Using the Built-in Calculator For solving mathematical equations that involve the calibrator's source or measured value, you can use the calibrator's built-in calculator. The present measure and source values, including units, are always available to be inserted into an equation at a single keystroke. The calibrator keeps measuring and sourcing during calculator operation. Start the calculator from the SOURCE, MEASURE, or MEASURE/SOURCE mode by pressing the Calc softkey. You may have to press More Choices to get the Calc softkey. After you press Calc, the display, number keys, and keys with calculator functions (L, R, u, d, rand e) become an algebraic-entry calculator.

Using the Built-in Calculator
For solving mathematical equations that involve the
calibrator’s source or measured value, you can use
the calibrator’s built-in calculator. The present
measure and source values, including units, are
always available to be inserted into an equation at a
single keystroke. The calibrator keeps measuring
and sourcing during calculator operation.
Start the calculator from the SOURCE, MEASURE,
or MEASURE/SOURCE mode by pressing the
Calc
softkey. You may have to press
More Choices
to get
the
Calc
softkey.
After you press
Calc
, the display, number keys, and
keys with calculator functions (
L
,
R
,
u
,
d
,
r
and
e
) become an algebraic-entry calculator.
Press
Done
when you want to resume normal
calibrator operation.
Saving to and Recalling from the
Registers
When the calibrator is in calculator mode, the top half
of the display shows three register names and their
contents:
•
MEASURE
(the present measured value)
•
SOURCE
(the present sourced value)
•
REGISTER
(temporary storage for your use)
Insert the contents of any register into a calculation
by pressing the
Recall
softkey followed by the softkey
for the desired register.
Press
Store
to copy the number from the calculator
display (lower half) into
REGISTER
to temporarily
save the number for later use, or into
SOURCE
.
