The amazing RRampMeter designed for Model Railroaders by Tony’s Train Xchange does what no other meter can do!

Easy walk-around measurements of layout voltage drops, accurate booster output setup to optimum voltages for decoders and sound units.

• The only inexpensive device that accurately measures DCC Volts/Amps.
• Also measures AC and DC Volts/Amps.
• Rated at 10 or 20 Amps, costs less than DVMs that cannot measure DCC.
• Measures true RMS Volts/Amps, +/- 2%.
• Suitable for all scales.
• No batteries required.
• Designed for Left/Right-hand use.
• PCB length 5.63"; Enclosure length 4", width 2", height 1.25"
• 3 Styles Available:
  1. Version I RRampMeter Circuit Module without enclosure (Fig. 2)
  2. Version II RRampMeter with Enclosure and Clip Leads (Fig. 3)
  3. Version III RRampmeter Same as II. with Battery backup for measurements below 7 Volts
  4. Version IV RRampmeterHP
     Same as III but for large Scale high voltage and current applications:
     DCC: 38.6 v and 18-20 Amps
     AC: 27.6 v and 18-20 Amps
     DC: 38.6 v and 18-20 Amps

"I have found it a valuable tool for troubleshooting layout and engine problems. If it only saves 1 sound decoder or booster, it has paid for itself."

• Adjustable contacts permit direct track voltage measurements for all scales.
• Test or Clip Leads (Fig. 3) can also be used for other applications.
• Test Leads or Layout Wiring can be conveniently connected to the rear screw/socket terminals (not shown).
• Designed as a portable troubleshooting tool or as a panel-mount meter (Fig. 1).
