5.6.4 DERIVED VARIABLE CONFIGURATION
DV NUMBER
Derived Var. ?
N
The up/down arrow keys are used to select a DV for configuration. Each optional derived channel brings with it
the ability to define three DV’s.
DV FUNCTION

The Up/Down arrow keys are used to select a derived variable function
DV SOURCE SELECT
DV1 Input 1
Constant
The Up/Down arrow keys are used to select: Input Channel, DV 1 to 9 or constant.
CONSTANT ENTRY
These displays appear only if ‘Constant’ has been selected as one of the DV’s inputs.
DV1 Const.?
N
The up/down arrow keys are used to scroll through inputs that have been chosen as constants, above. Operation
of the ENTER key calls the mantissa and exponent pages for the constant.
Constants are entered on two pages; the mantissa page and the exponent (power of 10) page. The constant is
entered as a number between 0 and 9.9999 on the mantissa page, followed on the exponent page by the relevant
power of 10, (in the range -30 to +30). Thus, a constant of 6.25 would have an entry in the mantissa page of
6.2500, and an exponent of 0. A constant of 625 would have a mantissa of 6.2500, but with an exponent value of
2, and a constant of 6,250,625 would have a mantissa of 6.2506, with an exponent value of 6.
DV1 Input 1
_1.0000 Mant.
CLEAR returns to the ‘DV1 Const.?’ display above. ENTER, followed by page scroll calls the exponent page.
DV1 Input 1
_2 Exp.
The up/down/side arrows are used to enter the mantissa and exponent values.CLEAR returns to the ‘DV1 Const.?’
display above. ENTER, followed by page scroll re-calls the mantissa page.
