pendently specified for each input channel (see Section 5.2.1). Some conver-
sions, namely those for thermocouples, may use the CJC temperature read from
the module with the measurement. Converted measurements are immediately
passed to the unit conversion block.
Unit Conversion
The unit conversion block converts measurements to the appropriate units (see
Section 5.5.1). The temperature conversion block produces temperature values
in degrees Celsius (C). If the system units are degrees Fahrenheit (F) or Kelvin
(K), the temperature value is converted accordingly.
Primary Measurement Display
Each new measurement is immediately displayed on the front panel screen in
the primary measurement window. The channel number appears on the right.
Graph and Scroll Windows
Each new measurement also appears in the graph or scroll window, if visible.
Memory
Each new measurement is stored in memory. Up to 1000 measurements can be
stored. (The storage capacity may be reduced if a large number of input chan-
nels are added.) If the memory is full, the earliest measurement in memory is
discarded when a new measurement is stored. The channel number, time, and
units are stored with the measurement value. Measurements stored in memory
can be printed (see Section 5.3.4).
Printer Outputs
Each new measurement will be printed to any enabled printer device (see Sec-
tion 5.3.3). The channel number, units, time, and date are also printed.
Statistics
Each measurement is processed by the statistics block. The statistics block pro-
duces the following: the measurement value (no calculation), average, standard de-
viation, maximum, minimum, and spread. Each input channel is processed
independently. The most recent statistical results for each input channel are stored
internally for later transfer to outputs. The statistical registers can be reset by the
user (see Section 5.3.5).
Output Routing
The output routing block feeds measurements to the appropriate output chan-
nels. Any output channel can receive measurements from any input channel as
well as the results of statistical calculations (see Section 5.3.2). When a new
measurement is available, the output routing block passes it to all display fields
and output channels programmed to receive it.
