About This Manual

The bench-top UPS3000 and the rack-mountable UPS3110 and UPS3210 pneumatic pressure standards are rugged, compact instruments manufact ure d by COND EC. Th ey are designed to provide superior accuracy, range of calibration and ease of operation when used to assist in the manufacture, test and/or calibration of a wide variety of pressure sensing and measuring devices.
These instruments utilize an extremely repeatable sensor coupled to microprocessor-based electronic circuitry and a selectable units display system. This provides easily readable and accurate digital representation of the measured pressure. If required for portable use, the optional battery models, are able to provide up to six hours of use.
The UPS3110 all electro-mechanical device has our precision Orion vernier and one test port. Some models contain a front panel gage, to show the operator the input pressure, as well as, a pressure regulator that will act as a pressure limiter so that the operator can not over pressure a unit under test. A test hose is supplied for the customer. Standa rd fro nt pane l buttons and switches provide selection of the desired pressure range, push-button zeroing and the unique internal self-check feature.
This manual has been written to give the user a simple and clear explanation of how to operate, calibrate and maintain these instruments.
Before attempting to use either style, Pressure Standard, the following instructions
#AUTION
must be carefully read and understood by personnel utilizing the equipment. This is a high-pressure system. While a substantial effort has been expended to make this equipment safe, simple and fool-proof to operate, it is strongly recommended that only personnel formally trained in the use of pneumatic pressure equipment be permitted to operate it. Potentially dangerous conditions could be produced through negligent handling or operation of the console due to the high pressure contained within the unit.
UPS3110 units are strictly for use with pneumatic pressures. Erroneous readings and potential damage could result from the introduction of hydraulic fluids into the internal tubing lines.

1.0 Introduction

Utilizing microprocessor technology, the UPS3000, rack-mountable UPS3110 and UPS3210 instruments offer a combination of features, performance, versatility and reliability not previously available in a single, self-contained pressure calibration instrument. The following list notes the features and benefits of each unit:
Three independent switch-selectable pressure ranges per instrument.
Nine button-selectable units (PSI, kPa, Bar, mBar, kg/cm2, mmHg, inHg, cmH2O, inH2O) plus percent of full scale may be displayed on instrument.
Accuracy of each range equal to or better than ±0.05% Full Scale.
Both “Gage” and “Absolute” pressure calibrations available via front panel switch selection.
Automatic self-check: Computer-controlled internal circuitry provides automatic maintenance of both zero and span calibration data to insure long-term stability and accuracy.
Digital Display: Eliminates parallax, interpolation and operator judgement errors. Large, bright, red LED digits provide excellent readability under all lighting conditions.
UPS3110 only - Using a manually adjustable regulator, the maximum system input pressure is adjusted to any desired value higher (typically 20 to 50%) than the full scale range of the device being tested. By virtue of this technique, the unit under test is fully protected from being inadvertently over-pressurized.
Fast Response: Pressure data refreshed and updated at the rate of 12 time s per second.
Data Output: Serial Data, 20 mA loop, ASCII code format with start, stop and parity bits supplied as standard practice. RS232 Simplex output available as an option.
Calibration Integrity: Tamper-proof design. Once calibrated, numerous safeguards guarantee the integrity of pressure readings obtained. Display prompting provides the operator with functional status information during both operation and calibration.
P ressure Media: UPS3000 and UPS3210, any gas or fluid compatible with 17-4 PH stainles s steel alloy. UPS3110, only gas compatible with 17-4 PH stainless steel alloy.
Simple Operation: All controls and indicators are accessible from the front panel. Accompanying operator's manual provides clear, concise instructions for system operation
S afe, Clean Operation: All pressure components are made of brass, copper, aluminum or stainless steel and proof-tested to at least 150% of maximum operating pressure. In addition, the UPS3110 system contains a high-pressure relief valve to protect both the operator and system components from harm in the event of inadvertent over-pressurization.
The heart of this indicator/calibration system is a highly stable and repeatable pressure transducer. These sensors produce an electrical output signal which is linearly proportional to the applied pressure. This transduction technique has been employed by CONDEC for many years and has realized hundreds of thousands of hours of reliable operation.
By combining these sensors with sophisticated microprocessor-based circuitry, an even higher degree of operational accuracy and precision has been accomplished. For example, computer-generated correction curves for both the non-linearity and the hysteresis of the sensors improve these characteristics by an order of magnitude or more. In addition, a “self-calibration” feature insures long-term accuracy by utilizing the computer to generate and control an internal “shunt calibration mode” of operation. The indicators full-scale reading is compared against, and if necessary, corrected to the digitally-stored value for full scale obtained at the time of initial pressure calibration.
The UPS3000 and UPS3210 indicators, as well as, the UPS3110 calibrator has capability for an internal, rechargeable 12 volt lead acid battery, which provides a minimum of 6 hours of complete usage, when battery is fully charged. An ON/OFF switch is provided to conserve energy when the instrument is not in use. It also has a
LO BATT indicator. After receiving and prior to operating new battery models, reinstall (+) cable, red wire, on
battery.
2 UPS3000/UPS3110/UPS3210 Operation & Maintenance Manual
With all its sophistication however, a great deal of effort has been expended to make the instruments simple to operate and easy to calibrate.
Two micro-metering valves and vernier are provided to control the UPS3110 pressure source while the digital display indicates precisely the magnitude of the applied test pressure. Also, a pair of simple push-button switches provide both “zeroing” of the pressure display and the selection of either the “Gage” or “Absolute” calibration mode. In like manner, the “Range” selection is accomplished via a clearly marked rotary switch. Over-pressure protection is provided on lower pressure UPS3110 models via a fully adjustable pressure regulator which is manually set for each new device being tested.
With respect to calibration, the instruments have been designed and programmed to be very user friendly in that they provide the operator with various prompting symbols and legends during each phase of the calibration sequence. Also, to prevent unauthorized tampering or calibrations, numerous features have been incorporated which greatly minimize this potential danger. Also, the electronic circuitry ha s been designed without any potentiometers or adjustments which eliminates the possibility of unwanted changes. Finally, the computer has been programmed with a series of internal self-diagnostic routines which continually monitor and check every bit of data stored and processed by this system, and immediately either notes or shuts down operation in the event of an out-of-tolerance reading or outright failures.
The following schematic provides an overview of the UPS3110’s function.

Digital Averaging is a technique whereby numerous update cycles are averaged together before the numerical display data is changed. In essence, this feature acts as a variable rate electronic filter to provide a more stable pressure indication reading.The “
AUTO” mode of this filter allows the display to update rapidly (12/sec.) when
the input pressure is being quickly changed and yet provides extremely stable display operation (3/sec.) when the desired pressure input value has been obtained.

Table 2-5. AZM Enable Switch Setting
The Automatic Zero Maintenance (AZM) feature is used to “hold” the indicator reading to a “zero” value as long as the actual pressure input is maintained at zero. If the input pressure changes by more than one half a least significant display digit between two consecutive display update cycles, the “hold” feature is automatically disabled and the exact magnitude of pressure being exerted will be displayed. In some applications, it may be better to operate the instrument without the AZM circuit enabled. If so, pressing the
ZERO push-button switch,
with zero pressure applied to the instrument, will guarantee that each new pressure cycle begins at zero.

3.0 Calibration and Adjustment Procedure

The simple step-by-step calibration sequence provided on the following pages will permit a qualified technician to calibrate an entire UPS3000, UPS3110 or UPS3210 instrument in a matter of 45 minutes.
However, it must be strongly emphasized that when performing these tests, the computer within the instrument is actually being re-programmed and as such, it is imperative that the pressure standard being used be in satisfactory operating condition and that the technician fully understands its operating characteristics and methods of usage. In addition, the (approximately 10 minutes) and electrically stabilized prior to performing a calibration cycle.
NOTE: The CONDEC Repair Lab is equipped to do calibrations on CONDEC calibrators and pressure standards.Calibrations include a certification and are traceable to N.I.S.T (see Material Authorization Form”).

3.1 Pneumatic Calibration Set-Up

Figure 3-1 defines a typical gage or absolute/gage calibration set-up using a floating piston type dead weight tester. While doing an ABSOLUTE Only Unit calibration, a vacuum pump with an indicator capable of reading PSIA will be required where the dead weight tester/pressure source is shown in below local barometric pressure.
NOTE: Any type of precision pressure or vacuum standard is acceptable as long as its basic accuracy is ±0.025% of point or better.
To permit proper calibration at least an “ON/OFF” and a “VENT” valve, connected as shown in Figure 3-1 must be provided.
UPS3000/UPS3110/UPS3210 itself must be properly warmed up
