Welcome to the Truegauge Demo !

The following programs are included.

TG.exe - Truegauge Demonstration program that runs under Windows 3.1(TM).
CALIB.exe - Truegauge A/D converter calibration program that runs in DOS.
CALIB.bas - Source code for calibration program. Note, you are free to 
            copy and modify this code to suit your own needs.

The Truegauge demonstration program requires only the equipment supplied
in the Truegauge demonstration kit (DV114001) to run. 

However, the following user supplied equipment is required to run the
Calibration program and properly calibrate the A/D converter on a Truegauge
module. Additionally, the Truegauge module must not be connected to a 
battery or thermistor. Note, all modules supplied in the DV114001 kit are
already calibrated as delivered. 
1. Variable Power Supply 0-14V, 0-1.00A , minimum.
2. Digital Multi-Meter, 4.5 digit preferred. 
3. Fixed resistors or fine control potentiometer to simulate a thermistor
   at 10 and 40 degrees Celsius. Note for the thermistor supplied with the
   Truegauge modules in the kit these values are 207,807 and 51,058 ohms 
   respectively.


DEMO SOFTWARE (TG.EXE) REVISION INFORMATION:
 The Truegauge demo Revision 2.1 includes the following upgrades.
 This version is derived from the 2.0 version. 

Cosmetic Changes.
1.  Changed color of gauge bar to yellow when fast charging battery,
    blue when trickle charging, red when discharging, and black any
    other time.
2.  Added Comm port indication to main battery parameter display box 
    on run screen.
3.  Added limiter to estimated discharge time to prevent estimated time
    overflows when discharging at very low discharge rate (e.g. -1mA).
4.  Added Com port number identifier to all RS232 error messages.
5.  Added another (second) level of warning to download eepprom function
    if *_def.h8m file is selected. Improved messages to first warning 
    level message.
6.  Main screen is now hidden when Run screen is opened so that minimizing 
    the Run screen minimizes the whole application.
7.  Added duplicate status bar to bottom of run screen so that status 
    is visible when Main screen is hidden.
8.  Made capacity gauge bar visible when at 0%
9.  Put month-day-year identifier in data log file.
10. The gauge that indicates EEPROM read/write progress now disappears 
    when action is complete.
11. Added byte11 and byte12 of data packet to log file.

Truegauge Data Functional Changes.
1.  Changed the basis for self discharge table to 138 seconds per 
    self-discharge compensation calculation. To coincide with 
    the internal calculation that the MTA11200 performs. Previously
    the % per day charge loss as shown by the informational line 
    below the table used a 70 second basis.
2.  Added convert temperature to negative temp if greater than 128 degrees.
3.  Changed Self-discharge .vs. Temperature table for lead acid batteries
    in Pb_def.h8m Truegauge EEPROM default data file. Changed revision
    identifier for Pb_def.h8m file to 2 from 1. 

Windows Demo Functional Changes. 
1.  Removed EEPROM unlocked restriction (writecheck) to forcing gauge 
    to 100%.
2.  Fixed intermittent overflow condition in object tmrplot.
3.  Removed restriction to manually stop polling mode before downloading,
    now program waits until polling is complete (if in progress) then
    disables the polling timer, does the download and then re-enables 
    the polling timer.
4.  Prevent Run and Gauge and Upload and Download menu bar items from 
    being enabled until responses to s/w version, eeprom lock state,
    and broadcast interval from TG are received when communication 
    is first established.
5.  Installed patch to cure rare condition where numerical (e.g. 47%)
    display of state of charge quits updating even though % capacity 
    is being received Truegauge and is properly plotted on graph.
6.  Fixed condition where estimated discharge time remaining display 
    would quit updating when PC system time went past midnight.
7.  Changed End of Discharge (EODV) slider on Parameters screen to allow
    full (see MTA11200 data sheet, EODV system parameter) 0 to 65 volt 
    range in EODV.
8.  Changed Max Charge Time (OVTIM) slider on Parameters screen to allow
    full (see MTA11200 data sheet, OVTIM system parameter) 0 to 1911 
    minute (0 to 1114660 seconds, rounded to nearest minute) range 
    in OVTIM parameter.


CALIBRATION SOFTWARE (CALIB.EXE) REVISION INFORMATION:
 The Calibration program supplied with revision 2.1 of the Demo program 
 includes the following upgrades.
 This version is derived from the version distributed with the 2.0 revision
 of the Demo program. 

1. Upgraded temperature calibration to allow for negative temperature 
   readings.
2. Upgraded checks to determine that the operator actually changed the 
   applied voltage, current, or simulated temperature when requested 
   before proceeding with next step of calibration procedure.
3. Altered display of physical units on the top-of-page form.
