== 🔧 TROUBLESHOOTING ==
=== Issue 1: NVGate Shows "Disconnected" ===
<div style="background: #ffebee; border-left: 5px solid #d32f2f; padding: 20px; margin: 15px 0; border-radius: 5px;">
'''What it means:''' Application can't reach NVGate
'''Solutions (in order):'''
# Is NVGate actually open? Check your screen.
# Restart NVGate
# Restart the THD application
# Check Windows firewall allows localhost connections
# Call your IT department and cry
'''Reality check:''' 99% of the time NVGate just wasn't open. No shame, happens to everyone.
</div>
=== Issue 2: Measurement Won't Start ===
<div style="background: #fff3e0; border-left: 5px solid #f57c00; padding: 20px; margin: 15px 0; border-radius: 5px;">
'''What it means:''' Something blocking the measurement
'''Solutions:'''
# Click '''Run Diagnostic''' - it will tell you exactly what's wrong
# Common causes:
#* No sweep configured in NVGate
#* Markers not properly created
#* Wrong window names in configuration
The diagnostic is your friend. Use it!
</div>
=== Issue 3: THD Values Show "--.-" (dashes) ===
<div style="background: #e8f5e9; border-left: 5px solid #388e3c; padding: 20px; margin: 15px 0; border-radius: 5px;">
'''What it means:''' No data is being read from harmonics
'''Check these:'''
# Are FFT traces actually visible in NVGate? (Most common issue)
# Is the sweep running?
# Is there audio output to your speaker?
# Are markers properly set up?
Fix one of these and you're golden!
</div>
=== Issue 4: STOP Button Doesn't Work ===
<div style="background: #f3e5f5; border-left: 5px solid #7b1fa2; padding: 20px; margin: 15px 0; border-radius: 5px;">
'''What it means:''' Measurement is shutting down but taking its time
'''Solution:''' Wait 5 seconds. Seriously. The app is cleaning up.
If it still doesn't respond after 30 seconds:
# Close the window
# Restart the application
# Continue with life
</div>
