Averaging
Moving average values for every five measured values and the maximum value (MAX) and
minimum value (MIN) of the moving average values are displayed on the screen.
0% and 100% Values
By mapping the output value (specified according to the specifications of the device to be
calibrated) to the 0% or 100% source value of this instrument, you can determine the output value
of the device to be calibrated for the source value.
For example, if the source value of 0% is 1 V and that of 100% is 5 V and the output values are
4 mA and 20 mA when 1 V and 5 V are input to the device be calibrated, assign 4 mA to the
measured value of 0% and 20 mA to that of 100%.
In this situation, the output value (specified according to the specifications of the device to be
calibrated) is 8 mA for a source value of 2 V of this instrument.
4 mA + (20 mA - 4 mA)×(2 V - 1 V)/(5 V - 1 V) = 8 mA
The CA550 calculates the error in the actual output value relative to the output value (specified
according to the specifications of the device to be calibrated) that is mapped to the source value.
Furthermore, this instrument calculates the measurement value percentages relative to the
specified 0% value and 100% value.
