Page 5: Introduction
How to Use This Manual This manual provides installation, operation, and maintenance information for all configurations of the Model 500. The identification tag on the rear panel of every Dynacalibrator is stamped with the unit’s complete model number, which reflects the exact unit configuration. A chart on the last page of the manual explains the model numbers.
Page 6 �� Figure 1: Model 500 plumbing schematic The output of the permeation chambers is fed forward to SV1 and SV2, respec- tively. When the front panel switches are ON for SPAN 1 and/or SPAN 2, then the respective carrier flows are routed through the valves’ C and NC ports and to the mixing tee, where the calibrated dilution stream is added and mixed into it to set the final concentration.
Page 7 Introduction Referring again to Figure 1, note that the dilution stream passes through scrubber #3 and feeds into differential pressure regulator DPR3. The Model 500 contains a dilution flow control valve and rotometer, plus a rotometer for SPAN 1 and SPAN 2 carrier flows. When energized, solenoid control valve SV1 opens to route carrier 1 flow to the mixing tee.
Page 8: Options
Introduction The Model 500 has four modes of operation – ZERO, SPAN 1, SPAN 2, and Both SPAN 1 and SPAN 2. When the calibrator mode is changed to ZERO, SPAN 1, or SPAN 2, a two position valve in the calibrator interrupts the sample input and substitutes the calibrator output to the analyzer.

Page 10: Getting Started
Getting Started Every Dynacalibrator is completely calibrated, thoroughly tested and inspected, and carefully packed prior to shipment. The carrier has assumed responsibility for its safe delivery upon acceptance of the shipment. Initial Receiving Inspection/Check On receipt of your unit, before signing the waybill and releasing the carrier’s agent, inspect the shipment for the following: 1.
Page 11: Concealed Damage
�� Figure 3: Dynacalibrator packaging Concealed Damage Concealed damage is damage which is not apparent until after the equipment has been unpacked and examined or tested. In the event that concealed damage is discovered, a written request for inspection must be forwarded to the carrier’s agent within 15 days of the delivery date.
Page 12: Unit Location
Getting Started Unit Location In general, the Dynacalibrator should be as close as possible to the analyzer to be calibrated, as long as: • the ambient temperature is at least 2°C below the selected operating temperature of the permeation chamber. •...

Dilution Overflow Chamber 500-0 500-1 Table 1: Dynacalibrator Model 500 rear panel connections X = Required connection blank = No connection Supply Inlet All Dynacalibrators except those with -1X input configurations (separate carrier and dilution inlet ports) are equipped with a supply inlet fitting. The supply inlet must be connected to an external pressurized source of carrier and dilution gas such as an external pump, a cylinder of compressed gas, etc.
Page 14: Overflow Vent
Span and Zero Outlets The primary outlet on the Model 500 is labeled SPAN OUTLET. The span outlet may be either permanently plumbed to the calibrate input port of an analyzer or temporarily connected to its sample input for calibration, depending on the capabilities of the analyzer.
Page 15: Front Panel Controls And Indicators
�� Figure 4: Model 500 front panel controls and indicators Front Panel Controls and Indicators The section entitled “Advanced Theory of Operation” beginning on page 24 includes more detailed information on the interrelation of the front-panel controls and indicators with the internal pneumatic and electrical flow of the units.
Page 16 CHAMBER switches and indicators Series 500 Dynacalibrators have two permeation chambers. Each chamber has a switch which places the chamber in line with the diluent stream, and two indica- tors to provide visual confirmation of the switch setting. Each chamber is func- tionally independent, so that the user can select either, both, or neither chamber to be in line with the diluent stream.
Page 17: Calculations
Sample Calculation Given: Permeation rate: 21,000 ng/min Cl @ 30°C Carrier flow: 500 ml/min Then: K * P Concentration (ppm) = (0.346)(21,000) = 14.5 ppm For zero reference measurement, remove the permeation device from the...
Page 18: Initial Power Up
The carrier inlet source must be able to provide at least 500 SCCM, and the dilution inlet must be able to source the maximum dilution flow, which may be as high as 20 SLPM.
Page 19: Setting The Chamber Temperature Manually
Setting the Chamber Temperature Manually To read the current set point: press and hold the button. To read the chassis environment temperature: press and hold the button. 1. To set the desired temperature, simultaneously press the buttons, then release them. The PNL light will start flashing, indicating the controller is in the temperature set mode.
Page 20: Setting The Chamber Temperature Via Serial Port (Rs-232)

Page 26: Analyzer Calibration
Analyzer Calibration After the power-up procedure has been completed and the chamber temp- erature and permeation device have reached equilibrium, the Dynacalibrator is ready to be connected to the analyzer being calibrated. Use a minimum length of tubing for the connection, and make sure none of the calibrator’s vents are blocked.
Page 27: Shutdown Procedure
Shutdown Procedure Dynacalibrators are designed to operate continuously; however, if it is necessary to turn the unit off, use the following procedures: 1. With the tool provided, rotate the panel lock screw 90° counterclockwise. 2. Gently pull the front panel assembly out. CAUTION: The permeation chamber cap may be hot.
Page 28: Advanced Theory Of Operation
Since the Model 500 can provide a wide dynamic range of span gas calibrations simply by changing the flow rate of the dilution gas, it is considered to be a multi-point calibrator of exceptional range, accuracy, and precision.
Page 29: Plumbing Configurations
There are two plumbing configurations available for Model 500 Dynacalibrators. The plumbing configuration is defined by the first digit of the 2-digit numerical suffix to the basic model number, e.g., Model 500-12 is equipped with plumbing configuration 1. The second digit of the 2-digit suffix defines the overall instru- ment gas flow capacity.
Page 30: Electrical Description
Electrical Description The basic wiring of the Model 500 is shown schematically in Figure 8. Dynacalibrators are powered from a benchtop style transformer on the rear panel. This is a switcher-style supply that allows a range of input voltage and frequency from 100 to 240 VAC at 50-60 Hz.
Page 31: Maintenance
Maintenance Since Dynacalibrators are designed for and generally used in applications that require continuous service, a planned routine maintenance program is highly recommended. Routine maintenance consists of inspection, cleaning, calibration, and leak checks. The table below lists the recommended checks and mainte- nance frequencies for continuous and non-continuous use.
Page 32: Carrier Flow Rate Verification
Maintenance 9. Inspect all assembly mountings for loose hardware, and tighten as necessary. 10. Rinse the fan screen and fan filter in clean water and blow dry with low- velocity air. 11. Reinstall the fan, fan filter, fan screen brackets, and fan screen using the four screws, lockwashers, and hex nuts.
Page 33: Chamber Temperature Calibration
Maintenance Chamber Temperature Calibration Prior to shipment, the permeation chamber digital temperature control is calibrated against the temperature of the gas in the permeation chamber using an NIST-traceable PRT, (platinum resistance thermometer). The results of this calibration have been supplied with your instrument. At this point, it is helpful to give an overview of the total calibration process.
Page 34: Troubleshooting
Troubleshooting If you intend to perform detailed troubleshooting on your Dynacalibrator, please first read the section entitled “Advanced Theory of Operation” which starts on page 24. The flow diagrams included there will provide significant help. Most gas flow problems can be isolated to a particular component using a low- pressure air source and a magnihelic pressure gauge.
Page 35: Component Isolation Method
5. Repeat steps 3 and 4 for each potential leak point in the suspect loop. 6. Tighten or remake any connection or joint that has been found to be leaking. Replace any component whose leak cannot be stopped by the tightening or remaking process.
