to calibrate the current loop 4mA output. Use an ammeter to measure the current loop
output current. At the same time, move

to adjust the displayed numbers. Watch the ammeter until it
reads 4.00. Stop at this point, the 4mA has been calibrated.
Then, press

to calibrate the current loop 20mA output. The method is as same as in 4mA calibration.
The result is saved in EEPROM. Switch off the power supply has not lost.

Flowmeter PORTABLE Software Usage
The Flowmeter PORTABLE software contains two parts: Flowmeter.apk that runs on the TPC and UFM Data
processing program working under Microsoft Windows operating system.
Under normal conditions, to complete all measurement tasks and data acquisition, data browsing and setup guide
operations, only the TPC software Flowmeter.apk is needed. If you need further data processing, copy the data
from TPC to your PC and carry out statistical analysis, graphic display, printing and other operations on the data
using UFM Data (UFM Data will be provided and will need to be installed in your PC).
Flowmeter.apk exploits the powerful computing capabilities of the TPC, offering the following functions in
addition to normal measurement:
Data Acquisition: Collects data from the Flowmeter and stores it in the memory of the TPC. The collected data
can be browsed in a table or graph on the TPC and simple analysis can be conducted.
Setup Guide: Allows the meter to be configured in steps with a setup wizard. Users can save the settings in a file,
which can be recalled directly later on to simplify the setup process. The setup guide greatly simplifies the
operation of the meter, allowing personnel who are unfamiliar with the Flowmeter to configure its settings easily.
Full Screen Display: The program has the ability to display MENU00~04 and shortcut keys Flow, Velo, +Total,
-Total in full screen view. Operators can check the data easily.

Data Acquisition and Analysis
5.12.1.1.
TPC Data Acquisition and Analysis Program
This program stores the collected data into the TPC
’
s Flash memory in the form of files.
For Flowmeter Portable kits equipped with the panel personal computer, the data is stored on the SD card. The
Data Files may be accessed by starting the
“
Card Reader
”
program while attached to your PC. This will allow you
to transfer the data files to your PC for use with the UFM Data program.
For those Flowmeter kits Equipped with the panel personal computer, the data files are stored in the following
directory in SD card. Remove the SD card from the TPC, connect it to the PC via the card reader, then will enter
below catalogue
：
TPC \programs\Data. You can see four directories: SL1188P, Display, Output, and Setup. The
“
SL1188P
”
directory is used for storing the collected Flowmeter data,
“
Output
”
for storing output setup files of
the Flowmeter,
“
Display
”
for storing the display setup files of the Flowmeter and
“
Setup
”
for storing setup and
configuration files of the Flowmeter.
During data acquisition, 1800 data points can be collected each hour (i.e. each data point requires 2 seconds). Data
amount for each hour is 144K. Assuming the data storage of the TPC is 1GB, each extension card is able to store
over 7200 hours of data points. If needed, users can choose extension cards with more storage.

Main Interface
The main menu is divided into three items: Flow, Key TPC and Config. Menus are further classified into six
modules: Data Acquisition, Table & Graph, UFM Data (internal SD card data acquisition) and Read file (read the
data in the SD card) are menus used to perform data acquisition and display data table and graph, while
Configuration, Display and Output are menus used for Flowmeter setup, about SL1188P display software
