Setup allows the administrator to adjust some basic settings of the unit like Unit Tag.
This feature is entered from the system admin menu by pressing the icon shown right. This will
bring up the System Setup dialog box.
The options are as follows:
5.7.2.1 NTP Time Server
NTP is Network Time Protocol. The Recorder has
the ability to go out over the internet and get a
time update from one of several NTP time servers
if the Time Server Checkbox is checked.
Note that you DO NOT NEED to use this unless
you want to synchronize a number of units spread
about on different networks. The unit will connect
and synchronize to any network server it finds on
the Ethernet at startup time.
There needs to be a valid IP address for NTP to
work in the IP entry box. A list of NIST Internet
Time Servers can be found at (among others)
http://tf.nist.gov/service/time-servers.html . If the
Time Server Enable box is checked the unit will synchronize its time at startup and every 12 hours
thereafter. Note: The NTP setting is only recognized at start up. It is necessary to Save the
Configuration and restart the unit (you can, with caution use the reset button.)
