Page 3 of 60 2.0 INTRODUCTION This Instruction Manual will familiarize you with the installation, accessories, trouble-shooting, after sales service information, general maintenance of the analyzer, etc. and will guide you through the various applications. Please read this Manual thoroughly before starting the operation. If you need any clarifications, feel free to contact your supplier.
Page 7: Set Up
Page 4 of 60 3.0 SET UP UNPACKING AND SETTING UP YOUR ANALYZER Remove the balance from the packing by carefully lifting it out of the box. Inside the box you will find everything needed to start using the analyzer- AC power cable Pan Support Stainless Steel Lower Chamber Insert...
Page 8: Assembling The Analyzer
Page 5 of 60 ASSEMBLING THE ANALYZER For best performance, let the analyzer warm up for 30 minutes before using. Locate the balance on a solid surface, free from vibration with good ventilation around it. Place the lower reflector (1) into the base of the weighing chamber Gently place the pan support (2) into the access hole.
Page 9: Leveling The Analyzer
Page 6 of 60 LEVELING THE ANALYZER After placing the balance in a suitable location, level it by using the spirit level on the rear of the analyzer. To level the balance turn the two adjustable feet at the rear of the analyzer until the bubble in the spirit level is centered.
Page 10: Locating And Protecting Your Analyzer
Page 7 of 60 LOCATING AND PROTECTING YOUR ANALYZER In order to keep your analyzer functioning at its best we suggest that you do the following: Avoid extremes of temperature. Do not place in direct sunlight or near air conditioning vents. Make sure there are no heat sensitive or flammable materials above the analyzer.
Page 11: Safety
Page 8 of 60 SAFETY This Moisture Analyzer complies with the European Council Directives and international standards for electromagnetic compatibility, and safety requirements. Improper use or handling can result in damage or injury. To prevent damage to the equipment, read these operating instructions thoroughly.
Page 12 Page 9 of 60 • Protect the Moisture Analyzer from external liquids. Clean any spills immediately. • If there is any visible damage to the Moisture Analyzer or the power cable, stop using the instrument immediately. Unplug the power and isolate the analyzer.
Page 13 Page 10 of 60 • Materials that emit toxic, caustic or noxious fumes should only be tested in suitable fume hoods or with other ventilation. • Materials that will have a film on the surface during drying may cause high internal pressures to be present.

Page 46: Analyzer Configuration Through The Serial Interface
Page 43 of 60 11.5 ANALYZER CONFIGURATION THROUGH THE SERIAL INTERFACE The analyzer can use the serial interface to set parameters for weighing test and for analyzer configuration. The parameters are set by sending a line of data that has the description and the setting desired. It is possible to create a text file that contains all the data necessary to set he test conditions for a particular test (or analyzer configuration) and send this to the analyzer.
Page 47: Balance Setup Parameters
Page 44 of 60 The current settings can be printed or observed as described in sections 6.1.2 and 6.3. 11.5.2 BALANCE SETUP PARAMETERS The parameters related to analyzer configuration are listed below. To change a test parameter it is necessary to send a command for the parameter to modify along with the value to change.
Page 48: Analyzer Recall Parameters
Page 45 of 60 When the analyzer receives a valid command, it will return the message E0. If an invalid input command is received, the command is returned as follows: Message returned Remarks The analyzer can not recognise this command. String length is not right.
Page 49: Continuous Output
Page 46 of 60 11.6 CONTINUOUS OUTPUT The balance can use the interface to send the weight only to the output. This setting is configured in the Serial Communications parameters, see section 10.1.1. When the output is set for Continuous the test reports are not printed during a drying test and test results are not stored.

Page 56: Sample Preparation
Page 53 of 60 14.0 SAMPLE PREPARATION Sample preparation is the single most important item for accurate results. The sample must be prepared so the whole of the sample is heated uniformly and the moisture is near the surface of the material. For powders no further preparation is necessary.
Page 57 Page 54 of 60 Some plastics also are not suitable for this type of method due to the very low percent moisture and the heat required to extract this moisture. KNOW THE MATERIAL In addition it is important to know enough about the materials so that you do not endanger or inconvenience others.
Page 58: Guidance Notes
Page 55 of 60 15.0 GUIDANCE NOTES The following guide notes are offered as examples of temperature, display update time and expected results when drying various substances. The preparation, distribution and amount of product can all significantly affect the results. It is important to find suitable procedures to process the material, usually by trial and error.
