Prostat PFM-711A Electrostatic Field Meter

The PFM-711A Field Meter is an accurate electrostatic field measuring device. The PFM-711A circuitry is a digital, electronic chopper design, which allows the instrument to make electrostatic field measurements in areas where ionized air is present.For accurate, repeatable performance, the PFM-711A must be grounded during normal operations. Used by itself, the PFM-711A will measure electrostatic fields emanating from virtually any flat surface or object.

In the KV/INCH range, the PFM-711A will indicate electrostatic field voltage from 0 to ±20,000 volts in 10 volt increments at one inch distance from the charged surface.In the V/INCH range, the instrument measures field density from 0 to ±1,999 volts in 1 volt increments at one inch distance from the charged surface. The instrument is easy to use and its controls are designed for one hand operation.

The PFM-711A meter case is conductive. It provides the ground reference for its measuring circuit. For accurate measurements, it is necessary that the person holding the meter be properly grounded, or the meter has a ground connection made to the metal snap on the case.Ground the case by wearing a functional wrist strap that is properly grounded. Turn the meter on by selecting the desired range. Press the SAMPLE HOLD button down so that it latches in the lower or SAMPLE position, and HOLD is not indicated in the meter display. Adjust the display to zero (0) volts by rotating the ZERO control.

The ranging lights help position the instrument for accurate measurements. Align the front sensor of the PFM-711A Field Meter approximately one inch from the surface or object being measured. Move the instrument toward, or away from the surface until the RED Bulls Eye is focused on the test surface.Once the instrument is properly positioned, the PFM-711A will indicate the electrostatic field measured on its display. If desired, push the Sample/HOLD button (S2) once to lock the indication on the display. The HOLD indication will also appear on the instrument display.

The PFM-711A is the most flexible field meter in the ESD control marketplace. Combined with a variety of accessories, it can perform many different measurements to analyze the static sensitive process or environment.The analog output allows documentation of measurements when used in conjunction with X-Y plotter, analog data recording device, or the Prostat Autoanalysis System. (Recording device not supplied.)

SHIPPING

A delivery and handling charge applies to all orders with the exception of back-ordered items.

Unless otherwise required by Buyer, Seller will make transport arrangements as follows:

For deliveries within the metropolitan areas of mainland State capital cities a standard freight charge may be added to invoice; goods

For delivery outside those areas, seller will select the transport to be used and prepay freight for Buyer. Seller will then bill Buyer for freight at Seller's discretion.

Should the Buyer request goods be sent to a Post Office box the Buyer acknowledges this method is the only available and therefore the Seller is not liable for undelivered goods.

Free shipping on orders over $199 incl GST (valid for 1 delivery per order and excludes NT, WA & TAS). If only part of the order is in stock, the customer has the option of paying for a second delivery if they require a partial shipment prior to all goods becoming available. Mektronics Australia reserves the right to charge additional freight in the event of hazardous, bulky or heavy items ordered.

DELIVERY TIME

All quoted delivery or consignment dates are estimates only, given without engagement.

Delay in consignment of any part of an order shall not relieve Buyer of its obligation to accept and pay for the remainder of the order.

Except as provided in paragraph 1.2 of Terms & Conditions, seller will not be liable to pay damages or compensation for any injury or loss sustained by Buyer

a) in the event of a delay in consignment or delivery of goods: or

b) in the event of non delivery.

Goods offered ex-stock by Seller are subject to prior sale.

In the event of any happening beyond Seller's reasonable control in consequence of which Seller cannot effect consignment by the time or times quoted or specified, Seller shall be entitled to consign part only of an order, suspend consignment or extend the time for consignment, for the period during which such cause of delay operates, or may cancel the order, and in the event of such suspension, extension or cancellation, Seller shall not be liable for damages.
