Section 5 – Recorder Setup
5.7.1Temperature 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
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.
5.7.2System 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:
5.7.2.1NTP 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)
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.)
