2. Press the MORE soft key.
3. Press the HIGH INPUT Z soft key.
The Meter is capable of performing mathematical operations with measured values, as
well as tracking a series of measurements. With the exception of Diode Test and
Continuity, all Meter functions work with all analysis functions. The mathematical
functions include statistics, limits, offset, and mX + b. Meter measurement tracking is
performed through the TrendPlot and Histogram functions.
To access the analyze functions press J.
The statistical analysis function displays the minimum and maximum measurements of a
series of Meter measurements. The Meter also calculates an average and a standard
deviation value for the same measurement series. This function also provides control over
the starting and stopping of the measurement series.
To start the statistics process:
1. Press J to display the Meter’s analysis menu.
2. Press the STATS soft key.
While a series of measurements are being collected, the process can be stopped by
pressing the STOP soft key. To start calculations on another series of measurements,
press the RESTART soft key.
As the measurements are collected, the display is continually updated with the latest
statistical data as shown below.
The minimum, maximum, average, and standard deviation is displayed along with the
number of measurements the statistics were calculated on.
The soft key label becomes highlighted to indicate high input Z is activated. Press the
soft key again to disable the function.
The Meter starts collecting data immediately. Individual readings are never stored in
the Meter, but each reading is added to the Average and Standard Deviation
calculation. At the same time, the measured value is compared to the values stored in
the minimum and maximum registers, and overwrites one of these values if it is
lower than the minimum value or greater than the maximum value.
