AMETEK JOFRA IPI

Introduction

The IPI combines the high accuracy of digital electronics with the convenience and ease of use of an analog test gauge. Accurate to ±

0.05% FS, the IPI can be used as a calibration reference, or in any application where high accuracy pressure measurement is required.

Many user configurable functions have been designed into the IPI including sampling rate, TARE, damping, auto shut off, and min-max. Once the gauge is configured, settings can be locked and password protected to prevent unauthorized changes to configuration.

1.2 Standard Equipment

Check to see that your IPI has arrived intact. Batteries are factory installed unless you have purchased the optional 24V powered version, in which case batteries are not supplied or installed. Save the packing materials at least until you have verified that there is no concealed damage.

1.3 Safety information

A Warning identifies conditions and actions that pose hazard(s) to the user; a Caution identifies conditions and actions that may damage the Calibrator or the equipment under test.

Hazard Location Information

Ex Hazardous Areas

An Ex-hazardous area as used in this manual refers to an area made hazardous by the potential presence of flammable or explosive vapors. These areas are also referred to as hazardous locations, see NFPA 70 Article 500 or CSA C22.1 Section 18.

Certification

This product is certified by CSA with the following rating:

Class I, Div. 2, Groups A-D

Misuse

Should the BetaGauge be exposed to overpressure or sudden physical shock (i.e. being dropped) it should be examined for any damage that may

cause a safety concern. If in doubt please return the unit for evaluation to Ametek. Please refer to the Customer Service Section for contact information.

Caution

To avoid possible damage to calibrator or to equipment under test:

• If the message changes to "OL" the range limit is exceeded and the pressure source must immediately be removed from the IPI to prevent damage to the pressure transducer inside.

• Maximum torque allowed is 13,5 Nm = 10 ftlbs. NEVER exceed the torque allowed.

IPI Display and Controls

Operation

Power: The standard IPI is supplied with 3 AA batteries installed. If you purchased the optional 24Volt powered version, batteries are not installed. Connect a 24V power supply to the terminal block on the rear of the gauge, noting proper polarity. Do not install batteries when external power will be used.

Push the power button momentarily to turn the unit on. Push it again to turn it off.

Set-up and configuration:

Push the CONFIG button to access the user-settable functions on the gauge. Each time the CONFIG button is pressed; the display advances to the next

function. Once a function has been set, press ENTER to exit the configuration menu, or CONFIG to continue with further configuration. In order, the configuration menu and operation is as follows:

1. Engineering Units set. The unit is shipped configured to display PSI. By pressing the ▲ and ▼ (ZERO and MAX/MIN) keys you can scroll forward and backwards through the 18 standard engineering units plus a one custom unit/scale. When the desired unit is displayed, press ENTER or CONFIG. Pressure will now be displayed in the chosen engineering units.

See the Specifications section of this manual for a list of available engineering units. See the Supervisory Mode section for details on setting up custom units.

2. Set Auto Off. The auto-shut off can be set in 1 minute increments from 1 to 30 minutes or “off” (continuous operation). The unit is shipped set for 30 minutes. Use the ▲ and ▼ keys to set the desired interval. The “off” setting is at the low end of the choices, below 1 minute.

3. Display battery voltage. Actual voltage and a percent of life bargraph indicate battery condition

4. Display actual temperature. The IPI is temperature compensated, this displays the temperature measured by the internal sensor. The value can be set to degrees F or degrees C using the arrow keys.

5. Set damping. Choices are “on” and “off” set with the ▲ and ▼ keys. Turning damping on will smooth readings from pulsating pressure sources.

6. Set sample rate: This determines how often pressure is sampled and the display is updated. Choices are 0.5, 1, 3, and 10 samples/ second. Note that 10/sec provides the fastest response time.

7. Set TARE. This allows you to set a constant offset value, which is then subtracted from the measured pressure. For example if a TARE is set at 30 PSI, and the measured pressure is 37 PSI, the displayed value will be 7 PSI. A pressure of 27 PSI would be displayed as –3 PSI.

The tare value is set manually with the ▲ and ▼ keys, and is based on the engineering units and resolution selected for display. TARE value can be set to the maximum range of the gauge.

The bar graph will always display the actual pressure based on the full range of the gauge regardless of the tare setting. This is done for safety to insure that even with a “0” reading that pressure is being applied to the gauge.
