Data Collection And Data Retrieval; Consistency Calibration; Entering Laboratory Values To The Transmitter - Satron Instruments VC Quick Start Manual

Data Collection and Data Retrieval

The mill's standard for collecting consistency samples should be enough. The TAPPI T 240 standard is a
good reference.
Note: The sample extraction location should be located as close as possible to the transmitter for the best
results. Normally located 0,5 meters downstream of the transmitter.
The first component to accurately calibrate the transmitter is to employ consistent sampling and laboratory
techniques. It is valuable if the sampling can be scheduled so that the same person collects and tests the
samples during the data gathering period (consistency). This minimizes sample variability.
The second component to successful data collection is the accurate time correlation between when the
sample is taken, and the internal raw readings made by the transmitter. It is recommended that two people
work together to collect the samples. One person is the sampler/tester that will physically collect the sample
and the second person is at the RDU (or Sampling switch) to initiate the transmitter data collection period
and time stamp the sampling and meter readings made while the sample is extracted.

Consistency Calibration

There are two methods to perform successful consistency calibration via RDU (these methods automatically
store new consistency parameters to current recipe):
1. One-point/offset method to match probe to current sample
2. Two-point sampling method for calculating offset and gain

Entering Laboratory Values to the Transmitter

In order to utilize calibration functions in the transmitter, the corresponding laboratory values for samples need to
be entered into the transmitter. Use the following procedure to enter the laboratory values:

Starting at the default PV display value; Press the ESC button.
Use the UP/DOWN arrows to move to the Calibration sub-menu and press
ENTER.
Use the UP/DOWN arrows to move to the Samples sub-menu and press
ENTER.
Use the UP/DOWN arrows to move to the corresponding sample and press
ENTER.
The LAB %CS will shortly appear in the display followed by the PV text.
Press the ENTER key to enter the laboratory values for the consistency.
Use the UP/DOWN arrows to place the decimal separator in the proper
location and press ENTER. A separator will appear to Indicate the digit that
will be modified. Use the UP/DOWN arrows to change the number and
press ENTER. The separator will move to the right position. Press ENTER
until the right-hand digit is indicated and press ENTER one more time.
When SAVE? appears in the display, press ENTER to accept or ESC to exit
without saving.
