For measurements greater than 1.0x10 ohms, use 100 volts NOTE: For optimal performance and accuracy, use the Prostat PRS-801 Resistance System in its AUTOMATIC Mode (either Default Mode 1 [Ohms], or Mode 2 [Exponential 1.0EXX/ Ohms] display). AUTOMATIC Mode will control test voltage, resistance range adjustment and electrification period automatically.
