Test Point
The Test Point is the voltage value that is input or output for verification
purposes. This value is broken down into Location and Value. Location
refers to where the test value fits within the test range. Pos FS refers to
positive full-scale, and Neg FS refers to negative full-scale. Value refers to
the voltage to be verified, and Zero refers to the outputting of zero volts.
24-Hour Ranges
The 24-Hour Range column contains the upper limits and lower limits for
the test point value. If the device has been calibrated in the last 24 hours,
the test point value should fall between the upper and lower limit values.
These limit values are expressed in volts.
1-Year Ranges
The 1-Year Range column contains the upper limits and lower limits for the
test point value. If the device has been calibrated in the last year, the test
point value should fall between the upper and lower limit values. These
limits are expressed in volts.
Counters
Because you cannot adjust the resolution of the counter/timers, these values
do not have a 1-year or 24-hour calibration period. However, the test point
and upper and lower limits are provided for verification purposes.
