VOLTAGE 

Model 235 Process Voltage Analyzer

• Calibrate Voltage Instruments—
  Simulate inputs and check outputs; automatically sources or sinks.
• Three Ranges—
  0.0 to 199.9 mV, 0.00 to 19.99 V & -25.0 to 199.9% of 1 to 5V.
• Calibrate 1 to 5V Receivers—
  Without breaking 4 to 20 mA loop just clip across the input resistor to calibrate the 1 to 5V receiver with no effect on the 4 to 20 mA signal.
• QUIK-CHEK Switch— 
  Instantly select HI & LO outputs.
• Basic Accuracy—
  ±(0.05% of Span + 1 LSD)— Accurate to 0.02V or 0.2 mV.
