  • Page 4: Introduction

    ESD control products. The PDT-740B Static Decay Timer is used with Prostat’s precision portable Charge Plate Monitor kit com- ponents, including the PFM-711A Field Meter, CPM-720A Charge Plate Assembly and PCS-730 ±1kV Charg- ing Source.

  • Page 5: Function

    The PDT-740B is designed specifically to measure decay time of ionizers and materials in seconds and tenths of a second from 1,000 to 100, 50 or 10 volts. It is used with the Prostat PFM-711A Field Meter and CPM-720 Charge Plate Monitor Assembly, or an equivalent instrument having an analog output of 1 volt equaling 10,000 electrostatic volts.

    1. Insert one cable mini-phono plug into the PFM-711A Analog Output receptacle located on the left front panel of the instrument. 2. Insert the opposite end of the cable into the PDT-740B Analog Input receptacle located on the left front panel of the instrument.

  • Page 7: Normal Operation For Ionization Static Decay Measurements

    The dual phono plug cable assembly is connected to the analog output of the PFM-711A Field Meter and the Analog Input of the PDT-740B Decay Timer. With the Charge Plate Assembly (CPM) installed on the Field Meter, the Charging Source is used to apply greater than ±1,000 volts to the CPM. To measure an ionizers decay time performance, proceed as follows: A.
