  • Page 3 PFK-100 Field Meter Set I. Introduction The PFM-711A is an accurate, compact electrostatic fieldmeter used for locating and measuring static charge potentials. The Charge Plate Assembly CPM-720A allows the PFM-711A to be used to balance & Monitor air ionization equipment, and generally function as a Charge Plate Monitor (CPM). Using the PCS-730 Charging Source, decay performance of ionizers, materials and other equipment may be measured.

With the PFM-711A Field Meter controls and the CPM-720A sensing plate facing up (the lower plate has a cutout for the meter), carefully slide the CPM-720A’s lower ground plate into the LOWER mounting grooves molded into the sides of the PFM- 711A’s case.

  • Page 10: Operational Requirement

    PFM-100 Field Meter Set OPERATIONAL REQUIREMENT Cases of PFM-711A field meter and PCS-730 charging source MUST be grounded for proper operation . 4. With the operator’s fingers contacting the grounding snap on the back of the PFM-711A Field Meter unit, slide the three position (kV/inch, OFF, V/inch) RANGE/POWER switch (s1) to the kV/inch position.
  • Page 11 PFK-100 Field Meter Set F. PCS-730 Charging Source Preparation for Use 1. Install provided 9 volt battery by sliding battery com- partment open and firmly snapping battery terminals to the appropriate connectors. Battery can only be con- nected in one way. Carefully re-close the battery com- partment.
  • Page 12 PFM-100 Field Meter Set Assembly and Charge the CPM-720A to approximately +1.20kV. 7. Discharge the upper plate to ground, or short the upper and lower plates, until the PFM-711A meter reads zero. 8. With the operator’s fingers contacting the metal ground- ing snap on the back of the PCS-730 Charging Source, press the three position rocker switch to the rear, -kV position.
