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
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.
•
Enter new value using numeric keyboard.
•
Confirm the value by pressing ENTER.
•
After setting the coefficients, use ∧ or ∨ cursor buttons to switch to the previous or next menu option. The
same can be achieved using the potentiometer after pressing the knob. Press EXIT display button the close
the range selection menu and to return to the basic display.
If you want to reset a coefficient to original setting, press CLR display button.
Each measurement function of the multimeter has its own independent set of coefficients.
Setting function parameters
Some measurement functions have additional parameters. When measuring the temperature using RTD sensors,
R0 (resistance at 0 °C) can be set, when measuring the temperature using TC sensors, the temperature of cold
junction can be set and when measuring using SGS sensors, supply voltage of the bridge can be set.
Original settings are listed below:
T RTD
T TC
SGS
The parameters can be changed as follows:
•
Press METER direct control button and select a function, then use cursor buttons to select the line which
includes the function parameter.
•
Enter new value using numeric keyboard.
•
Confirm the value by pressing ENTER.
•
After setting the coefficients, use ∧ or ∨ cursor buttons to switch to the previous or next menu option. The
same can be achieved using the potentiometer after pressing the knob. Press EXIT display button the close
the range selection menu and to return to the basic display.
