The user can choose between milligrams and grams for the data output milligrams are recommended for the Cahn electrobalances. Be sure that you understand what each parameter should be before changing any of the fields!ДЇigure 11. This will invoke the configuration screen as shown in Figure 11, below. These values can also be accessed from the instrumentвЂ™s main panel by clicking on the Configuration button on the upper left corner of the panel. Communication settings for the Cahn electrobalance. The proper settings for the Cahn balances are shown in Table 1, below.

If this is the first time that the Java balance software is being used on this computer, the proper configuration values may need to be set for COM port, baud rate, etc. Instrument selection and configuration choice screens.

Select Cahn (only) and use the previous configuration file if one exists.ДЇigure 10. The software will then which balance is being used, and then query whether to use the existing configuration profile or not as shown in Figure 10, below. Once the user has logged in, the software will acknowledge login click вЂњOKвЂќ to proceed. Although the login page states that it is for the dual Mettler-Toledo balances, this software is intended for use only on the Cahn electrobalances.

The link to this manual functions, but the instructions to email the shore-based developer account is out of date (any help requests should be routed to instead). Use of the Java Balance software requires authentication to the LIMS, so once the software is started, a login screen will appear as shown in Figure 9.

The Cahn electrobalance in the Microbiology Radiation Van (Rad Van) is used to weigh small masses of isotopes and samples operation of that balance is not covered in this guide.

The Cahn uses the software to make the mass determination and record their values in the LIMS.

The Cahn electrobalances in the Chemistry lab are used to weigh samples for CHNS, Source Rock, coulometer analyses, and ICP hard rock/sediment preparation.

Press the power switch on the rear panel to turn the Cahn electrobalance off.

To power up the Cahn electrobalance, press the power switch on the rear panel.

Make sure both balance trays are clear and the doors are closed.

Make sure serial cables are connected to both balances and PC.

Balance Start-Up Turning the Balances On/Off A protocol of daily calibration verification, carried out by the responsible support staff, will provide the data necessary to make statements about the overall system performance. The user can verify calibration at any time by weighing a mass standard. The balances can only be calibrated in port when ship motion is minimal, or even on shore if possible.

#Cahn c 31 microbalance manually verification#

If calibration verification shows a problem in the system, any samples measured on that balance system since the last acceptable calibration verification must be reanalyzed. Calibration verification is run on a routine basis to ensure that the original instrument calibration is still valid. To attain accurate results for subsequent measurements, the balance systems must be calibrated and that calibration verified. The Cahn electrobalances are located in the Chemistry Laboratory and the Microbiology Radiation Van on the ship.ДЇigure 1. The in-house motion compensated software enables users to accurately measure a small mass on the moving ship. The Cahn 29 and C31 Automatic Electrobalances enable weighing of small masses (< 250mg) take care not to overload them (Figure ).

Cahn 29 and Cahn C31 Automatic Electrobalances This user guide is designed to help onboard laboratory technicians and visiting scientists use the balance program for weighing samples on the shipвЂ™s Cahn microbalances.
