DATA TABLE
The sample analysis is designed to permit convenient viewing of data
collected from samples which have been tested using the Measure
Sample Viscosity sample action option.
The sample analysis displays sample data in a tabular format. In addition
to Sample identification (ID), the following data may be included:
INV—Invalid test indication (flow time out of tolerance)
Tol[erance]—Acceptable difference in multiple test results for the
same sample
Date—Date the sample was measured
Time—Time the sample was measured
Tube S/N—Tube serial number (from Instrument Settings)
Tray [Index]—Position of the sample tray in the numeric sequence
(left to right)
Smple Indx.—Position of the sample in the sample tray
Bulb No.—Bulb number (the bulb in which the sample was run—#1
is the bottom bulb)
Technician—The technician logged on to VISCPRO at the test time
Instrument Type—Instrument type (CAV, CCS, etc.)
Instrument ID—Instrument Identification (from Instrument Settings)
KV—Average kinematic viscosity (calculated from flow times)
Known KV—Known kinematic viscosity of the viscosity standard
% Diff KV—Percent difference between the measured KV and the
known KV for viscosity standards
Temp[erature]—Average bath temperature
T1-T4—Bath temperature during each sample drop
% Diff —For multi-drop samples: ((maximum drop time - minimum
drop time) / average drop time) * 100
EXAMPLE: Four drop times: 80.3, 80.4, 80.5, 80.5
Maximum drop time = 80.5
Minimum drop time = 80.3
((80.5 - 80.3)/80.425) * 100 = 0.2487
Abs. Diff—For multi-drop samples: the absolute value of the differ-
ence between the accepted drop time value furthest from the average
drop time and the average drop time value itself.
EXAMPLE: Four drop times: 80.3, 80.4, 80.5, 80.5
Average drop time = 80.425
Furthest drop time from average = 80.3
|80.425 - 80.3| = 0.125
