About This Manual

This manual is intended for use by service technicians responsible for installing and servicing the DLR3110 Digital Pressure Calibrator.
The DLR3110 series rack-mount combines the DLR Digital Pressure Calibrator with the Orion vernier for calibration of a wide variety of pressure sensing and measuring devices.
The DLR3110 utilizes a repeatable sensor coupled to microprocessor-based electronic circuitry and a selectable units conversion display system to provide digital representation of measured pressure. The unit has one test port. Dependent on model, a front panel mounted gauge tells the operator system pressure and includes a pressure regulator so the operator can not over-pressure a unit under test. Test hose is supplied standard for the customer. Front panel buttons provide

equipment. This is a high-pressure system. Only personnel formally trained in the use of pneumatic pressure equipment should be permitted to operate it. Potentially dangerous conditions can be produced through negligent handling or operation of the console due to the high pressure used within the unit.
These 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.
Before attempting to use either style pressure calibrator, the following instructions must be read and understood by personnel using the

selection of the desired functions, including zeroing (GAGE models only).

1.0 Introduction

Using microprocessor technology, the rack-mountable DLR3110 instrument offers a combination of features, performance, versatility and reliability not previously available in a single, rack-mount pressure calibration instrument. Some of the features of the DLR3110 are listed below:
• Streamlined, multi-function keyboard.
• Selectable configurations, automatic set-up mode and multiple conversion units.
•Based on model, accuracy equal to or better than ±0.05%, ±0.1% or ±0.25% of indicated value from 20% of full scale.
•Alpha-numeric display prompting provides the operator with functional status information during both operation and calibration.
•A manually adjustable regulator (when applicable) allows the maximum system input pressure to be adjusted to any desired value higher (typically 20 – 50%) than the full scale range of the device being tested. This regulator helps protect the unit under test from being inadvertently over-pressurized.
•No manual alignment or potentiometer adjustments are required for system calibration. (50,000 displayed graduations; ten-point linearity compensation; automatic gain adjustment).
•Calibration integrity: Tamper-proof design. Once calibrated, numerous safeguards guarantee the integrity of pressure readings obtained.
•Operation: All controls, indicators and test port are accessible from the front panel. A version with test port on rear of unit is available by special order. See Section 3.0 on page 8 for instructions on system operation.
•For safe, 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 system contains a high-pressure burst disk and relief valves to protect both the operator and system components from harm in the event of inadvertent over-pressurization.
The heart of this calibration system is a stable and repeatable pressure transducer. These sensors produce an electrical output signal that is linearly proportional to the applied pressure.

By combining these sensors with 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.
Two micro-metering valves and vernier are provided to control the external nitrogen source while the digital display indicates the magnitude of the applied test pressure. Also, a push-button switch provides the “zeroing” of the pressure display (on GAGE models). Over-pressure protection, based on model, is provided via a fully adjustable pressure regulator which is manually set for each new device being tested.
Figure 1-1 provides an overview of the DLR3110’s function.

3.0 Operation

The following sections provide instructions on various operation procedures for the DLR3110.

3.1 Initial Setup Procedure

To prepare for actual calibration usage, see Figure 3-1 on page 9 and proceed as follows:
1. Check that the INPUT valve (1) is closed (rotate clockwise until it stops) and that the VENT valve (2) is open (two turns counter-clockwise from its stop).
2. Plug in the power cord (see Section 2.3 on page 3) and power up the unit by pressing the power switch (3). Allow at least 10 minutes warm-up time.
3. If applicable, use the PRESSURE LIMIT CONTROL REGULATOR (4) to adjust the maximum system input pressure, as read by the PRESSURE LIMIT MONITOR (5), to any desired value higher (typically 20–50% higher) than the full-scale range of the Device-Under-Test (DUT). This procedure fully protects the DUT from being accidentally over-pressurized.
4. Connect the male end of the test hose to the TEST PORT (6) fitting.
NOTE: DLR3110 may be ordered with Test port on rear of unit. See Section 2.3 on page 3.
5. Connect the swivel fitting end (7/16-20) of the test (output) hose to the DUT using adapters if required. Tighten all connections properly.

3.2 Pressure Measurement Sequence (Gage)

Use the following steps to measure pressure with the GAGE model DLR3110:
1. With reference to Figure 3-1 on page 9, check that the indicator on the right end of the display indicates
Gage
(8). If not, see Section 5.11 on page 21.

2. Press and release the the display returns to a (2) is open, by momentarily depressing the
3. To apply pressure, close the VENT the INPUT valve (1) approximately 1/2 turn counter-clockwise until the numerical display begins to move. The pressure may change rapidly until reaching approximately 90% of the desired final value.
4. Use either the INPUT (1) or VENT valve (2) to obtain a specific pressure reading. Both provide precise control. As the pressure approaches the desired value, the valve being used for control should be rotated slowly clockwise to its closed position. With a little experience, pressure values very close to the desired final value can be quickly achieved.
5. To obtain exact pressure readings, slowly rotate the VERNIER control knob (10) in the direction required (clockwise to increase pressure) as indicated by the electronic numerical display.

3.3 Pressure Measurement Sequence (Absolute)

Use the following steps to measure pressure with the ABSOLUTE model DLR3110:
1. With reference to Figure 3-1 on page 9, check that the indicator on the right end of the display indicates
Abs
(9). If not, see Section 5.11 on page 21.
2. If only pressure measurements greater than barometric are required, continue to step 2.1. If pressure measurements above and below atmospheric pressure are required go to step 3.
a) To apply pressure, close the VENT valve (2) by turning clockwise approximately two times until it
stops and open the INPUT valve (1) by turning counter-clockwise approximately 1/2 turn until the numerical display begins to move. In general, the pressure may be changed rapidly until reaching approximately 90% of the desired final value.
b) Use either the INPUT (1) or VENT valve (2) to obtain a specific pressure reading. Both provide
precise control. As the pressure approaches the desired value, the valve being used for control should be rotated slowly clockwise to its closed position. With a little experience, pressure values very close to the desired final value may be quickly achieved.
c) To obtain exact pressure readings, slowly rotate the VERNIER control knob (10) in the direction
required (clockwise to increase pressure) as indicated by the electronic numerical display.
and then

3. If pressure measurements above and below atmospheric pressure are required, connect a VACUUM PUMP to the VACUUM/VENT port (2) as shown in Figure 2-1 on page 3.
4. Open the VENT valve (2), close the INPUT valve (1) and apply power to the vacuum pump and allow it to evacuate the system for several minutes or until the digital display reading reaches equilibrium near 0 PSIA.
5. With the vacuum pump still running, close the VENT valve (2) and check for system leaks. If there are none, continue to step 5.1.
a) To apply pressure, close the VENT valve (2) by turning clockwise approximately two turns to its
stop and open the INPUT valve (1) by turning counter-clockwise approximately 1/2 turn until the numerical display begins to move. In general, the pressure may be changed rapidly until reaching approximately 90% of it desired final value.
b) Use either the INPUT (1) or VENT valve (2) to obtain a specific pressure reading. Both provide
precise control. As the pressure approaches the desired value, the valve being used for control should be rotated slowly clockwise to its closed position. With a little experience, pressure values very close to the desired final value may be quickly achieved.
c) To obtain exact pressure readings, slowly rotate the VERNIER control (10) knob in the direction
required (clockwise to increase pressure) as indicated by the electronic numerical display.

4.0 Re-Calibration Only

NOTE: This section is for the technician that is familiar with the front keyboard menus and is doing nothing more than a re-calibration. The re-calibration must be done in the same base units as originally calibrated. For a more in-depth configuration and calibration explanation, see Section 5.0 on page 12.
The step-by-step calibration sequence provided on the following pages permits a qualified technician to calibrate an entire DLR3110 instrument in approximately 45 minutes.
The instrument has been designed and programmed to 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 to minimize this potential danger.
However, it must be emphasized that when performing these tests, the computer within the DLR3110 is actually being re-programmed and as such, it is imperative that the pressure standard being used is in satisfactory operating condition and that the technician fully understands its operating characteristics and methods of usage. In addition, the DLR3110 itself must be warmed up for approximately 30 minutes and electrically stabilized prior to performing a calibration cycle.

4.1 Pneumatic Calibration Set-Up

Figure 4-1 on page 11 defines a typical calibration set-up using a floating piston type dead weight tester. However, any type of precision standard is acceptable as long as its basic accuracy is twice that of the DLR3110’s or better.
To permit proper calibration at least an on/off and a vent valve must be provided (connected as shown in Figure 4-1 on page 11).

5.0 Configuration and Calibration
The following sections cover configuration and calibration of the DLR3110. For information on calibrating the unit without configuration changes, see Section 4.0 on page 10.
During the following procedures, the computer within the DLR3110 is actually being re-programmed. The pressure standard being used during calibration should be in satisfactory condition and fully understood by the service technician. In addition, the DLR3110 must be warmed up for approximately 30 minutes and electrically stabilized prior to performing a calibration cycle.

5.7 Modifying Data

Data values previously set are easily altered by pressing either of the horizontal arrow keys to enter the modification mode. Upon entering the mode, the least significant digit indicates the current position in the data that can be changed. Press the desired position indicated by the flashing digit, then use the
UP or DOWN arrow key to increment or decrement
the value of the selected digit. Once the new data value has been set, press the abort. If an abort is issued, the data reverts back to its former value. The display prompts with

accordingly.

5.8 Span Calibration Points

There are a total of 10 calibration points (SPAN 1 - 10 CAL TARGET) which are sequentially entered. It is not required that all calibration points be entered. If calibration is performed with less than 10 points, the curve is extrapolated to full capacity based upon the slope correction between the last two entered SPAN CAL points. In the example below, if only four span calibration points were entered (SPAN 1 to SPAN 4), the slope correction from SPAN 4 to full capacity would be defined by the computed slope between SPAN 3 and SPAN 4.
NOTE: If fewer than 10 SPAN CAL points are desired during calibration, simply step past the remaining calibration points using the DOWN arrow key, until the HYSTERESIS calibration point is reached.

5.9 Resetting Span Calibration Points

To reset the span calibration points, use the DOWN arrow key to step to the desired SPAN CAL point and then press the
CE key. The correction factor of the selected SPAN CAL point and all others beyond will be reset to
unity (see Section 5.6 on page 16).
NOTE: X’s shown on LED display and alpha-numeric display columns represent existing data.
After a reset has been performed, entry of new SPAN CAL points proceeds as described in Section 5.6.1 on page 17, starting with step 3.
NOTE: If all 10 SPAN CAL points are not used in the calibration, the last span calibration point to appear (SPAN x CAL TARGET=xx.xx) is not an entered correction point. It only indicates the next span calibration that can be entered.

5.10 Overwriting Span Calibration Points and Hysteresis

Any SPAN CAL point can be overwritten with a new value provided that it remains within the range bounded by the span calibration points above and below the span point to be overwritten. Figure 5-6 on page 20 shows SPAN 2 CAL point being redefined within the boundaries set by SPAN 1 and SPAN 3. HYSTERESIS can also be overwritten as long as the new entry is below 80% of the full capacity value. For information on how to reach SPAN CAL point and HYSTERESIS, see Section 5.6 on page 16.

6.0 Serial Input/Output

The DLR3110 offers easy access and configuration of two serial communication ports. Both communication ports are ASCII-compatible and thus the serial data output formats are compatible with most printers, scoreboards, or other remote serial devices. Port One may be configured for bi-directional full duplex or half duplex (duplex = two way communication) mode of operation while Port Two is restricted to a simplex output mode only (simplex = one way communication). The two communication ports support both RS232 and 20 mA current loop (passive or active). In addition, Port One also supports RS485, or RS422 communication.
The transmission of serial output data strings can be initiated in one of three ways: on demand output, continuous output, or by serially soliciting the indicator in a duplex (bi-directional) mode of communication. Section 5.13 on page 23 for configuring.

Port 1 (set up selections)

• OFF - Turns Port One off
•
PRINTER - On demand printout of the data when the PRINT key is pressed or the remote print input is
issued. The printer mode is a simplex output mode.
•
DUPLEX - Bi-directional communication in which serial data can be both received and transmitted
between the indicator and a remote device such as a computer.
•
SIMPLEX - Continuous serial transmission

Port 2 (set up selections) - No DUPLEX communication

• OFF - Turns Port Two of f
•
PRINTER - On demand printout of the data when the PRINT key is pressed or the remote print input is
issued. The printer mode is a simplex output mode.
•
SIMPLEX - Continuous serial transmission
See

6.1 ASCII - Data Formats

Each serial character sent out in the serial data string is in ASCII - compatible format. The data format selection is based on parity selection in the I/O set-up mode (Refer to Section 5.13 on page 23 for configuration of Serial Ports). The data format for each ASCII character is of the general form
One ASCII character consists of:
(1) Start Bit, (7) or (8) Data Bits (data bits are the bits that actually encode for the ASCII character) (1) or No Parity Bit (1) Stop Bit
Bit Parity Selection Odd Even Mark None

applicable. Leading zeroes are suppressed and an ASCII space character (20H) is
transmitted to hold the position of each leading zero. space = Space character (20H) Units = A character field that defines the current units of the display data (examples: PSI, cmH2O,
Kpa, mBAR, BAR, PASCAL). Mode = An alpha character field that describes the current mode the indicator is in. GAGE/

6.3 Duplex (Port One Only)

The selection of the DUPLEX format is only available on Port One. This selection sets up port 1 for bidirectional communication in RS485, RS232, or 20mA. Because of the extensive list of command instructions that can be issued to the indicator from a host computer, the scope of this section is limited to defining those commands that are most often utilized. A more extensive document detailing the full operational parameters for serial duplex protocol is available upon request from CONDEC. Ask for Duplex Serial Protocol Manual, PN 74845.
• The duplex protocol includes the following basic functions: d) Setup entry and recall e) Current weight/pressure data recall f) Calibration and correction recall and entry g) All front panel key functions h) Temperature calibration and correction recall and entry
Serial Input/Output 33
Page 38
• The protocol between the “standard” full duplex and the RS485 only differ by the addition of the origin and destination address characters.
•All functions performed via the front panel keys can also be performed via the serial full duplex communications.

6.3.1 Full Duplex Protocol

Communications from the host computer to the DLR:
<*><DD><OO><cmd><{><data entry><}><CHECK><CR>
NOTE: Destination and origin characters (<DD> and <OO>) are only sent in RS485 format
Response from the DLR:
<:><OO><DD><cmd r><{><data resp><}><CHECK><CR>
Where:
"<",">" = Brackets are not sent * = Message from master (host computer [2AH]) : = Response from DLR3110 (3AH) DD = DLR unit address (two digit) if in RS485 OO = Master address (fixed at 00) if in RS485
If RS485 mode is not selected the "DD" and "OO" are not transmitted.
cmd = Three character command to DLR3110 cmd r = Three character command echoed from DLR3110 { = Start of data character (7BH) } = End of data character (7DH)
'{' and '}' only sent if data entry or recall.
data entry = Data entered into DLR if entry command data resp = Data response from DLR if in response CHECK = Optional two character check if selected CR = Message terminator (0DH)
A "LF" character following the "CR" is ignored. All characters following the "CR" and preceding the "*" is ignored.

6.3.2 Command Code <cmd> Description

The <cmd> consists of three (3) characters “ppt” where:
pp = the command parameter (see chart I) t = the command type
The three (3) command types (t) are as follows:
Direct cmd code = < D > character (44H). “D” commands have no data associated with them
Examples:
•General commands (Zero, Tare, etc.)

6.4 Continuous Simplex Output (Compressed Format)

The pressure value that is compressed consists of the polarity and pressure value including the <dp>. The data in the compress mode is based on the six-digit display plus a <dp> when required. To enable see Section 5.13.1 on page 24.
The data output format of the serial transmission is of the general form shown below:
<-/D06><D05><D04><D03><D02><D01><lb1><lb2><lb3><lb4>
Where:
<-/D06> = The minus character if present and the most significant digit if positive. <D05>--<D01> = The pressure digits. <lb1>--<lb4> = Rest of data not effected (for example: units, mode). The floating <dp> is added to the string when required. Therefore, the string is one character longer
when a <dp> is added.
Examples:
100.0--<sp> <sp> <1> <0> <0> <dp> <0> --­123456-- <1> <2> <3> <4> <5> <6> ---
- 345.6 -- <-> <sp> <3> <4> <5> <dp> <6> ---
6.5 Serial Output Wiring and Hardware Configuration
