CPM-720A Charge Plate Assembly

Converts PFM-711A Field Meter to a portable, battery operated charged plate monitor (CPM)

The CPM-720A Charge Plate Assembly is a miniature isolated plate attachment for the PFM-711A Field Meter. It converts the PFM-711A Field Meter into a portable, battery operated charged plate monitor (CPM). This unique design allows precision balancing of ionizing blowers and other devices to less than ±2 volts accuracy.

When used with auxiliary leads or wrist strap, the CPM-720A measures body voltage and equipment charge generation. Combining this unique assembly with the PROSTAT PCS-730 Charging Source, one can easily confirm ionizer performance, plot decay times, measure suppression, and perform a variety of other electrostatic evaluations and demonstrations.

SPECIFICATIONS:
Isolated Plate:
Stainless Steel parallel plates, 3.25 inches square. Auxiliary female jack installed.

Capacitance:
Plate Capacitance 10 picofarads (pF) ± 1 pF

Range:
0 to ± 6 KV at a plate separation of 0.60 inch.

Accuracy:
± 2% at 1,000 volts. Calibration adjustment screw provided.

Grounding:
Through conductive case and snap fastener of Model PFM-711A.

Dimensions:
Length: 3.25" (8.3 cm)
Width: 3.25" (8.3 cm)
Depth: 0.9" (2.3 cm)

Weight:
8 oz.
