Maintenance AccuPyc II 1340 Maintenance Calibrating the Pycnometer You should check or calibrate the pycnometer every time you restart it. For a quick check, run an analysis with an empty cup to see how close the average volume is to 0. It should be ±0.05% of full-scale.
AccuPyc II 1340 Maintenance Replacing the Chamber Cap O-Ring Fine fibers and particles between the O-ring and its sealing surfaces can cause leaks, as can scratches or cuts in the O-ring or in the metal surfaces. When it is necessary to replace the O-ring, follow these steps.

If the pressure varies more than 0.005 psig/min, temperature instability or a leak may be indicated. Vent the system, then repeat steps 8 through 11 several times to verify that a leak is indicated. If a leak is indicated, call a Micromeritics Service Representative. Cleaning the Pycnometer The exterior casing of the pycnometer may be cleaned using a clean cloth, dampened with isopropyl alcohol (IPA), a mild detergent solution, or a 3% hydrogen peroxide solution.
AccuPyc II 1340 Maintenance Cleaning the Dust Filter (2000-cm units only) Dust from the sample may be carried into the instrument plumbing. A dust filter protects the valves to minimize valve leaks. When it is necessary to clean the filter, follow these steps: Close the gas line (Fill) valve.
Recovering from a Power Failure AccuPyc II 1340 Recovering from a Power Failure The pycnometer saves entered settings and collected data in case of a power failure. Set up parameters and data will still be present when power is restored. If an automatic operation was in progress when the power failure occurred, it will be canceled when the pycnometer restarts.

AccuPyc II 1340 Appendix E E. MULTIPLE ANALYSIS MODULES This Appendix provides information on attaching multiple analysis modules to a control mod- ule. You can have up to six analysis modules for one control module. In most cases, a control module also contains an analysis module in a single unit.
Page 130
Appendix E AccuPyc II 1340 2. Connect one external power supply cable to the back of the single unit system and another external power supply cable to each power adapter to be used to connect the analysis modules. 3. Connect a power cable to each external power supply.
AccuPyc II 1340 Appendix E Connecting One or More Analysis Modules to a Controller Some models of the AccuPyc require a Control module and an Analysis module as separate units. For example, the Glove box system and the 350-cm system. A Control module contains a keypad and a display, but does not contain a sample compartment.
Page 132
Appendix E AccuPyc II 1340 6. Attach the hardwired power adapter cable to the lower connector labeled Module Connection on the rear panel of the analysis module. Be sure to use the lower connector on the analysis module; the upper connector is for attaching another analysis module.
If you have a temperature-controlled AccuPyc, you must attach a circulating bath (not pro- vided by Micromeritics). This appendix provides information on attaching the bath, but it does not provide operating instructions for the bath (refer to the manufacturer’s operator’s manual for operating instructions).
Appendix F AccuPyc II 1340 Adding an Analysis Module Use these instructions when adding an Analysis module to an existing Temperature-controlled unit. 1. Be sure the controlling unit is turned off. If you have the Windows version of the AccuPyc, exit the application before turning off the analyzer.
AccuPyc II 1340 Appendix G G. SUPPORTED PRINTERS The AccuPyc provides support for a USB printer and includes the following printer drivers: • Canon Bubble Jet • Epson ESCP • Epson ESCP Raster • Epson ESCP2 • HP PCL 3 •...
AccuPyc II 1340 Appendix H H. RS-232 PIN ASSIGNMENT The AccuPyc is a standard DTE device. The RS-232 port on the rear panel of the AccuPyc can be used to attach an analytical balance for transfer of sample weight, or for transmitting data through a serial line to a computer.
AccuPyc II 1340 Appendix I I. KEYBOARD INTERFACE A computer keyboard attached to the USB port enables you to enter alphanumeric characters at certain prompts; for example, the Sample ID and Description prompts. So that you do not have to switch back and forth between the computer keyboard and the analyzer keypad, all system commands are available through the keyboard.

AccuPyc II 1340 Appendix J J. MULTIVOLUME INSERTS The MultiVolume Insert option enables you to analyze samples using smaller-sized sample chambers with your AccuPyc. MultiVolume Inserts are available as follows: • AccuPyc 2000-cm capacity; includes 650- and 1300 cm cups, supporting inserts and calibration standards.
Appendix J AccuPyc II 1340 Installing and Removing Inserts and Sample Cups Wear latex gloves when handling inserts and sample cups. Oils from your skin may contaminate the surface and affect analysis results. Refer to Handling System Components in Chapter 2 for recommendations on handling system components.
AccuPyc II 1340 Appendix J 10-, 3.5-, and 35-cm Inserts Simply remove the chamber cap and place the insert into the sample chamber. The insert should fit snugly in the chamber. Place the appropriate sample cup into the well of the insert.
Appendix J AccuPyc II 1340 1- and 0.1-cm Inserts Special tools are required for installing the 1- and 0.1-cm inserts; these tools are included in the appropriate MultiVolume kits. 1-cm Insert and Sample Cup Perform the following steps to install the 1-cm insert and sample cup: 1.
Page 145
AccuPyc II 1340 Appendix J 4. Place the cup into the insert, then tilt the tool to one side to remove it from the sample cup. 5. If using a fritted filter cap, place it onto the top of the insert.
Page 146
Appendix J AccuPyc II 1340 0.1-cm Insert The 0.1-cm insert does not have a separate sample cup. Because of its size, the sample cup is built into the insert. Perform the following steps to install and remove the 0.1-cm insert/sample cup: 1.
AccuPyc II 1340 Appendix J Calibrating Inserts An insert must be calibrated and its operation verified since it essentially becomes a different size sample chamber. Appropriate calibration standards are included in the MultiVolume kits. For example, if you have a 100-cm...

AccuPyc II 1340 Appendix K K. MULTIGAS OPTION The Multigas option enables you to use multiple gases with the AccuPyc without having to disconnect and reconnect each time you wish to use a different gas. The Multigas option con- nects to the gas inlet on the rear panel of the AccuPyc, providing connections for up to four gases.

Appendix K AccuPyc II 1340 5. Remove the protective caps from the ends of the gas entrance tubing, then remove the ferrules from the upper end of the tubing. 6. Remove the nut from the center port and slide it onto the end of the gas entrance tubing, then replace the front and rear ferrules.
AccuPyc II 1340 Appendix K Connecting the Gas Supply Four pieces of gas supply tubing are supplied, allowing you to connect up to four gases to the assembly. 1. Connect one end of the gas supply tubing to the gas supply (refer to Rear Panel Connections if you need assistance).
