In this example of an Excel graph, you can see that the AIR TEMPERATURE LIMIT and REMOTE LIMIT
were set at 120°F, the SURFACE TEMPERATURE LIMIT was set at 95°F, and the MOISTURE 1 LIMIT and
MOISTURE 2 LIMIT were set at 15%. The RH or Relative humidity stayed around 15 to 20%. The INTERNAL
TEMPERATURE stayed around 80-90°F. The E-TES unit never had the AIR FLOW turn off or an
OVERTEMP condition.
The AIR TEMPERATURE PROBE reading exceeded the limit twice and turned the heater off for two short
periods. When the air temperature cooled the heater turned back on both times.
The moisture content of the wood started over 60%. The MOISTURE 1 VALUE and MOISTURE 2 VALUE
both dropped but stayed above the 15% limit and did not shut the heater off.
You can modify the graph to chart the readings which you decide are the most relevant to each job. For this chart:
the following changes were made in the graph:
•
The REMOTE ON was not charted.
•
The INTERNAL LIMIT was not charted.
