Use of calculation formula
Each function of the multimeter can display recalculated measured value. The value shown on the display is
always calculated according to the formula:
Y = A0 + A1*X + A2 * X
2
where
X is the value measured by the multimeter
Y is the value shown on the display
Default setting of the coefficients is A0 = 0, A1 = 1, A2 = 0. This means that directly measured value is
displayed on the display. If any other recalculation is required, enter the desired parameters. Parameter A0 must
be of the same dimension as is in row UNIT.
•
Press METER direct control button and select A0 (A1, A2) option from the menu using cursor buttons.
