Control Chassis
Once every year, ensure that the fan mounted to chassis rear panel is
functioning properly. Once every two years, run Windows disk defragmenter
“Analyze” and follow Windows Recommendations. You can run the defrag
analysis and defragmenter from the master station computer running APP
ClearView (Maintenance).
Note:
If the system is using a solid-state drive, defragmentation does not
need to be done.

Calibrate analog channels once every 5 years. See calibrating DC offest and
calibrating Slope
9.3 Recommended Setup for MW Channels
(Using 4ma-20ma Transducer)
To Complete the Recommended Setup for MW Channels
1.
Calculate the CT/PT value.
For example, suppose the resistor used with the transducer is 143 ohms and the transducer full
scale is 550MW @ 20ma. In this case, the calculation would be as follows:
4ma (143 ohms) = 0.572V, which needs to equal 0MW
20ma (143 ohms) = 2.860V, which needs to equal 550MW
2.860V – 0.572V = 2.288V
550MW/2.288V = 240.3846 which is the CT/PT that needs to be used in order to display proper
primary values.
2.
In the Point Assignment Record for this analog channel, enter w(Mwatt) for the Channel Type.
Then enter 240.384 for the CT/PT value, and enter 5 for the Full Scale value (on the secondary
1MW-1V). Click
Save
in the
Point Assignment
window.
3.
In the APP Recorder, open the OScope (
File
menu,
Show OScope
). View the analog channel that
is being setup for MW.
4.
With no signals attached to this MW channel, un-calibrate the offset and the slope.
5.
Apply a 0.572VDC signal (representing 4ma, 0MW) and calibrate the offset.
6.
Apply a 2.86VDC signal. You should read a primary value of 550MW for this MW channel.
