6: Reading buffers 2470 High Voltage SourceMeter Instrument
6-20 2470-901-01 Rev. A / May 2019
An F in a column indicates the corresponding heading item is false for that reading. For example, if an
F i
s listed in the Math column, it indicates that the item was not used or did not occur on that reading.
A T in a column indicates that the corresponding heading item is true for that reading. For example, if
a T is listed in the Math column, it indicates that the item was applied to that reading.
Heading Description
Provides an identifier for each reading
Measured value for each reading
Indicates the unit of measure for the reading; values may be any of the
following: Volt, Amp, Ohm, or Watt
Positive full-scale value of the measurement range that the instrument is
presently using; values may be any of the following:
".000000001", ".00000001", ".0000001",
".000001", ".00001", ".0001", ".001", ".01",
".1", "1", "10", "100", "1000", "10000", "100000",
"1000000", "10000000", "100000000", "1000000000",
"10000000000", "100000000000"
Disp Digits
The number of digits that are displayed for measurements on the front
panel. Values may be
,
,
, or
T when Math is ON; F when Math is off
Specifies that the upper limit for limit 1 has been exceeded
Specifies that the lower limit for limit 1 has been exceeded
Specifies that the upper limit for limit 2 has been exceeded
Specifies that the lower limit for limit 2 has been exceeded
Specifies which set of input and output terminals the instrument was
using when the measurements were made; values may be any of the
following:
or
Origin
The A/D converter from which the reading originated; for the 2470, this
Value is the source value when the reading was taken; if readback is
ON, it is the measured source value; otherwise, it is the programmed
Units of measure of the source; values may be any of the following:
Volt, Amp, Ohm, or Watt
T indicates that the source limit was exceeded; F indicates that the
source limit was not exceeded
T indicates that the instrument is in an overtemperature state; F indicates
that the instrument is not in an overtemperature state
Date the readings were made
Time the readings were made
Fractional portion of the timestamp (in seconds) when each reading was
made; fractional seconds are the fractional part of an absolute
timestamp, for example, the fractional part of the 11:11:23.45678
