The “Differential Weighing” Application 149 12.5 Using the “Differential Weighing” Application This section describes how to work with the “Differential Weighing” application and print the results. 12.5.1 The Different Methods of Differential Weighing The “Differential Weighing” application supports three possible methods for performing differential weighing. These three methods are described in the following.
The “Differential Weighing” Application 150 Method 3 (user-defined) While methods 1 and 2 automatically follow on from one sample to the next, method 3 permits the user to define the operating sequence, i.e. the taring, weighing in, and residual weighing can be performed as individual steps for each sample. It is therefore not obligatory to carry out all 3 steps for a particular sample before moving on to the next.
The “Differential Weighing” Application 151 For specific cases, you can also activate these three function keys. These enable you to transfer the first tare value to all further samples, and allow differential weighing for a series without taring (section 12.5.6). 12.5.3 Differential Weighing: Automatic Procedure This description only applies if you have selected the automatic procedure for the series. Note: The automatic procedure guides you through method 1 or 2.
The “Differential Weighing” Application 152 When the balance has determined the tare weight, you are prompted to begin weighing. To perform weighing in, add the weighing sample to the container and then press “OK”. While the balance is determining the weight, a corresponding message is displayed. Once weighing in is complete, you are prompted to remove the sample. Remove the sample vessel containing the sample and confirm with “OK”. Taring and weighing in of the first sample in the series is now complete.
The “Differential Weighing” Application 153 The balance displays the first sample in the series for which nocorresponding residual weight values are available. If you want to perform residual weighing for a different sample, press the arrow key at the bottom of the window. In this example, however, we presume that you want to start with the first sample. Confirm this by pressing “OK”. Wait until the balance prompts you to load the selected sample for residual weighing.
The “Differential Weighing” Application 154 If the results for one sample take up several windows, you can use the scroll buttons at the bottom left of the screen to switch between the individual results windows. “Diff.% 1”: Difference between initial weigh-in and 1st residual weight of the sample as a percentage of the initial weight (weigh-in value) “Abs.
The “Differential Weighing” Application 155 12.5.6 Additional Options This section describes some further functions of the “Differential Weighing” application. Deleting a single value If you realize immediately after entering a value (tare, weigh in, residual weighing) that you have made a error, you can delete the last entered value using the “CL value” function key. However, this is only possible if no menu has been called, and if you do not exit the application in the meantime.
The “Differential Weighing” Application 156 When the function key is pressed, the prompt opposite appears. When you respond with yes, the tare weight of the first sample is copied for all further samples in the current series (as long as no tare weight has already been defined for these samples). Differential weighing without tare For certain applications in which no tare vessels are used (e.g. filter weighing), you can suppress tare determination for the whole series. This saves an operating step.
The “LabX Client” application 157 13 The “LabX Client” application This section provides an introduction to the “LabX Client” application. It provides information on starting the application and the setting options. Please note that all settings for the “LabX Client” application are saved under the active user profile, so each user can make their own settings for this application. Because of this, first make sure that you have selected the desired user profile. 13.
Firmware (software) updates 158 14 Firmware (software) updates METTLER TOLEDO is continuously improving its balance firmware (software) for the benefit of customers. So that the customer can benefit quickly and easily from further developments, METTLER TOLEDO makes the latest firmware versions available on the Internet.The firmware made available on the Internet has been developed and tested by Mettler-Toledo AG using processes that meet the guidelines of ISO 9001.
Error and status messages 159 15 Error and status messages 15.1 Error messages occurring during normal operation Most error messages appear in plain text directly in the respective application, and usually accompanied by a text describing how to correct the error. Error messages of this type are self-explanatory and therefore not mentioned below. The following error messages can appear instead of the weighing result: Overload The weight on the pan exceeds the weighing capacity of the balance.
Error and status messages 160 15.3 Status messages Status messages are displayed by means of small icons (symbols) in the top right of the display (under the date and time) (section 2.2). The status icons indicate the following: The balance would like to carry out a fully automatic ProFACT adjustment (see Operating instructions – Part 3) but is unable because another operating sequence is running.

Appendix 162 16.2 SOPs - Standard Operating Procedures In the documentation of a GLP test, the SOPs are a small, but very important part. Practical experience confirms that SOPs written in-house are followed much better than SOPs written by an an external, anonymous source. You will find below a brief overview of the responsibilities in relation to SOPs, as well as a checklist for creating an SOP.
