4. Variable
Users can set the desired values of Variable1 and Variable2. Press Variable and
turn on the setting menu as follows.
Variable: press this softkey to select the variable to be set as "Variable1"

and "Variable2".
Step: press this softkey to set the step used when using the knob to modify

the "Mantissa". The steps available are × 1, × 0.1, × 0.01, × 0.001 and ×
0.0001.
Mantissa: press this softkey to set the number of significant digits of the

variable. After setting the "Step" and pressing this softkey, turn the knob to
modify this parameter. The range available is from -9.9999 to 9.9999.

source. You can use differentiate to measure the
instantaneous slope of a waveform.
Calculate the natural logarithm of the selected source (use
constant e (approximately 2.718282) as the base
Calculate the natural logarithm of the selected source (use
constant e (approximately 10) as the base).
Calculate the exponent of the selected source. For example,
Exp(A) means calculate the Ath power of e.
Calculate the square root of the selected source.
Calculate the absolute value of the source selected.
Calculate the square value of the source selected.
