PGA-710 Autoanalysis System – How To Measure Guide 5
The shielded measurement cable is intented for use with the Prostat CPM-720 charge plate
monitor for measuring body voltage generation, charge retention, remote equipment and other
electrostatic voltage sources. The signal conductor insulation is Red and the shield insulation is
Green. Connect the Red lead to the CPM and object being measured. Connect the Green shield
to ground to reduce the effects of ambient electrical noise and transmitted energy. Do not
connect the shield to the ground plate of the CPM.
II. Instrument Setup for Body Voltage
The following outline will help prepare your system for capturing and recording data. To
protect your system, please review the following before proceeding further.
NOTE: The PGA-710 was designed to be used in conjunction with PROSTAT instruments,
specifically the PFM-711A Field Meter equipped with the CPM-720 Charge Plate Monitor
accessory. However, other devices having specified tolerances and output voltages ±2 volts
or less may be used with the PROSTAT PGA-710 Autoanalysis System. Confirm that the
measurement instrument’s maximum output voltage does not exceed 2.0 volts and that
connections are compatible before using other instruments with the PGA-710. If there is any
doubt about instrument compatibility, contact PROSTAT before connecting the instrument,
as damage incurred by using other instruments with the PGA-710 may void your warranty.
Set up your instrument for capturing data as follows:
1. Attach the PROSTAT CPM-720 Charge Plate to the
PFM-711A Field Meter
2. Ground the instrument. Mount a fabric PROSTAT
PWS-610M Modified Wrist strap to a 5 pound NFPA
electrode, and connect the wrist strap cord to a
previously tested ESD ground as shown in Figure 2,
below. (See ESD S-6.1 Grounding for details
regarding ESD grounds.)
CAUTION: To prevent damage to the PGA-710 and voiding your warranty, input to the
Autoanalyzer may not exceed 2.0 volts without specific adjustments and recommendations
from PROSTAT. Confirm proper non-PROSTAT instrument output voltages before connecting
to, and energizing the system.
