Settings Of Calculation Channels - Metronic DL7 Series User Manual

13 SETTINGS OF CALCULATION CHANNELS 
In order to set the calculation channel, choose from the side menu the button
, and then the channels icon
computed and enter the formula which the value will be calculated.
The device allows to perform selected mathematical operations: addition, subtraction,
division, multiplication, raising to the power of 2 and 3 and the square root. The formula
entered can contain up to 200 characters.
! The device performs calculations according to the order of operations
(operations in brackets, exponentiation / extraction of a root, division /
multiplication, addition / subtraction).
The value of another channel may be used in calculation. In this case, the channel
number should be preceded by # sign.
For example:
 formula
In calculation of square root, the value is calculated of only first character after the
√ mark. If the square root has to be calculated from the value of several channels,
calculated value should be placed in brackets.
For example:
 formula
 formula
 formula
 formula
Similarly, in the case of exponentiation (the possibility of choosing the second and the
third power), the value is calculated of only the first character entered before the
mark. If the value from several channels is raised to power 2 or 3, the calculated value
should be put in brackets.
For example:
 formula
 formula
 formula
 formula
#1+#2 adds the values of the first and second channels.
√123
calculates the square root of 123,
√#1
calculates the square root of the value of channel 1,
√#1+#2
calculates the square root of channel 1 and to the
result adds the value of channel 2
√(#1+#2)
calculates the square root of the sum of values
channels 1 and 2.
2
123 raises the value of 123 to power 2,
2
#1 raises the value of channel 1 to the power of 2,
2
#1+#2 raises the value of channel 2 to the power of 2 and to
the result adds the value of channel 1,
2
(#1+#2) raises to the power of 2 the value from the sum of
values of channels 1 and 2.
