CAV DATA TABLE
The CAV 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 known and calculated KV
„
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: maximum drop time - minimum
drop time
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 = 0.2
