5 Set the Unit you want to use for calculation using maximum 6 alphanumericals or
the symbols #, %, &, ( ), *, +, -, ., and /.
6 Alarm settings and printing-related DR settings, are equal to those made for
measurement channels.
Computation equation
In addition to operators in the Operators Selection dialog box the following symbols can
be used in equations:
(/) : Used for ( ) setting.
K :
Used if equations contain constants K01 to K60.
M : Used to specify the measurement channel No. for which the data saved on the
RAM disk is to be re-generated. Applicable for the DR232-1/DR242-1 equipped
with a floppydisk drive.
A : Used to specify the computation channel No. for which the data saved on the
RAM disk is to be re-generated. Applicable for the DR232-1/DR242-1 equipped
with a floppydisk drive.
C : Used to specify communication input data (digital data).
G : Used to specify the group No. for which CLOG (computation of data of a group
measured on the same time) is to be used.
Restrictions in equations
• The specified computation equation for a computation channel No. can contain
only computation channel Nos. as variable which are equal to or smaller than set
computation channel No.
(Example) A02=001+A01
In this example, any computation channel No. which is equal to or greater than A03
cannot be used.
• Either TLOG or CLOG can be used in an equation.
Note
• Each equation must consist of up to 40 characters.
• The total number of channels and constants to be used for each equation is 16 or smaller.
