Prostat PAS-853B Wide Range Ohmmeter

The PAS-853B is a constant voltage wide range ohmmeter designed specifically for ESD Plant Auditors who must make many measurements quickly while supporting ANSI/ESD S20.20 Program Standard and periodic verification requirements.

The PAS-853B performs in accordance with standard resistance measurement practices outlined in ANSI/ESD 541 Packaging and meets all audit requirements of ESD TR53.

Variable & Constant Test Voltages in Auto Mode:

• <10 Volts Variable from 0.01 to 9.9x103 ohms

• 10 Volts (±<5% Constant Voltage) from 1.0x104 to 9.99x105 ohms

• 100 Volts (±<2% Constant Voltage) from 1.0x106 to 9.99x1012 ohms

CONTROLS

ON/OFF Battery Bus Cut-off
Slide Switch ON SIDE OF CASE

ON: Energizes instrument and LCD displays Software Version then GO A with AUTO indication (Default)

OFF: Isolates battery and DC voltage from instrument controls and circuit. Use for transport and storage

TEST Pad
With Test Leads installed: Press once & Release.
Measurements performed automatically

In conjunction with MODE changes from Auto operation to Continuous

MODE Pad
Steps through Auto/Voltage ranges with each press of MODE Pad:

• AUTO: Default automatic resistance range & Voltage control
• <10V: Manual Operation 0.01 to =10V Test Voltage;
  • Resistance Range: 0.01E-1 to 9.99E9 O
• 10V: Manual Operation at 10V (Nominal, Semi-Constant)
  • Resistance Range: 0.98E4 to 9.99E10 O
• 100V: Manual Operation at 100V (±<5V) Constant Voltage
  • Resistance Range: 0.98E6 to 9.99E12 O
  • When data in HOLD, press MODE to terminate HOLD without changing operational mode
  • Press MODE with TEST to change from Auto to Continuous
  • Used to measure lead resistance (NULL)
  • Used by Prostat Authorized Technicians for Voltage Calibration

CONNECTIONS

Positive (+): Test Voltage (RED) – Supplies test voltage to electrodes/fixtures

Negative (-): Current sensing (BLACK) – Conducts current from electrode, fixtures or Ground to instrument

Chassis: Shielding connection to chassis (WHITE) – Reduces transmitted energy and effect on current measurement

Note: ¾ inch spacing between RED and BLACK accommodates dual banana BNC adapters

INDICATION

Colored LED’s indicate instrument operational MODE and Test Voltage (YELLOW) used for the current measurement, as well as measurement completion (GREEN LED).

• AUTO: ON during automatic operations; OFF in Manual mode
• <10V
• 10V
• 100V
• GREEN LED: Measurement hold

TEST VOLTAGES

Automatically selected and controlled in AUTO mode. May be manually selected by pressing MODE pad in the following order:

<10V Variable based on resistance load:

• Provides 0.001 to =10V
• Functional in AUTO within range 0.01 O - <1.0E+4 O
• Manual Operation Resistance Range: 0.01E-1 to 9.99E+9 O

10V Constant Voltage (Under Load):

• Test Voltage Varies ± <5% in AUTO or Manual Operations
• Functional in AUTO within range 1.0E+4O - <1.0E+6 O
• Manual Operation Resistance Range: 0.9E+4 to 9.99E+10 O

100V Constant Voltage (Under Load):

• Test Voltage Varies ± <2% in AUTO or Manual Operations
• Functional in AUTO within range 1.0E+6 O - <1.0E+13 O
• Manual Operation Resistance Range: 0.90E6 to 9.99E12 O
  Returns to Auto Mode

MODES OF OPERATIONS

GO A: Performs all automatic and manual voltage select functions, stops and displays measurements after Electrification Period (EP) is complete, then displays data with Green LED ON for 10 seconds.

GO C: Performs all automatic and manual voltage select functions, continuously displays measurements until the operator presses MODE or TEST pads. GO Cdisables electrification period controls.

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.
