Parameter On-screen Label Description/Options
Primary Measurement
Nominal Value
NOMA
Sets the nominal value of the primary measurement. This only
applies when in % mode.
Valid Range: Dependent on the measurement range of the se-
lected primary function.
Secondary Measurement
Nominal Value
NOMB
Sets the nominal value of the secondary measurement. This
only applies when in % mode.
Valid Range: Dependent on the measurement range of the se-
lected primary function.
Statistical Measurement
State
STAT
Enables/disables the statistical measurement function. If dis-
abled, statistical measurements are not taken even when initi-
ated or triggered.
Options: OFF, ON
Select Measurement Statis
Selects which measurement parameter to calculate for statisti-
cal measurements.
Options: A, B
A The primary measurement.
B The secondary measurement.
Measurement Samples Number
The total number of measurement samples to capture and to
be stored in before performing the statistical calculations.
Valid Range: 0 - 30000
Upper Limit Hi
The upper limit value for the statistical measurement calcula-
tion.
Valid Range: Dependent on the measurement range of the se-
lected function (primary or secondary depending on the Statis
parameter seing).
Primary Measurement
Low Limit
Lo
The lower limit value for the statistical measurement calcula-
tion.
Valid Range: Dependent on the measurement range of the se-
lected function (primary or secondary depending on the Statis
parameter seing).
