- Page 2 To avoid electric shock, never touch the inside of this apparatus. Only a qualified technician should open this apparatus. Do not drop or strike the product. If the product is damaged, contact a Prostat Authorized Service Center. This apparatus may produce voltages which may damage some electronic components. Remove any such components from vicinity before operating this apparatus.
- Page 3 Do not exert any pressure on the LCD display from the top. In rare cases cleaning the PFM-711B, case and display with a slightly dampened cloth may be required. Should this be required, use a very weak solution on of liquid soap and water. The cloth should be barely damp.
- Page 4 By attaching a CPM-720B Charge Plate to the PFM-711B, the meter can also be used for Ion Balance voltage measurements.

Page 5: Getting Started
02 GETTING STARTED PFM-711B Pushbuttons The PFM-711B has four (4) button switches to perform many functions: Button Color Name Function Press once (short press to turn the meter ON. White POWER Press and hold for 2 seconds (long press) to turn the meter OFF. -
Page 6: Display Features
Display Features The LCD is a large 3.5 digit reflective display: Figure 1. Display Features (PFM-711B) Number Feature Indication Digital numerical value. Negative polarity. Decimal point. Visible in high range (kV/Inch) range only. Indicates low battery. Table 2. Display Features (PFM-711B) -
Page 7: Battery Installation
Battery Installation The PFM-711B uses one (1) 9 VDC alkaline battery (included), which provides an approximate life of 30 hours. To install or replace the battery, follow this procedure: 1. On the back of the meter, there’s a battery compartment. Carefully press down the cover using its grooves. -
Page 8: Zero Adjustment
A blue ZERO button switch on the front panel can be used to adjust the reading to zero (0.00) if the field meter reading is not zero. To make PFM-711B read zero in this condition, press and hold the ZERO button pointing the unit away from charged surfaces and objects. You may need to press and hold the zero button more than once to obtain zero (0.00). -
Page 9: Analog Output Mode
Data and mode information will be lost by turning the meter off. LED Ranging Lights The PFM-711B has two red LEDs on the front end of the meter to position the unit at the right distance from a charged object. -
Page 10: Operation
Confirm that the instrument’s display is activated and that the battery low indication ( ) is not displayed. If low battery is displayed, replace the battery. The two LED ranging lights beside the sensor, also, turn on and the PFM-711B is ready for static charge measurement. CAUTION! The plastic case of the PFM-711B is made of conductive resin. -
Page 11: Operational Note
Figure 3. Operator properly grounded to use the PFM-711B OPERATIONAL NOTE The case of PFM-711B Field Meter is conductive and part of the instrument’s grounding circuit. If one holds the meter in one hand, and attempts to measure voltage on the other hand, no reading can be obtained regardless of body voltage. - Page 12 NOTE Each CPM-720B is calibrated at the factory to match its respective PFM-711B Field Meter. Do not modify the CPM-720B calibration adjustment without following factory Calibration procedure. Matched PFM-711B and CPM-720B units have the same serial numbers. Do not interchange.
- Page 13 Figure 4. Sliding the CPM-720B onto the PFM-711B NOTE Initial mounting of the CPM-720B Charge Plate Assembly to the PFM-711B Field Meter case may be extremely snug. Be sure that the plate and meter case grooves are perfectly matched before mating the two instruments together.

The CPM-720B’s mounted onto the PFM-711B PCS-730B Electrostatic Charger Combining this unique assembly with the PCS-730B Electrostatic Charger, you can easily confirm ionizer performance, plot decay times, measure suppression, and perform a variety of other electrostatic evaluations and demonstrations.
- Page 15 Once the PFM-711B Field Meter and CPM-720B Charge Plate are assembled, the PCS-730B Electrostatic Charger will apply a defined electrostatic voltage to the CPM-720B plate. PCS-730B Pushbuttons The PCS-730B has two (2) button switches to charge the plate assembly: Button...
- Page 16 Figure 6. Battery Replacement (PCS-730B) Low Battery Indicator The front of the PCS-730B includes a red LED that will illuminate when the battery reaches approximately 7.7 DC volts. It is important that you replace the battery when the LED is illuminated, so that the meter is able to charge the plate assembly to at least 1000 volts.
- Page 17 CPM-720B Charge Plate Assembly and charge the CPM-720B to approximately + 1.25kV ±5%. 6. Discharge the upper plate to ground, or short the upper and lower plates, until the PFM-711B meter reads zero (0.00).
- Page 18 Ion Balance Measurement The PFM-711B can easily be used to check the ion balance voltage (offset voltage) for many kind of ionizers using the CPM-720B Charge Plate Assembly. 1. Allow the ionizer to be measured to operate at normal speed for a minimum of 30 minutes prior to measuring balance.
- Page 19 3. Ground the case of the PFM-711B, as described below: a. If the operator is wearing a properly grounded wrist strap and making direct contact with the metal ground snap mounted on the back of the PFM-711B’s case, the unit will be sufficiently grounded.
- Page 20 PGA- 710B Autoanalysis System or a PDT-740B Decay Timer. a. Select the V/inch range on the PFM-711B Field Meter and zero (0) the unit, ±2 volts to ground. This will provide the most precise voltage indication. However, the instrument meter indication is dampened so that time of decay will be slower than actual decay time.
- Page 21 The use of the Prostat PWS-610M is recommended for this application due to its built-in 10mm male snap so that connects to the grounding female snap on the back of the PFM-711B meter. b. Remove the insulated cap covering the 10 mm male snap located in the cuff fabric approximately 1.5 inches from the cuff buckle.
- Page 22 4. Select the range you wish to use for measuring body voltage generation. a. Select the V/inch range on the PFM-711B Field Meter and zero the unit, ±2 volts to ground. This will provide the slowest indication of body voltage indication due to meter dampening.
- Page 23 The case has been sealed and BREAKING THE SEALS WILL VOID THE WARRANTY. If for any reason you believe the meter is not working correctly, contact Prostat or an Authorized Calibration Lab for assistance.

Page 24: Troubleshooting
If you don’t hear a sound coming from it, then the sensor is defective and needs to be serviced The PFM-711B is displaying erratic readings The accuracy of the PFM-711B might be affected by the static charge on the person making the measurement if the meter is not properly grounded. For proper measurement, the operator should be grounded using a wrist strap and making direct contact with the metal ground snap mounted on the back of the PFM-711B. - Page 25 the voltage is less than 7.2 volts, replace the battery. The PCS-730B will not output 1,000 volts The PCS-730B is designed to output ±1,250 Volts ±5%. If the charger will not output at least 1,000 volts, the battery may be too low. We recommend measuring the voltage of the battery with a multimeter.
