Application Hints
(Continued)
Non-Interacting Adjustments for Expanded Scale Meter (4.5V to 5V, Bar or Dot Mode)
Adjusting Linearity of Several Stacked Dividers
Other Applications
• “Slow” — fade bar or dot display (doubles resolution)
• 20-step meter with single pot brightness control
• 10-step (or multiples) programmer
• Multi-step or “staging” controller
• Combined controller and process deviation meter
• Direction and rate indicator (to add to DVMs)
• Exclamation point display for power saving

• Graduations can be added to dot displays. Dimly light
every other LED using a resistor to ground
• Electronic “meter-relay” — display could be circle or semi-
circle
• Moving “hole” display — indicator LED is dark, rest of bar
lit
• Drives vacuum-fluorescent and LCDs using added pas-
sive parts
