Activate the wide range, resistance instrument to obtain a measurement. In the case where the PRS-801B is the measurement instrument, it should measure 1.00x10...
  • Page 9 For measurements greater than 1.0x10 ohms, use 100 volts NOTE: For optimal performance and accuracy, use the Prostat PRS-801B 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.

    A proper measurement would include placing the material, or device under test (DUT), onto a clean metal test bed that is isolated from ground, such as the Prostat PTB-920 Test Bed. This insures that only the material is being measured and the measurement is not affected by voltage variables on ground.

    PRF-922B Miniature Two-Point Probe Set charges on its surface. The Operator should also be properly grounded to avoid body charges influencing the measurement. The metal test bed is connected to the resistance instruments positive (+) terminal, which provides volt- age to the test bed during the measurement. The micro probe shielded cable with installed BNC/Banana Adapter is connected to the resistance instruments negative (-) terminal.
