Note
From any of the menus below, pressing the
Config key enters the MATH
CONFIG
menu; pressing the Math key reverts to the MATH menu.
Press
Enter or Quit to revert automatically to the MATH CONFIG menu.
 Causes a rolling average of
R
readings to be made. AvR cross-cancels with
BlocN.
 Causes a block average of N readings to be made. BlocN cross-cancels with
AvR.
 Causes the measurement to be multiplied by a constant, m.
− Causes a constan
t
, c, to be subtracted from the measurement.
 Causes the measurement to be divided by the constant, z.
 Causes the measurement to be expressed in dB relative to 1, or to z, or to
dBref.
Constants dBref and z are defined via the
MATH CONFIG menu.
 Causes the measurement to be multiplied by 100.
Math Configuration
Press the
Config key from the MATH menu to display the MATH CONFIG menu, from
which you can store the various constants used by the Math operations.

MATH CONFIG menu
The MATH CONFIG menu has six menu keys.
 Provides selection of the number of readings used in rolling average.
 Provides a numeric entry menu for the value of N. The most recent N value is
shown and the keyboard is activated. Press
Enter to store the new value or
Quit to leave the old value intact and return to the MATH CONFIG menu.
 Provides a numeric entry menu for the value of the multiplier constant, m.
 Provides a numeric entry menu for the value of the subtractor constant, c.
 Provides a numeric entry menu for the value of the divisor constant, z.
 Provides selection of the decibel reference constant, dBREF. Only voltage
functions can utilize all the settings. Other functions will utilize a unity
reference.
50 Ω Selects a reference of 1 mW in 50 Ω.
75 Ω Selects a reference of 1 mW in 75 Ω.
600 Ω Selects a reference of 1 mW in 600 Ω
1 Selects a unity reference value.
